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…
Level attraction in a microwave optomechanical circuit
N. R. Bernier, L. D. Tóth, A. K. Feofanov +1
Level repulsion - the opening of a gap between two degenerate modes due to coupling - is ubiquitous anywhere from solid state theory to quantum chemistry. In contrast, if one mode…
A maser based on dynamical backaction on microwave light
L. D. Tóth, N. R. Bernier, A. K. Feofanov +1
The work of Braginsky introduced radiation pressure dynamical backaction, in which a mechanical oscillator that is parametrically coupled to an electromagnetic mode can experience…
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…
