Quantum data takes a ride on sound waves

Yale scientists have created a simple-to-produce device that uses sound waves to store quantum information and convert it from one form to another, all inside a single, integrated chip.

The device allows a superconducting artificial atom — a qubit — to exchange energy and quantum information with a high frequency bulk acoustic wave resonator (HBAR). The ability to manipulate and store fragile quantum data in a robust and easy-to-manufacture way is a crucial step in the development of quantum computing technology.

The work is a collaboration at Yale between the labs of Robert Schoelkopf, the Sterling Professor of Applied Physics and Physics, and Peter Rakich, assistant professor of physics. Yiwen Chu, a postdoctoral associate in Schoelkopf’s lab, led the effort and is first author of a study that appears Sept. 21 in the online edition of the journal Science. Read more
