This 250-year-old equation just got a quantum makeover

A team of international physicists has brought Bayes’ centuries-old probability rule into the quantum world. By applying the “principle of minimum change” — updating beliefs as little as possible while remaining consistent with new data — they derived a quantum version of Bayes’ rule from first principles. Their work connects quantum fidelity (a measure of […] more…

Quantum simulations that once needed supercomputers now run on laptops

A team at the University at Buffalo has made it possible to simulate complex quantum systems without needing a supercomputer. By expanding the truncated Wigner approximation, they’ve created an accessible, efficient way to model real-world quantum behavior. Their method translates dense equations into a ready-to-use format that runs on ordinary computers. It could transform how […] more…

Physicists just built a quantum lie detector. It works

An international team has confirmed that large quantum systems really do obey quantum mechanics. Using Bell’s test across 73 qubits, they proved the presence of genuine quantum correlations that can’t be explained classically. Their results show quantum computers are not just bigger, but more authentically quantum. This opens the door to more secure communication and […] more…

Quantum chips just proved they’re ready for the real world

Diraq has shown that its silicon-based quantum chips can maintain world-class accuracy even when mass-produced in semiconductor foundries. Achieving over 99% fidelity in two-qubit operations, the breakthrough clears a major hurdle toward utility-scale quantum computing. Silicon’s compatibility with existing chipmaking processes means building powerful quantum processors could become both cost-effective and scalable. more…

Mysterious “quantum echo” in superconductors could unlock new tech

Google’s quantum computer creates exotic state once thought impossible

Physicists have achieved a breakthrough by using a 58-qubit quantum computer to create and observe a long-theorized but never-before-seen quantum phase of matter: a Floquet topologically ordered state.

A hidden quantum geometry that distorts electron paths has finally been observed in real materials. This “quantum metric,” once thought purely theoretical, may revolutionize electronics, superconductivity, and ultrafast devices. more…

Strange “heavy” electrons could be the future of quantum computing

Scientists in Japan have uncovered a strange new behavior in “heavy” electrons — particles that act as if they carry far more mass than usual. These electrons were found to be entangled, sharing a deep quantum link, and doing so in ways tied to the fastest possible time in physics. Even more surprising, the effect […] more…
