Quantum computing poses an existential threat to current encryption infrastructure while simultaneously offering unprecedented security through quantum cryptographic protocols. The cybersecurity community faces a dual imperative: migrating to post-quantum cryptographic standards resistant to quantum attacks while deploying quantum key distribution (QKD) for long-term information security.

Post-Quantum Cryptography (PQC) standards from NIST include CRYSTALS-Kyber (lattice-based key encapsulation), CRYSTALS-Dilithium (lattice-based digital signatures), SPHINCS+ (hash-based signatures), and FALCON. These algorithms rely on mathematically hard problems believed resistant to quantum attacks.

India's Quantum Cryptography and Cybersecurity Initiatives

India's National Quantum Mission includes quantum communication as one of four verticals with substantial allocation. The Thematic Hub on Quantum Communication at IIT Madras, established as the IITM C-DOT Samgnya Technologies Foundation, focuses on quantum cryptography, post-quantum security, quantum key distribution networks, quantum memory, quantum repeaters, and satellite-enabled quantum communication.

The Department of Telecommunications (DoT) and Ministry of Electronics and Information Technology (MeitY) coordinate quantum-safe migration for critical infrastructure. The Defence Research and Development Organisation (DRDO) leads quantum-safe security scheme design and testing according to NQM documentation.

Bengaluru-based QNu Labs, selected under NQM startup support in November 2024, develops quantum-safe cryptography and secure communication systems including QKD systems and quantum random number generators for defense, telecom, and data security applications.

The NQM targets developing quantum-resilient encryption and post-quantum cryptographic frameworks for India's critical infrastructure, with satellite-based secure quantum communications over 2000km and inter-city quantum key distribution as specific deliverables.

Lastwall expands with $16 million for quantum defensesquantum-computing

Lastwall expands with $16 million for quantum defenses

A $16 million investment will allow Lastwall, a New Brunswick-based cybersecurity firm, to expand its operations in Canada and proactively defend against future quantum cyberattacks. The funding supports Lastwall’s work to secure digital systems before the emergence of quantum computers capable of breaking current cryptography. The company’s headquarters in Fredericton positions the city as a developing hub for advanced cybersecurity focused on this emerging threat. Lastwall Secures $16 Million for Quantum Cybersecurity Expansion Lastwall is actively building defenses against a threat that does not yet exist; the company recently secured $16 million to expand its quantum cybersecurity operations within Canada. This investment allows Lastwall to proactively address vulnerabilities posed by future quantum computers, rather than reacting to breaches as they occur, a strategy Karl Holmqvist, founder and CEO, describes as essential for long-term security, the company says. The company’s platform employs identity-based credentials, including biometric data, to fortify systems against intrusion, a method Holmqvist asserts is more robust than conventional two-factor authentication. The urgency stems from the potential for “store now, decrypt later” attacks, where malicious actors capture encrypted data with the intention of deciphering it once quantum computing power matures; Holmqvist explained that this is a problem when secrets need to remain confidential. Communications Security Establishment Canada acknowledges the emerging risk, noting that experts predict quantum computers capable of breaking current encryption could emerge by the 2030s. As a result, organizations must invest in quantum-resistant technologies to safeguard sensitive data and systems, said Janny Bender Asselin, a spokesperson for the agency. Lastwall’s approach mirrors a broader governmental shift toward bolstering national resilience through domestic technological capabilities; the government has set

This is a core operation for quantum repeaters, enabling such crucial tasks as long-distance quantum communication and distributed quantum computing. In this work, we introduce a method for searching for entanglement distillation protocols and, using this technique, distil qubit Werner states at a higher rate than could be achieved using previously discovered protocols. In particular, we demonstrate the advantage of our new distillation strategy by improving the best-known lower bound for the two-way-assisted quantum capacity of the qubit depolarising channel across a wide range of channel parameters, making progress in one of the long-standing problems of quantum information theory.

Lattice-Based Cryptography Explainedquantum-computing

Lattice-Based Cryptography Explained

Lattice-based cryptography is the branch of modern encryption that hides its secrets inside a grid of points in high-dimensional space. It is the mathematics underneath the two headline standards the United States published in 2024, and it is the reason most of the internet’s future key exchanges will look nothing like the ones running today. This page is about the machinery rather than the policy. If you want the wider picture of the migration, our guide to post-quantum cryptography covers it, and the vendor landscape is mapped separately. What follows is the geometry that lattice-based cryptography is built from, the hard problems, the protocols standing on them, and an honest account of why anyone believes a quantum computer cannot break them. Core assumption Finding short or close vectors in a high-dimensional lattice is hard, even with a quantum computer Workhorse problem Learning With Errors, introduced by Oded Regev in 2005 Standardised as ML-KEM in FIPS 203 and ML-DSA in FIPS 204, both published 13 August 2024 Descended from CRYSTALS-Kyber and CRYSTALS-Dilithium, submitted to the NIST process in November 2017 Status of the security claim No known efficient quantum attack, which is not the same thing as a proof Practical cost Keys and signatures measured in kilobytes rather than tens of bytes Key takeaways A lattice is a repeating grid of points, and the hard part is finding the nearest one. In two dimensions a child can do it by eye, and in the several hundred dimensions lattice-based cryptography uses, nobody knows how. The same lattice can be described by an easy basis or an impossible one. That asymmetry between a short near-orthogonal description and a long skewed one is the trapdoor the whole field is built on. Learning With Errors is linear algebra with the answers slightly wrong. Remove the errors and the system falls to schoolbook elimination, add them back and no efficient method is known. Quantum resistance here is an absence of attack, not a theor

Hirata & Tsukada Build Language for Quantum-Controlled Channelsquantum-computing

Hirata & Tsukada Build Language for Quantum-Controlled Channels

A new theoretical study proposes a quantum programming language capable of expressing one of quantum information science’s most powerful control mechanisms: the quantum SWITCH. Kengo Hirata of Kyoto University and Takeshi Tsukada of Chiba University have developed a programming framework that overcomes a fundamental obstacle in controlling quantum programs with qubits. By introducing a novel linear type system, the researchers show that quantum programs involving general quantum channels can be described in a mathematically consistent way while naturally supporting the quantum SWITCH. Quantum computers derive their power from the ability of quantum data to exist in superposition, allowing a qubit to represent multiple states simultaneously. This naturally raises a deeper question: if quantum data can exist in superposition, can entire quantum programs also be placed into superposition? The quantum SWITCH, which allows the order of two quantum operations to depend on a quantum control state, has emerged as one of the best-known examples of quantum-controlled computation and has attracted considerable attention in quantum information theory. A common method for controlling quantum programs is through controlled operations. In this approach, a control qubit determines whether an operation F is applied when the qubit is in the state |1⟩ or whether the identity operation is performed when the qubit is in the state |0⟩. While this construction works well for unitary operations, Hirata and Tsukada show that it is not well-defined for general quantum channels, which include measurements, noise, and other non-unitary processes that occur in realistic quantum systems. The researchers identify the source of this limitation as the way quantum conditional branching handles measurements. Specifically, the measurements performed in the then and else branches of a conditional statement may not correspond to one another, preventing the overall program from representing a valid quant

Topological State-Aware Simulation Framework for Inter-Satellite Twin-Field QKD Networksquantum-computing

Topological State-Aware Simulation Framework for Inter-Satellite Twin-Field QKD Networks

--> Quantum Physics arXiv:2608.12659 (quant-ph) [Submitted on 12 Aug 2026] Title:Topological State-Aware Simulation Framework for Inter-Satellite Twin-Field QKD Networks Authors:Sergio Vázquez-Pozo, Juan Manuel Murillo View a PDF of the paper titled Topological State-Aware Simulation Framework for Inter-Satellite Twin-Field QKD Networks, by Sergio V\'azquez-Pozo and 1 other authors View PDF HTML (experimental) Abstract:Inter-satellite links (ISLs) are the mandatory backbone for global quantum networks. While Twin-Field Quantum Key Distribution (TF-QKD) successfully surpasses linear rate-loss bounds, its extreme phase sensitivity makes it highly vulnerable to dynamic, non-IID (Independent and Identically Distributed) orbital environments. In composable finite-key analyses governed by the Generalized Entropy Accumulation Theorem (GEAT), traditional adaptive post-selection heuristics either violate strict independence conditions or incur massive second-order penalties that collapse the secret key rate. To overcome this, we introduce a reference-only topological post-selection oracle. By modeling the constellation as a Cellular Sheaf and applying Topological Data Analysis (TDA), our protocol derives a public acceptance event ($\Omega$) exclusively from classical beacon telemetry. To rigorously validate this mechanism, we develop a modular simulation framework equipped with stochastic noise injection and an explicit GEAT security ledger. Simulations across 2,000-5,000 km ISL separations compare the same Hodge-Koopman gate with TDA disabled and enabled. At 2,000 km, the median conditional candidate rates are $2.14 \times 10^{-6}$ and $5.87 \times 10^{-7}$ bit per emitted pulse, respectively; both configurations return zero at 3,000-5,000 km. TDA is active in all 4,788 evaluated windows, but does not extend the positive-candidate range in this scenario. These exported rates are conditional numerical candidates: the full protocol-level composable-security proof remains inco

A Finite-Window Recovery Hierarchy for Local Quantum Memoryquantum-computing

A Finite-Window Recovery Hierarchy for Local Quantum Memory

--> Quantum Physics arXiv:2608.12803 (quant-ph) [Submitted on 13 Aug 2026] Title:A Finite-Window Recovery Hierarchy for Local Quantum Memory Authors:Zheng An, Dongyang Cao, Jiangyu Cui View a PDF of the paper titled A Finite-Window Recovery Hierarchy for Local Quantum Memory, by Zheng An and 2 other authors View PDF HTML (experimental) Abstract:When quantum information initially stored in a local qubit disappears, it need not be lost: it may have moved into nearby degrees of freedom or become inaccessible to shallow local control. We introduce finite-window recoverability as an operational channel benchmark that separates these possibilities. It compares optimal recovery from the target site, recovery by a bounded-depth decoder on a finite window, and the unrestricted optimum for that window. Its operational component, local variational recovery, uses local state preparation, window-local control, and target-qubit Pauli readout to certify recoverable memory beyond the target and quantify how much of the same-window advantage is accessible to shallow control. In a disordered kicked-Ising Floquet chain, a depth-6 decoder on a five-site window realizes $Q^{\mathrm{opt}}_0<Q^{\mathrm{shallow}}_2<Q^{\mathrm{opt}}_2$ across the crossover regime, with positive certified gain for most disorder realizations and substantial shallow-accessibility fractions. The signal differs from target-site persistence and reconstructed coherent-information increments. Positive radius-2 gain also persists when the task is embedded in longer open chains using an independent tensor-network backend. Guided by this hierarchy, we test a carrier-deletion task in which the original target register is reset after the dynamics. A depth-8 decoder repairs the input from a radius-3 surrounding halo with held-out median $F_{\mathrm{avg}}=0.758$, above the single-qubit classical benchmark $2/3$, and outperforms optimal one-, two-, and three-site halo-subwindow counterfactuals. These results establis

Petz–Rényi Channel Information Is Superadditive for Every α Between 1/2 and 1quantum-computing

Petz–Rényi Channel Information Is Superadditive for Every α Between 1/2 and 1

A new theoretical study has revealed that using multiple copies of a quantum communication channel in a correlated way can improve transmission reliability without increasing the maximum communication rate. Hao-Chung Cheng of the National Taiwan University and Mario Berta of the RWTH Aachen University prove that the Petz–Rényi channel information is strictly superadditive for every Rényi parameter α between 1/2 and 1, demonstrating that entanglement-assisted quantum communication can become more reliable through joint channel use even though its capacity remains fundamentally additive. Entanglement-assisted communication allows a sender and receiver to share entanglement before transmitting information through a quantum channel. While previous results established that joint encodings across multiple channel uses cannot increase the ultimate communication rate, the new work shows that they can enhance the probability of successful communication by improving the random-coding error exponent, a measure of how rapidly transmission errors decrease as larger codes are used. The researchers establish this phenomenon analytically for measurement channels, a class of entanglement-breaking channels whose unassisted communication capacity is already known to be additive. Despite their inability to preserve quantum entanglement, these channels still exhibit a genuine multi-copy reliability enhancement under entanglement-assisted communication. Remarkably, the improvement does not require entanglement between the transmitted channel inputs. Instead, the superadditivity is demonstrated using a separable, classically correlated two-copy input state, showing that classical correlations alone are sufficient to produce the reliability gain. This finding highlights an unexpected role for correlations beyond entanglement in quantum communication protocols. Rather than increasing the amount of information that can ultimately be transmitted, the work shows that correlated channel use mak

WarpSpeed Says its AI cuts quantum encryption cracking cost sharply

WarpSpeed’s artificial intelligence has designed a quantum circuit that cracks a standard cryptographic challenge with significantly improved efficiency, the company says. The system achieved a 2.5 times more efficient circuit than Google’s in cracking the ECDSA challenge, a benchmark used to assess the security of digital signatures underpinning cryptocurrencies like Bitcoin and Ethereum, according to WarpSpeed. This improvement exceeds the median improvement on the benchmark over the last month by about two and a half orders of magnitude; according to WarpSpeed, its circuit consists of only 993,181 Toffoli gates and 1,205 qubits, certified by a zero-knowledge proof. Beyond circuit design, the company’s agents also found gaps combining cryptography, performance engineering, and software security within the benchmark’s verification processes, the firm reports. WarpSpeed AI Achieves 2.5x Efficiency in ECDSA Cracking WarpSpeed’s artificial intelligence delivered a quantum circuit that reduces the computational cost of cracking the Elliptic Curve Digital Signature Algorithm (ECDSA) by a substantial margin, achieving a 2.5 times more efficient circuit than Google Quantum AI’s previously published designs, WarpSpeed claims. This leap in performance was demonstrated on the publicly available ecdsa.fail benchmark, which Eigen Labs created from the Google paper. The system achieved these results through self-improvement, by the company’s account. The core of the challenge revolves around efficiently calculating point addition on elliptic curves, a fundamental operation within the ECDSA cryptographic scheme. Shor’s algorithm, the quantum method used to break this encryption, relies heavily on the cost of this single operation; therefore, optimizing point addition directly impacts the overall attack complexity.

DARPA funds Qunnect to improve quantum signal correction in fiber

Qunnect is the first company to anchor multiple quantum networks, currently distributing quantum information across telecom fiber in New York, Bozeman, Berlin, and Albuquerque. The Defense Advanced Research Projects Agency is now funding Qunnect to further develop its Carina rack, described as the “first commercially available turnkey quantum entanglement distribution system.” Carina addresses the fragility of quantum entanglement over existing telecommunications networks by continuously correcting for signal corruption. “We made an early commitment to designing instruments that operate on the same infrastructure the world already uses,” said Noel Goddard, CEO of Qunnect, as the company expands its reach to two continents through partnerships with Montana State University and Deutsche Telekom. Carina System Anchors Quantum Networks Across Telecom Fiber Qunnect currently anchors quantum networks spanning two continents, a feat previously unattained in the field of quantum entanglement distribution. This deployment is not limited to laboratory settings; Qunnect is actively utilizing established networks, a strategic decision highlighted by CEO Noel Goddard, who said that real-world fiber optic cables introduce environmental noise that degrades quantum signals, unlike classical data which is more resilient. Carina functions by actively counteracting polarization drift, essentially acting as a corrective measure for entangled photons. This proactive correction is vital for maintaining the fragile quantum states necessary for secure communication and advanced computation. Qunnect’s advancement is gaining recognition as essential infrastructure, with Chief Science Officer Mehdi Namazzi stating, “Global governments increasingly view quantum networking as critical infrastructure.” The company’s head start in deploying functional networks, rather than remaining in the theoretical stage, positions it as a key partner for organizations seeking to build future communications sy
