Parametric Couplings in Engineered Quantum Systems
A. Metelmann
Parametric couplings in engineered quantum systems are a powerful tool to control, manipulate and enhance interactions in a variety of platforms. It allows us to bring systems of d…
High-Purity Entanglement of Hot Propagating Modes Using Nonreciprocity
Lindsay Orr, Saeed A. Khan, Nils Buchholz +2
Distributed quantum information processing and communication protocols demand the ability to generate entanglement among propagating modes. However, thermal fluctuations can severe…
Non-universality of quantum noise in optical amplifiers operating at exceptional points
L. Simonson, S. K. Ozdemir, A. Eisfeld +2
The concept of exceptional points-based optical amplifiers (EPOAs) has been recently proposed as a new paradigm for miniaturizing optical amplifiers while simultaneously enhancing…
Quantum-limited amplification without instability
A. Metelmann, O. Lanes, T-Z. Chien +4
Quantum parametric amplifiers typically generate by operating in proximity to a point of dynamical instability. We consider an alternate general strategy where quantum-limited, lar…
Embedding of Time-Delayed Quantum Feedback in a Nonreciprocal Array
Xin H. H. Zhang, S. H. L. Klapp, A. Metelmann
Time-delayed quantum feedback is a fast and efficient method to control and stabilize few and many-body quantum systems. However, a proper understanding of such systems stays opaqu…
Kerr enhanced backaction cooling in magnetomechanics
D. Zoepfl, M. L. Juan, N. Diaz-Naufal +5
Optomechanics is a prime example of light matter interaction, where photons directly couple to phonons, allowing to precisely control and measure the state of a mechanical object.…
