quantum-computingQuEra Outlines 2028 Roadmap for 256-Logical-Qubit “Libra” System and Expanded AWS Cloud Partnership
QuEra Outlines 2028 Roadmap for 256-Logical-Qubit “Libra” System and Expanded AWS Cloud Partnership Neutral-atom hardware developer QuEra Computing and Amazon Web Services (AWS) have announced an expanded, multi-year strategic collaboration to bring the first fault-tolerant quantum computer to the cloud. Scheduled for release in 2028, QuEra’s upcoming system, Libra, is designed as a “megaquop-class” processor. This classification indicates that the hardware is engineered to execute on the order of one million reliable logical quantum operations over hundreds of logical qubits before computational states are degraded by errors. Under the expanded agreement, the error-corrected system will be hosted natively on Amazon Braket, establishing an integration pathway for early non-trivial research and scientific applications. Technical Parameters: Target Specs and Reconfigurable Atom Arrays The structural architecture of the Libra processor targets an operational baseline of 256 error-corrected logical qubits and an anticipated logical error rate of 10-6 (one error per million operations). To sustain these thresholds, the system utilizes neutral-atom (Rydberg) technology, which inherently scales by organizing thousands of identical atoms within a single module, eliminating the need for complex inter-module interconnects. Furthermore, the hardware leverages optical tweezers—highly focused laser beams—to dynamically reposition atoms in real time without destroying quantum coherence. This reconfigurability provides all-to-all connectivity between qubits, allowing the system to run ultra-high-rate, transversal error-correcting codes that lower the physical-to-logical qubit overhead ratio compared to rigid, static topologies. Peer-Reviewed Scientific Foundations and Validation History The engineering roadmap for Libra builds on a series of field validations conducted by QuEra and its academic founders at Harvard University and the Massachusetts Institute of Technology (MIT).

quantum-computingTight Bounds for Quantum Phase Estimation and Related Problems
AbstractPhase estimation, due to Kitaev [17], is one of the most fundamental subroutines in quantum computing. In the basic scenario, one is given black-box access to a unitary $U$, and an eigenstate $\lvert \psi \rangle$ of $U$ with unknown eigenvalue $e^{i\theta}$, and the task is to estimate the eigenphase $\theta$ within $\pm\delta$, with high probability. The cost of an algorithm for us is the number of applications of $U$ and $U^{-1}$. We tightly characterize the cost of several variants of phase estimation where we are no longer given an eigenstate, but are required to estimate the maximum eigenphase of $U$, aided by advice in the form of states (or a unitary preparing those states) which are promised to have at least a certain overlap $\gamma$ with the top eigenspace. We give algorithms and nearly matching lower bounds for all ranges of parameters. We show that a small number of copies of the advice state (or of an advice-preparing unitary) are not significantly better than having no advice at all. We also show that having lots of advice (applications of the advice-preparing unitary) does not significantly reduce cost, and neither does knowledge of the eigenbasis of $U$. We immediately obtain a lower bound on the complexity of the Unitary recurrence time problem, resolving an open question of She and Yuen [29]. Lastly, we study how efficiently one can reduce the error probability in the basic phase-estimation scenario. We show that a phase-estimation algorithm with precision $\delta$ and error probability $\epsilon$ has cost $\Omega\left(\frac{1}{\delta}\log\frac{1}{\epsilon}\right)$, matching an easy upper bound. This contrasts with some other scenarios in quantum computing (e.g., search) where error-probability reduction costs only a factor $O(\sqrt{\log(1/\epsilon)})$. Our lower bound uses a variant of the polynomial method with trigonometric polynomials.► BibTeX data@article{Mande2026tightboundsquantum, doi = {10.22331/q-2026-06-15-2140}, url = {https://

quantum-computingCHIRON Project Launches Quantum Communication Network Initiative in Germany
Insider Brief The CHIRON project has launched in Germany to develop a scalable quantum communication infrastructure based on entanglement-enabled Quantum Key Distribution (QKD). The consortium will demonstrate quantum-secure networking through testbeds in Berlin and Thuringia, integrating quantum communications with existing digital infrastructure. The project combines entangled photon sources, quantum networking technologies, secure operating systems, and intelligent key routing to support future quantum-secure communications. PRESS RELEASE — The CHIRON project has officially launched, bringing together leading German research institutions and technology companies to build a scalable, entanglement-based quantum communication infrastructure designed to secure Europe’s digital networks against emerging cyber threats. Encryption protecting today’s digital infrastructure is under existential pressure from accelerating computing power, AI-driven attacks, and the approaching reality of cryptographically relevant quantum computers. While post-quantum cryptography (PQC) will strengthen algorithmic resilience, only Quantum Key Distribution (QKD) can provide long-term protection against “harvest now, decrypt later” attacks. Quantum Optics Jena will play a central role in making that vision a reality. Within CHIRON, the company is building the long-distance quantum communication backbone through SPAD-based polarization-entanglement links and high-brightness, high-heralding photon sources. These technologies are designed to extend the reach of semiconductor-detector-based QKD systems and create a scalable, maintainable network capable of connecting users across large geographic areas. The BMFTR-funded consortium will demonstrate the network across two real-world testbeds in urban Berlin and rural Thuringia, integrating quantum communications into existing ICT infrastructure. The project will also test quantum-secured access tokens at Bundesdruckerei for users operating in

quantum-computingTemporal Coarse Graining for Classical Stochastic Noise in Quantum Systems
AbstractSimulations of quantum systems with Hamiltonian classical stochastic noise can be challenging when the noise exhibits temporal correlations over a multitude of time scales, such as for $1/f$ noise in solid-state quantum information processors. Here we present an approach for simulating Hamiltonian classical stochastic noise that performs temporal coarse-graining by effectively integrating out the high-frequency components of the noise. We focus on the case where the stochastic noise can be expressed as a sum of Ornstein-Uhlenbeck processes. Temporal coarse-graining is then achieved by conditioning the stochastic process on a coarse realization of the noise, expressing the conditioned stochastic process in terms of a sum of smooth, deterministic functions and bridge processes with boundaries fixed at zero, and performing the ensemble average over the bridge processes. For Ornstein-Uhlenbeck processes, the deterministic components capture all dependence on the coarse realization, and the stochastic bridge processes are not only independent but taken from the same distribution with correlators that can be expressed analytically, allowing the associated noise propagators to be precomputed once for all simulations. This combination of noise trajectories on a coarse time grid and ensemble averaging over bridge processes has practical advantages, such as a simple concatenation rule, that we highlight with numerical examples.Popular summaryClassical simulation of quantum systems is a valuable tool for understanding the role of different noise sources on a quantum system's behavior, as well as informing how different strategies can mitigate or eliminate the impact of such non-idealities. For this reason, the development of practical methods that allow a more faithful simulation of the noise experienced by a quantum system remains an important area of research. Many noise sources, such as charge noise in solid-state quantum technologies, exhibit temporal correlations
