In Pursuit of Qubits, Uniting Subatomic Particles By the Billions

In a step toward a generation of ultrafast computers, physicists have used bursts of radio waves to briefly create 10 billion quantum-entangled pairs of subatomic particles in silicon. The research offers a glimpse of a future computing world in which individual atomic nuclei store and retrieve data and single electrons shuttle it back and forth.

In a paper published this week in the journal Nature, a team led by the physicists John Morton of Oxford University and Kohei Itoh of Keio University describes an experiment in which they bombard a three-dimensional crystal with microwave and radio frequency pulses to create the entangled pairs.

This is one of a range of competing approaches to making qubits, the quantum computing equivalent of today’s transistors.
