Quantum Computers

The one thing everyone knows about quantum mechanics is its legendary weirdness, in which the basic tenets of the world it describes seem alien to the world we live in.

The prototype of the memcomputer, which works by mimicking the human brain, could one day lead to computers that solve notoriously difficult math problems and could even help to break codes.

Building a quantum computer can sometimes yield unexpected benefits — like providing the right environment to demonstrate that Albert Einstein's theory of special relativity is, in fact, correct.

Quantum dot masers could help develop quantum computers and probe the mysteries of entanglement.

A new particle detector has made it possible to generate three entangled photons that could be used in quantum telecommunication.

Researchers developed a technique to calculate quantum wave functions 350 times faster than previous methods.

The world's first commercial quantum computer, made by the Canadian company D-Wave Systems Inc., performed no better than a classical computer in a recent analysis.

Researchers have directly measured a photon's 27-dimensional quantum state, which could make it simpler to build quantum-mechanical technologies such as quantum computers and unbreakable codes.
