Two analyses suggest that quantum computers could crack ubiquitous security keys and cryptocurrencies before the decade is over.

Traditional encryption methods have long been vulnerable to quantum computers, but two new analyses suggest a capable enough machine may be built much sooner than previously thought

Quantum computers of the future may be closer to reality thanks to new research from Caltech and Oratomic, a Caltech-linked start-up company. Theorists and experimentalists teamed up to develop a new approach for reducing the errors that riddle today's rudimentary quantum computers.

Charles Bennett and Gilles Brassard were recognized for their foundational work in quantum information science.
