It’s been difficult to find important questions that quantum computers can answer faster than classical machines, but a new ...

Next, we will study algorithms for NP-hard problems whose solutions are guaranteed to be within some approximation factor of the best possible solutions. Such algorithms are often quite efficient and ...

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 ...

Algorithms are the building blocks that, when layered together, form the cryptographic fortress that keeps out hackers. As quantum computers gain ascendancy, these bricks must change to keep our ...

Quantum computers promise to speed calculations dramatically in some key areas such as computational chemistry and high-speed networking. But they're so different from today's computers that ...

Several groups of scientists are racing to develop cryptographic algorithms that can evade hacking by quantum computers before they are rolled out. Some of these cryptographic algorithms rely on ...

An algorithm is a clear sequence of instructions with a start, a finish, and usually some decisions in the middle. They can be expressed in a flow chart. The computer only makes mistakes if there ...
