A few updates: 1. The BBC got in touch last week to ask if I'd look at a press release and embargoed preprint on quantum computing to give some expert commentary.  The work turned out to be from Microsoft, claiming another breakthrough in their desire to fabricate functional majorana qubits.  The preprint shows their "multi-qubit" tetron device, with signals coming from its operation.  What was n…

Modern quantum circuit simulation is not just “machine learning with complex tensors.” It involves irregular tensor contractions, sparse operators, statevector transformations, and automatic differentiation through all of them. This makes backend choice unusually important. A backend that is excellent for standard neural-network layers may still be a poor fit for general quantum simulation worklo…

When certain sensors are exposed to light, they produce a photocurrent. But using such information limits speed and power efficiency. Researchers developed sensors called spectral kernel machines that convert a photocurrent into object and chemical identification without additional processing.

A Forbes Council expert highlights that the convergence of quantum computing and Artificial Intelligence (AI) is poised to transform risk management across industries — not just in finance and insurance, but in any field where uncertainty and complexity prevail. Quantum Read More ... The post Reengineering risk management in the quantum‑AI era first appeared on Risk Management Association of Indi…

With Texas quickly becoming a global hub for quantum innovation, Gov. Greg Abbott has appointed Jeff Prevost, PhD, executive director of UT San Antonio’s Open Cloud Institute, to the newly established Texas Quantum Initiative Advisory Committee. The appointment highlights the university’s pivotal role in Texas’ rise as a leader in quantum computing. Quantum computing is […] The post Governor Abbo…

Qisquiz: A Quiz App for Learning Qiskit v2.X I recently built Qisquiz , a quiz-based learning app for people studying Qiskit v2.X and preparing for the IBM Certified Quantum Computation using Qiskit v2.X Developer exam. You can try the app here: https://qisquiz.vercel.app/ GitHub repository: https://github.com/dorakingx/qisquiz Qisquiz is still in an early version, but the goal is simple: Master …

Tang’s dequantisation programme established that several quantum machine learning algorithms admit efficient classical simulation when given ℓ2-norm sample-and-query (SQ) access to their input data. The specific choice of ℓ2-norm sampling—rather than uniform, ℓ1, or any other sampling rule—has hitherto been justified operationally by its polynomial-time implementability, but not axiomatically. We…

The Majorana 2 quantum processor is built from topological qubits, and its creators claim it can sustain quantum coherence for an average of 20 seconds — orders of magnitude longer than the milliseconds that conventional chips last.

Quantinuum, a quantum computing startup, is losing millions. Investors want in anyway.

Science and indeed society are entering a new era shaped by quantum technologies and artificial intelligence. #LINO26 will explore how these technologies are reshaping both knowledge and the meaning of understanding itself. Der Beitrag Quantum Technologies and Artificial Intelligence: Shaking the Very Foundations of Science erschien zuerst auf Lindau Nobel Laureate Meetings .

IBM and educational partners outlined which quantum advancements excite them and explained why it’s never too early to get on board.

Some quantum computing companies we've covered have done recent progress updates.

It's been a while that quantum computing is looked as the next step in computational science. I somewhat always tought we were decade aways from it's happening but it appears I was wrong: ibm-quantum-computing-cloud (well, I am still not sure this is a large scale quantum computer or an efficient quantum computer replication; edit: changed the link; it is a simulator) Quantum mechanics and quanti…

More than 20 organizations are participating, including multinational corporations in autos, chemicals and other industries, as well as RIKEN and several prestigious Japanese universities. The post Qunova Joins JHPC-quantum Test User Program in Japan appeared first on Semiconductor Digest .

Nature, Published online: 03 June 2026; doi:10.1038/s41586-026-10517-4 A Mamyshev oscillator mode-locked laser compactly integrated on a photonic-chip delivers nanojoule, femtosecond pulses.

Let’s Encrypt is committed to a post-quantum-safe Web PKI. The path we’re planning to take is Merkle Tree Certificates (“MTCs”), a new approach that adds post-quantum authentication to the web without sacrificing the speed and reliability that have made TLS universal. This post is about these plans and why we believe MTCs are worth pursuing as a key to a post-quantum future. For much of the last …

A quantum computer made from extremely cold atoms can correct its own errors during long computations, an important prerequisite for becoming truly useful

IntroductionElectronic health records (EHRs) increasingly anchor clinical decision support and population-scale analytics, yet their concentration of sensitive information amplifies disclosure risk, widens the attack surface, and faces emerging threats from quantum computing. Existing frameworks fail to simultaneously address privacy preservation, quantum-resistant security, and cross-institution…
