Energy-level-attraction and heating-resistant-cooling of mechanical resonators with exceptional points
Cheng Jiang, Yu-Long Liu, Mika A. Sillanpää
We study the energy-level evolution and ground-state cooling of mechanical resonators under a synthetic phononic gauge field. The tunable gauge phase is mediated by the phase diffe…
Quantum-mechanics free subsystem with mechanical oscillators
Laure Mercier de Lépinay, Caspar F. Ockeloen-Korppi, Matthew J. Woolley +1
Quantum mechanics sets a limit for the precision of continuous measurement of the position of an oscillator. Here we show how it is possible to measure an oscillator without quantu…
Sideband control of a multimode quantum bulk acoustic system
Mikael Kervinen, Alpo Välimaa, Jhon E. Ramírez-Muñoz +1
Multimode bulk acoustic systems show promise for use in superconducting quantum computation. They can serve as a medium term memory storage, with exceptional coherence times demons…
