Spreading light over quantum computers

Scientists at Linköping University have shown how a quantum computer really works and have managed to simulate quantum computer properties in a classical computer. "Our results should be highly significant in determining ...

Toward an 'orrery' for quantum gauge theory

Physicists at ETH Zurich have developed a new approach to couple quantized gauge fields to ultracold matter. The method might be the basis for a versatile platform to tackle problems ranging from condensed-matter to high-energy ...

A single-photon source you can make with household bleach

Quantum computing and quantum cryptography are expected to give much higher capabilities than their classical counterparts. For example, the computation power in a quantum system may grow at a double exponential rate instead ...

Is your supercomputer stumped? There may be a quantum solution

Some math problems are so complicated that they can bog down even the world's most powerful supercomputers. But a wild new frontier in computing that applies the rules of the quantum realm offers a different approach.
