A fault-tolerant system for stopping ‘leaks’ in quantum computers

Yale researchers have designed a new system to keep tomorrow’s quantum computers from “leaking.” 

Large-scale quantum computers are still years away, but it is well known that they will need error correction. All of the components in a quantum computer are connected in a fragile, entangled state that allows a quantum computer to solve problems that would be impossible on a classical computer. Because of this entanglement, an error in just one bit of quantum information, called a qubit — or even the act of measuring a qubit — can collapse the entire enterprise.
