Yale couples a superconducting qubit to a single microwave photon

Jul 13, 2004

Andreas Wallraff and colleagues at Yale strongly couple a superconducting qubit to a microwave photon trapped in a resonator on a chip. The experiment lets them observe a controlled interaction between the artificial atom and light.

Why it matters

Controlling interactions between qubits and microwave resonators provides a building block for processing and communicating quantum information on chips.
