A cryogenic electro-optic interconnect for superconducting devices
Tobias Kippenberg, Amir Youssefi, Anton Lukashchuk, Nathan Rafaël Bernier, Liu Qiu, Itay Shomroni
A major challenge to the scalability of cryogenic computing platforms is the heat load associated with the growing number of electrical cable connections between the superconducting circuitry and the room-temperature environment. Compared with electrical c ...
2021Optomechanical generation of a mechanical catlike state by phonon subtraction
Tobias Kippenberg, Liu Qiu, Itay Shomroni
We propose a scheme to prepare a macroscopic mechanical oscillator in a catlike state, close to a coherent state superposition. The mechanical oscillator, coupled by radiation-pressure interaction to a field in an optical cavity, is first prepared close to ...
AMER PHYSICAL SOC2020Laser Cooling of a Nanomechanical Oscillator to Its Zero-Point Energy
Tobias Kippenberg, Liu Qiu, Itay Shomroni
Optomechanical systems in the well-resolved-sideband regime are ideal for studying a myriad of quantum phenomena with mechanical systems, including backaction-evading measurements, mechanical squeezing, and nonclassical states generation. For these experim ...
AMER PHYSICAL SOC2020Optical backaction-evading measurement of a mechanical oscillator
Tobias Kippenberg, Liu Qiu, Itay Shomroni
Quantum mechanics imposes a limit on the precision of a continuous position measurement of a harmonic oscillator, due to backaction arising from quantum fluctuations in the measurement field. This standard quantum limit can be surpassed by monitoring only ...
Springer2019Floquet dynamics in the quantum measurement of mechanical motion
Tobias Kippenberg, Nicolas Piro Mastracchio, Liu Qiu, Itay Shomroni, Marie Adrienne Ioannou
The radiation-pressure interaction between one or more laser fields and a mechanical oscillator gives rise to a wide range of phenomena: From sideband cooling and backaction-evading measurements to ponderomotive and mechanical squeezing to entanglement and ...
AMER PHYSICAL SOC2019Two-Tone Optomechanical Instability and Its Fundamental Implications for Backaction-Evading Measurements
Tobias Kippenberg, Amir Youssefi, Liu Qiu, Itay Shomroni
While quantum mechanics imposes a fundamental limit on the precision of interferometric measurementsof mechanical motion due to measurement backaction, the nonlinear nature of the coupling also leads toparametric instabilities that place practical limits o ...
2019Quantum Motional Sideband Asymmetry in the Presence of Kerr-type Nonlinearities
Tobias Kippenberg, Liu Qiu, Itay Shomroni, Marie Adrienne Ioannou
Sideband asymmetry between the Stokes and anti-Stokes scattering is a signature of the mechanical oscillators in the quantum regime. It has been demonstrated in several optomechanical systems, as a self-calibrated thermometry method. We present motional si ...
IEEE2018Backaction-evading measurement of mechanical motion in the optical domain
Tobias Kippenberg, Liu Qiu, Itay Shomroni
When measuring the position of a mechanical oscillator, quantum mechanics imposes a strict limit on the attainable precision: Any reduction of imprecision leads to increased quantum backaction of the measuring probe on the oscillator. This quantum limit ca ...
