Strong-coupling effects in dissipatively coupled optomechanical systems
Talitha Weiss, Christoph Bruder, Andreas Nunnenkamp
In this paper we study cavity optomechanical systems in which the position of a mechanical oscillator modulates both the resonance frequency (dispersive coupling) and the linewidth…
Nonsymmetrized Correlations in Quantum Noninvasive Measurements
Adam Bednorz, Christoph Bruder, Bertrand Reulet +1
A long-standing problem in quantum mesoscopic physics is which operator order corresponds to noise expressions like <I(-ω)I(ω)>, where I(ω) is the measured current at frequency ω.…
Majorana qubit rotations in microwave cavities
Thomas L. Schmidt, Andreas Nunnenkamp, Christoph Bruder
Majorana bound states have been proposed as building blocks for qubits on which certain operations can be performed in a topologically protected way using braiding. However, the se…
Mean-Field Analysis of Spinor Bosons in Optical Superlattices
Andreas Wagner, Andreas Nunnenkamp, Christoph Bruder
We study the ground-state phase diagram of spinless and spin-1 bosons in optical superlattices using a Bose-Hubbard Hamiltonian that includes spin-dependent interactions. We decoup…
Preserving universal resources for one-way quantum computing
Tetsufumi Tanamoto, Daniel Becker, Vladimir M. Stojanović +1
The common spin Hamiltonians such as the Ising, XY, or Heisenberg model do not have ground states that are the graph states needed in measurement-based quantum computation. Various…
