Scientists have used the famed "Schrödinger's cat" thought experiment to come up with a way to remove errors from future quantum computers. The new method encodes quantum information onto an ...

He imagined a box containing a radioactive atom, a vial of poison and a cat. Governed by quantum rules, the radioactive atom can either decay or not at any given moment. There’s no telling when ...

The authors demonstrate a superconducting quantum circuit device using an array of cat qubits, where errors are shown to be suppressed from 1.75% per cycle to 1.65% for an error-correcting code ...
