How a quantum computer really works

Researchers at Linköping University have shown how a quantum computer really works and have managed to simulate quantum computer properties in a classical computer.

We have shown that the major difference is that quantum computers have two degrees of freedom for each bit. By simulating an additional degree of freedom in a classical computer, we can run some of the algorithms at the same speed as they would achieve in a quantum computer”, says Professor Jan-Åke Larsson.

They have also supplemented their theoretical simulations with a physical version built with electronic components. (Linköping University)
