Quantum Challenge Solved Underground

Radiation from space is a challenge for quantum computers as their computation time becomes limited by cosmic rays. Researchers from Chalmers University of Technology, Sweden, and University of Waterloo in Canada are now going deep underground in the search for a solution to this problem—in a two-kilometer-deep mine.

A recently discovered cause of errors in quantum computers is cosmic radiation. Highly charged particles from space disturb the sensitive qubits and cause them to lose their quantum state, as well as the ability to continue a calculation. 

But now quantum researchers from Sweden and Canada will join forces to find a solution to the problem—in the world's deepest located clean room, two kilometers underground.  READ MORE...
