A formula used to turn ordinary data, or "plaintext," into a secret coded message known as "ciphertext." The ciphertext can reside in storage or travel over unsecure networks without its contents ...

People have performed many mathematical proofs to show that a quantum computer will vastly outperform traditional computers on a number of algorithms. But the quantum ...

A quantum computer algorithm that is used to find the prime factors in an encryption key. Created by applied mathematician Peter Shor in the mid-1990s, Shor's algorithm may be used to break the codes ...

Computer programmers have developed a new 'cutting-plane' algorithm, a general-purpose algorithm for solving optimization problems. The algorithm improves on the running time of its most efficient ...
