Conical two-designs slash quantum entanglement verification costs. New math boosts QKD security for banks as live 4-month financial network deployment proves real.

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

A new silicon-based nanostructure keeps fragile quantum information alive at room temperature, achieving a record performance that could accelerate future quantum computers and ultra-secure communications.

Quantum computers have passed a mathematically proven test that no classical computer can ever pass, demonstrating an unconditional quantum advantage for the first time.

Breuckmann, Golowich and Vazirani prove quantum circuits can survive an adversary corrupting an almost-linear number of qudits at every time step.
