Carbon Footprint of Academic Air Travel: A Case Study in Switzerland
László Dániel Tóth, Joachim Armand Simonne Ciers, Aleksandra Mandic
Relatively low travel costs and abundant opportunities for research funding in Switzerland and other developed countries allow researchers large amounts of international travel and collaborations, leading to a substantial carbon footprint. Increasing willi ...
2019Dissipation as a resource in circuit quantum electromechanics
A primary challenge in quantum science and technology is to isolate the fragile quantum states from their environment in order to prevent the irreversible leakage of energy and information which causes decoherence. In the late 1990s, however, a new paradig ...
EPFL2018Quantum-Limited Directional Amplifiers with Optomechanics
Tobias Kippenberg, Nathan Rafaël Bernier, László Dániel Tóth
Directional amplifiers are an important resource in quantum-information processing, as they protect sensitive quantum systems from excess noise. Here, we propose an implementation of phase-preserving and phase-sensitive directional amplifiers for microwave ...
2018Nonreciprocity in Microwave Optomechanical Circuits
Tobias Kippenberg, Nathan Rafaël Bernier, László Dániel Tóth
Nonreciprocal devices such as isolators and circulators are necessary to protect sensitive apparatus from unwanted noise. Recently, a variety of alternatives were proposed to replace ferrite-based commercial technologies, with the motivation to be integrat ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2018Nonreciprocal reconfigurable microwave optomechanical circuit
Tobias Kippenberg, Nathan Rafaël Bernier, László Dániel Tóth, Marie Adrienne Ioannou, Akshay Koottandavida
Nonreciprocal devices, such as isolators, are required to protect sensitive superconducting quantum circuits. Growing research has focused on integrated alternatives to the existing bulky ferrite technologies. Here we realize a nonreciprocal isolator with ...
IEEE2018A dissipative quantum reservoir for microwave light using a mechanical oscillator
Tobias Kippenberg, Nathan Rafaël Bernier, László Dániel Tóth
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 resource. Remarkably, engineered dissipation enables the preparation of quantum s ...
2017Nonreciprocal reconfigurable microwave optomechanical circuit
Tobias Kippenberg, Nathan Rafaël Bernier, László Dániel Tóth, Marie Adrienne Ioannou, Akshay Koottandavida
Devices that achieve nonreciprocal microwave transmission are ubiquitous in radar and radio-frequency communication systems, and commonly rely on magnetically biased ferrite materials. Such devices are also indispensable in the readout chains of supercondu ...
2017On-chip microwave-to-optical quantum coherent converter based on a superconducting resonator coupled to an electro-optic microresonator
Tobias Kippenberg, Clément Christian Javerzac-Galy, Nathan Rafaël Bernier, László Dániel Tóth
We propose a device architecture capable of direct quantum coherent electro-optical conversion of microwave-to-optical photons. The hybrid system consists of a planar superconducting microwave circuit coupled to an integrated whispering-gallery-mode micror ...
