Testing spontaneous wavefunction collapse with quantum electromechanics

  title={Testing spontaneous wavefunction collapse with quantum electromechanics},
  author={Germain Tobar and Stefan Forstner and Arkady Federov and Warwick P. Bowen},
Theories of spontaneous wavefunction collapse offer an appealing explanation of the possible breakdown of quantum mechanics for macroscopic systems. However, the challenge of resolving predicted collapse signatures above background noise has precluded conclusive tests. Here, we propose to overcome this challenge using a superconducting qubit to precisely readout the collapse-induced heating of a mechanical resonator. We show that the ability to strongly couple the qubit to the resonator can…

An Introduction to the Transmon Qubit for Electromagnetic Engineers

One of the most popular approaches being pursued to achieve a quantum advantage with practical hardware are superconducting circuit devices. Although significant progress has been made over the

Electro-Mechanical Tuning of High-Q Bulk Acoustic Phonon Modes at Cryogenic Temperatures

By applying a DC bias voltage, we demonstrate broad frequency tuning of high-Q phonon modes in a quartz bulk acoustic wave cavity at 4K, whilst also observing similar tuning when cooled to
