Measurement and control of quantum acoustic systems
Abstract
Recent advances in superconducting circuit technology have enabled the measurement and control of electromechanical systems in the quantum regime. This includes the measurement of mechanical oscillators near the quantum limit, the entanglement of mechanical oscillators, and the mechanically-mediated amplification and frequency conversion of microwave signals near the quantum limit.The objectives of this Project are to:1. Design and analyze an electromechanical system to facilitate a Bell test of quantum mechanics in a qualitatively new regime; that is, with massive mechanical objects.2. Design and analyze an electromechanical travelling-wave amplifier to facilitate broadband, high-power, near-quantum-limited amplification.This Project will lay the platform for the future experimental realization of a new generation of quantum electromechanical devices. Sub-project 1 potentially has profound implications for quantum mechanics, and any theory that might potentially supersede quantum mechanics. Sub-project 2 will be crucial to the development of multiplexed read-out for superconducting quantum computers. More broadly, ultralow- noise microwave amplifiers are crucial in a variety of applications, including radio astronomy, deep space communications, space surveillance, and satellite communications.
