Noiseless quantum measurement and squeezing of microwave fields utilizing mechanical vibrations
C. F. Ockeloen-Korppi, E. Damskägg, J. -M. Pirkkalainen +3
A process which strongly amplifies both quadrature amplitudes of an oscillatory signal necessarily adds noise. Alternatively, if the information in one quadrature is lost in phase-…
Dynamically creating tripartite resonance and dark modes in a multimode optomechanical system
E. Damskägg, J. -M. Pirkkalainen, M. A. Sillanpää
We study a multimode optomechanical system where two mechanical oscillators are coupled to an electromagnetic cavity. Previously it has been shown that if the mechanical resonances…
Quantum back-action evading measurement of collective mechanical modes
C. F. Ockeloen-Korppi, E. Damskägg, J. -M. Pirkkalainen +3
The standard quantum limit constrains the precision of an oscillator position measurement. It arises from a balance between the imprecision and the quantum back-action of the measu…
Low-noise amplification and frequency conversion with a multiport microwave optomechanical device
C. F. Ockeloen-Korppi, E. Damskägg, J. -M. Pirkkalainen +3
High-gain amplifiers of electromagnetic signals operating near the quantum limit are crucial for quantum information systems and ultrasensitive quantum measurements. However, the e…
