Nonlinear quantum dot optomechanics
Matthias Weiß, Daniel Wigger, Maximilian Nägele +5
Wave mixing is an archetypical phenomenon in bosonic systems. In optomechanics, the bi-directional conversion between electromagnetic waves or photons at optical frequencies and el…
Single atom energy-conversion device with a quantum load
Noah Van Horne, Dahyun Yum, Tarun Dutta +4
This work reports the functioning of a single atom energy-conversion device, operating either as a quantum engine or a refrigerator, coupled to a quantum load. The "working fluid"…
Ultrawide-range photon number calibration using a hybrid system combining nano-electromechanics and superconducting circuit quantum electrodynamics
Philip Schmidt, Daniel Schwienbacher, Matthias Pernpeintner +5
We present a hybrid system consisting of a superconducting coplanar waveguide resonator coupled to a nanomechanical string and a transmon qubit acting as nonlinear circuit element.…
Quantum probe of an on-chip broadband interferometer for quantum microwave photonics
P. Eder, T. Ramos, J. Goetz +11
Quantum microwave photonics aims at generating, routing, and manipulating propagating quantum microwave fields in the spirit of optical photonics. To this end, the strong nonlinear…
Solid-state magnetic traps and lattices
Johannes Knörzer, Martin J. A. Schuetz, Geza Giedke +4
We propose and analyze magnetic traps and lattices for electrons in semiconductors. We provide a general theoretical framework and show that thermally stable traps can be generated…
Compact 3D quantum memory
Edwar Xie, Frank Deppe, Michael Renger +8
Superconducting 3D microwave cavities offer state-of-the-art coherence times and a well controlled environment for superconducting qubits. In order to realize at the same time fast…
Generation and stabilization of Bell states via repeated projective measurements on a driven ancilla qubit
L. Magazzù, J. D. Jaramillo, P. Talkner +1
A protocol is proposed to generate Bell states in two non-directly interacting qubits by means of repeated measurements of the state of a central ancilla connected to both qubits.…
Quantum Brownian motion under generalized position measurements: A converse Zeno scenario
L. Magazzù, P. Talkner, P. Hänggi
We study the quantum Brownian motion of a harmonic oscillator undergoing a sequence of generalized position measurements. Our exact analytical results capture the interplay of the…
Parity-Engineered Light-Matter Interaction
Jan Goetz, Frank Deppe, Kirill G. Fedorov +6
The concept of parity describes the inversion symmetry of a system and is of fundamental relevance in the standard model, quantum information processing, and field theory. In quant…
Finite-time quantum entanglement in propagating squeezed microwaves
Kirill G. Fedorov, S. Pogorzalek, U. Las Heras +13
Two-mode squeezing is a fascinating example of quantum entanglement manifested in cross-correlations of incompatible observables between two subsystems. At the same time, these sub…
