Microwave measurement beyond the quantum limit with a nonreciprocal amplifier
F. Lecocq, L. Ranzani, G. A. Peterson +6
The measurement of a quantum system is often performed by encoding its state in a single observable of a light field. The measurement efficiency of this observable can be reduced b…

Emerging unitary evolutions in dissipatively coupled systems
C. Arenz, A. Metelmann
Having a broad range of methods available for implementing unitary operations is crucial for quantum information tasks. We study a dissipative process commonly used to describe dis…

Exceptional points-based optical amplifiers
Q. Zhong, S. K. Ozdemir, A. Eisfeld +2
The finite gain-bandwidth product is a fundamental figure of merit that restricts the operation of standard optical amplifiers. In microcavity setups, this becomes a serious proble…
