Harvest Now, Decrypt Later: Why the Quantum Cybersecurity Threat Has Already Begun

A cryptographically powerful quantum computer does not yet exist, but sensitive encrypted information may already be under threat. The “harvest now, decrypt later” strategy allows adversaries to collect protected data today and wait for future quantum systems to break the encryption, making post-quantum migration an immediate cybersecurity priority.

Top 10 Quantum Computing Companies in the United Kingdom — Ranked by QuantumNews

The United Kingdom has become one of the most interesting quantum ecosystems to watch because its companies are not all trying to solve the same problem. Some are building quantum processors. Some are working on photonic systems. Some are focused on trapped ions, superconducting qubits, silicon spin qubits, quantum networking, quantum-safe encryption, and quantum sensing. That diversity matters because the quantum industry will not be built by one technology path alone. It will be shaped by hardware breakthroughs, software infrastructure, secure communications, error correction, quantum networking, and industry-ready deployment models

IonQ vs. Rigetti Computing: Which Pure-Play Quantum Stock Actually Has the Technology Edge? - The Motley Foolquantum-computing

IonQ vs. Rigetti Computing: Which Pure-Play Quantum Stock Actually Has the Technology Edge? - The Motley Fool

IonQ (IONQ -1.20%) and Rigetti Computing (RGTI -1.18%) are taking entirely different technological routes in their efforts to build useful quantum computers. IonQ uses trapped-ion technology, where individual charged atoms held in place by precise electromagnetic fields serve as qubits, the basic units of information in any quantum computer. Rigetti Computing uses superconducting qubits, which are tiny electrical circuits cooled to extremely low temperatures. Image source: Getty Images. IonQ has demonstrated more than 99.99% fidelity, or accuracy, for 2-qubit gates (operations performed on 2 qubits at the same time). Rigetti Computing has reported roughly 99.1% median 2-qubit fidelity on its 108-qubit Cepheus system. Hence, its typical 2-qubit operation succeeds about 99.1% of the time.  While IonQ may appear to be the obvious technology winner, these figures are not directly comparable. IonQ's 99.99% result came from testing a particular 2-qubit operation, rather than measuring the overall performance of a large commercial quantum computer. A more comparable measure comes from IonQ's Forte systems, which have reported a median 2-qubit fidelity of 99.3% to 99.5%. Hence, although IonQ's qubits still appear to perform operations more accurately than Rigetti Computing's, the gap in accuracy between them is much smaller. IonQ's quantum computing technology That narrower accuracy gap could prove crucial when quantum calculations become more complex. Using the more comparable figures above, 99.5% fidelity implies an error rate of roughly 0.5%, compared with about 0.9% at 99.1%. Hence, Rigetti Computing's error rate is roughly 1.8 times as high in this comparison.

I built a Grover’s Algorithm simulator and ran it on IBM hardware to understand it better (Linear Algebra-based explanation)quantum-computing

I built a Grover’s Algorithm simulator and ran it on IBM hardware to understand it better (Linear Algebra-based explanation)

Hey everyone, After watching some videos on Grover’s algorithm, I was still struggling to grasp how it actually works under the hood. Since I don't have a deep background in physics, I decided to build and explain it myself purely through linear algebra (state vectors and matrices). I put together a GitHub repo aiming to build intuition for software engineers without the physics jargon. To make it practical, I also built a Qiskit simulator to visualize the theoretical scaling, and ran the same circuits on IBM quantum hardware to see where the physical decoherence cliff hits. I've attached the result graphs to this post. I'm definitely not a professor:) just a student trying to organize these concepts in my head. This project is kind of prep for future academic papers and work, so if any experts here have the time to skim the logic, I would highly appreciate any feedback, corrections, or critiques. (Feel free to comment here or open an Issue on the GitHub). submitted by /u/Puzzleheaded-Bee4566 [link] [comments]

ParityQC’s new optimizer cuts gate count for quantum problemsquantum-computing

ParityQC’s new optimizer cuts gate count for quantum problems

IBM Quantum Network members can now test a new optimization tool with a 30-day free trial. ParityQC has launched the Parity Twine Optimizer within the IBM Qiskit Functions Catalog, bringing its record-setting compiler technology, originally demonstrated with the Quantum Fourier Transform, to a wider audience, the company says. The optimizer reduces two-qubit gate overhead, enabling the execution of larger, denser optimization problems on current quantum hardware. “By offering the Parity Twine Optimizer as an IBM Qiskit Function, we are providing the quantum community with access to a tool with what we currently show to be the most efficient quantum compiler available for larger and more connected problems to run on real hardware,” say ParityQC co-CEOs Magdalena Hauser and Wolfgang Lechner. Parity Twine Optimizer Reduces Gate Count for Quantum Optimization The Parity Twine Optimizer delivers a significant reduction in gate count and depth for quantum optimization, enabling the execution of denser problems on current hardware. Initial results demonstrate the technology minimizes two-qubit gate overhead when compiling industry-relevant optimization challenges, a benefit stemming from the structure of Parity encoding itself and maintaining consistency as problems scale. This hardware-independent compiler, also available through ParityQC’s ParityOS software, expands access beyond IBM’s platform with future integrations planned. The technology eliminates the need for costly SWAP operations, allowing full use of existing quantum processors by minimizing circuit depth and two-qubit gate overhead. ParityQC, founded in 2020 and headquartered in Innsbruck, Austria, designs hardware-efficient quantum optimization algorithms using parity-encoded quantum circuits. Partnerships with companies like Classiq and NEC demonstrate a commitment to broader integration; Classiq is combining efforts to reduce quantum circuit complexity, while NEC implemented ParityQC’s architecture in its q
