摘要

Techniques for operating a mechanical oscillator as a quantum memory are described. According to some aspects, a qubit may be coupled to a piezoelectric material such that the electric field of the qubit causes stress within the piezoelectric material. The piezoelectric material may be in contact with a crystalline substrate forming an acoustic resonator such that the qubit couples to bulk acoustic waves in the crystalline substrate via its interaction with the piezoelectric material. According to some aspects, application of a suitable electromagnetic pulse to the qubit may cause an exchange of energy from the qubit to the acoustic phonon system and thereby transfer quantum information from the qubit to the phonon system.
