CAMBRIDGE, MA — The most recent email you sent was likely encrypted using a tried-and-true method that relies on the idea that even the fastest computer would be unable to efficiently break a gigantic ...

SAN JOSE, Calif., — Scientists at IBM’s Almaden Research Center have performed the world’s most complicated quantum-computer calculation to date. They caused a billion billion custom-designed ...

In 1994, Peter Shor, an American mathematician working at Bell Labs, published a paper with a wonky title and earth-shaking implications. In “Polynomial-Time Algorithms for Prime Factorization and ...

Childs has been recognised for his contributions to quantum simulation and Hamiltonian dynamics. His work has focused on developing fast quantum algorithms for simulating Hamiltonian dynamics, which ...

After decades of theory, prototypes, and incremental progress, quantum computing has entered a new era… The story began in earnest in the early 1980s, when Richard Feynman and Yuri Manin argued that ...

QKD uses photons — the smallest units of light — to securely transmit encryption keys. Any attempt to intercept them disturbs their quantum state, alerting the sender and receiver. This makes QKD ...

One of the most well-established and disruptive uses for a future quantum computer is the ability to crack encryption. A new algorithm could significantly lower the barrier to achieving this. Despite ...
