QuiX Quantum achieves first below‑threshold error mitigation on photonic processor
QuiX Quantum reported a breakthrough on its 20‑mode photonic quantum computer, reducing photon‑indistinguishability error by 2.2× and lowering overall system error by 1.2×. The result was demonstrated using a photon‑distillation gate in collaboration with NASA’s Quantum AI Lab, the University of Twente and Freie Universität Berlin.

By the numbers: Monarch Quantum raises $55M Series A
A team at Israel's Technion, headed by Dr. Michael Krüger, directly measured the duration of individual bright squeezed vacuum (BSV) light pulses at 27.2 femtoseconds, confirming their ultrafast nature and revealing a random π‑phase distribution. The result clears a long‑standing experimental gap and paves the way for faster photonic quantum processors and high‑speed quantum links.
University of Sydney physicists announced a new quantum error‑correction technique that could slash the number of physical qubits required for large‑scale, fault‑tolerant quantum processors. The method, based on gauge theory, has already been incorporated into IBM’s roadmap, offering a tangible...
IonQ Inc. projected 2026 revenue of $225‑$245 million, citing a growing customer base, an expanded product portfolio and a $370 million backlog. The outlook reflects the company’s strong cash position and its push toward a 256‑qubit system as the quantum computing market...
Scientists at Australia’s CSIRO and RMIT University have built a quantum battery whose charging time shrinks as the device gets larger, overturning the classic trade‑off between size and speed. The prototype uses collective light‑matter interactions to achieve femtosecond charging and...
A new preprint introduces a machine‑learning framework that maps entropy‑vector dynamics to identify quantum states violating Ingleton’s inequality, a boundary respected by stabilizer and holographic states. The authors prove pure‑state violations are impossible for five qubits or fewer, establishing six...
There has been extensive discussion about how many qubits are required for a fault-tolerant #quantumcomputer capable of demonstrating quantum utility. However, we should not overlook the fact that, for now, available quantum computers are not fully error-corrected. How far can...
The first quantum computer to break encryption is now shockingly close | New Scientist https://t.co/HsfzVRqn1R
Monarch Quantum announced a $55 million Series A round to scale its integrated photonics infrastructure for quantum technologies. The round was led by Serendipity Capital with participation from 55 North and Global Innovation Labs. The funding will support engineering, manufacturing,...
The video examines the latest claim from Microsoft that it has finally tamed the elusive Majorana fermion to build topological qubits, a development it says could unlock practical quantum computers as early as 2025. It explains how quantum computers differ from...
QuiX Quantum announced the first below‑threshold error mitigation on a photonic quantum computer, using a 20‑mode processor and a photon‑distillation gate. The technique achieved a 2.2× reduction in photon‑indistinguishability error and a net 1.2× overall system‑error decrease. Collaborators include NASA’s...
Quantum Elements and Amazon Web Services have launched Constellation, a cloud‑based digital‑twin platform that lets researchers model quantum error‑correction schemes on hypothetical quantum computers. The tool improves on existing simulators by capturing a broader range of error sources, offering higher...
A team at Canada’s Institut national de la recherche scientifique (INRS) unveiled a Talbot‑array‑based method that isolates quantum photon signals from heavy optical background, raising the coincidence‑to‑accidental ratio from 2.2 to 21.3. The breakthrough promises more robust quantum communication and...
The U.S. Intelligence Community Just Put Quantum on Equal Footing with AI. And Expanded the Threat Definition https://t.co/BFmWJ9pOmy via @infosec
Google’s Quantum AI team published a whitepaper revealing that breaking Bitcoin’s cryptography may require only 1,200‑1,450 high‑quality qubits, a dramatic reduction from earlier estimates of millions. The finding accelerates concerns over quantum‑resistant cryptography and could reshape the crypto‑security roadmap.
Patent activity in quantum computing is accelerating as the sector moves toward commercial products. Recent PTAB rulings reveal that many quantum‑related applications encounter the same eligibility and claim‑drafting hurdles seen in software patents, but amplified by the field’s reliance on...
Researchers at Purdue University and Menlo Microsystems have shown that commercial RF MEMS SP4T switches can function reliably at cryogenic temperatures as low as 5.8 K. The switches exhibit sub‑0.5 dB insertion loss, over 35 dB isolation, and a 15 % reduction in on‑resistance...
Regarding the Quantum threat to Bitcoin: It's not a question of if, it's a question of when. And if when is being pulled closer by best estimates, then it's common sense to start discussing solutions. That's not FUD or hysterics,...
