Nonreciprocity in microwave optomechanical circuits
N. R. Bernier, L. D. Tóth, A. K. Feofanov +1
Nonreciprocal devices such as isolators and circulators are necessary to protect sensitive apparatus from unwanted noise. Recently, a variety of alternatives were proposed to repla…
Quantum-limited directional amplifiers with optomechanics
Daniel Malz, László D. Tóth, Nathan R. Bernier +3
Directional amplifiers are an important resource in quantum information processing, as they protect sensitive quantum systems from excess noise. Here, we propose an implementation…
Nonreciprocal reconfigurable microwave optomechanical circuit
N. R. Bernier, L. D. Tóth, A. Koottandavida +5
Devices that achieve nonreciprocal microwave transmission are ubiquitous in radar and radio-frequency communication systems, and commonly rely on magnetically biased ferrite materi…
A dissipative quantum reservoir for microwave light using a mechanical oscillator
L. D. Tóth, N. R. Bernier, A. Nunnenkamp +2
Isolation of a system from its environment is often desirable, from precision measurements to control of individual quantum systems; however, dissipation can also be a useful resou…
On-chip microwave-to-optical quantum coherent converter based on a superconducting resonator coupled to an electro-optic microresonator
Clément Javerzac-Galy, Kirill Plekhanov, Nathan Bernier +3
We propose a device architecture capable of direct quantum electro-optical conversion of microwave to optical photons. The hybrid system consists of a planar superconducting microw…
Paradigms for Quantum Feedback Control
L. D. Tóth
In this review paper, we survey the main concepts and some of the recent developments in quantum feedback control. For consistency and clarity, essential ideas and notations in the…
