Quantum Computing

A team at the Technion in Israel has confirmed something theorists predicted in 1978: points of absolute darkness within light waves can travel faster than light itself.

Google said on March 26 that quantum computers could break the RSA-2048 encryption protecting much of the internet by 2029.

For years, photonic quantum computing has been stuck at two modes.

Western Digital has been quietly building a quantum portfolio, and Thursday's announcement that its research arm is joining an open-source error correction working group makes the strategy harder to ignore.

A team of physicists at the University of Vienna has demonstrated, with 18 standard deviations of statistical significance, that the notion of events happening in a fixed sequence — A then B, or B then A — may be a classical assumption the universe does not share.

A team at the Shenzhen International Quantum Academy has demonstrated multi-qubit entanglement using a superconducting processor built from dual-rail erasure qubits — an architecture that treats the dominant error type in superconducting systems as detectable rather than invisible.

IBM published a blog post this week calling it "the most impressive match" between a quantum simulation and real experimental data — a quantum computer's recreation of the energy spectrum of a magnetic material called KCuF3, checked against actual neutron scattering measurements from two national...

Fujitsu and the University of Osaka have published two papers suggesting that quantum chemistry simulations for industrially relevant molecules could be tractable with roughly 100,000 physical qubits — not the millions the field has long treated as the entry fee for useful quantum computation. T...

A team at Argonne National Laboratory has demonstrated that a single material can switch between two fundamentally different electronic states — and the switch is reversible, controlled by an electrical current.

Making a single-photon emitter in a 2D semiconductor is not the hard part.

Google Quantum AI is doing something it rarely does: hedging twice.
