A diamond’s quantum memory sets a glittering record

Tiny device holds an unprecedented number of quantum units of information.

Quantum memories built of ‘qubits’, the quantum equivalent of computer bits, could make possible technologies from ultra-secure communication systems to quantum computers far faster than today’s machines. Now physicists have created a diamond-based quantum memory that holds 10 qubits and stores information for 75 seconds — both records for such a device.
