Indistinguishability of quantum states and rotation counting
Dmitri V. Averin, Christoph Bruder
We propose a quantum system in which the winding number of rotations of a particle around a ring can be monitored and emerges as a physical observable. We explicitly analyze the si…
Noninvasive Quantum Measurement of Arbitrary Operator Order by Engineered Non-Markovian Detectors
Johannes Bülte, Adam Bednorz, Christoph Bruder +1
The development of solid-state quantum technologies requires the understanding of quantum measurements in interacting, non-isolated quantum systems. In general, a permanent couplin…
Quantum Synchronization Blockade: Energy Quantization hinders Synchronization of Identical Oscillators
Niels Lörch, Simon E. Nigg, Andreas Nunnenkamp +2
Classically, the tendency towards spontaneous synchronization is strongest if the natural frequencies of the self-oscillators are as close as possible. We show that this wisdom fai…
Synchronization of an optomechanical system to an external drive
Ehud Amitai, Niels Lörch, Andreas Nunnenkamp +2
Optomechanical systems driven by an effective blue detuned laser can exhibit self-sustained oscillations of the mechanical oscillator. These self-oscillations are a prerequisite fo…
