The first quantum computer has arrived. The version of a quantum chip that recently came out of the Niels Bohr Institute in Copenhagen is now for sale, but it has already been sold out.

The price is cheap according to professor Peter Lodahl from Sparrow Quantum who has recently moved out of the old Niels Bohr Institute to the other side of the street. Not a big move but a quantum leap.

Science journalist Jens Degett is talking to Peter Lodahl in this podcast trying to understand what a quantum computer can do, how it works and what purpose it will serve.
