Physicists show that the loss of energy from a quantum system, usually a problem, can be harnessed to create lasting entanglement between distant qubits.

The race to shield crypto from quantum attacks shifts from theory to engineering, as a Reuters report shows exchanges integrating post-quantum cryptography faster than governments.

Experiment in diamond demonstrates how the smallest unit of sound can control a quantum bit, paving the way for sound-based quantum technologies and precision sensors.

Researchers propose a charge-neutral helium-3 oscillator that may resist electrical noise, with far lower predicted error rates than superconducting qubits.

A 0.5B-parameter neural tensor-network pre-trained on hundreds of thousands of Hamiltonians generalizes to arbitrary systems—scaling to 8100 qubits.
