Quantum-limited amplification and parametric instability in the reversed dissipation regime of cavity optomechanics
A. Nunnenkamp, V. Sudhir, A. K. Feofanov +2
Cavity optomechanical phenomena, such as cooling, amplification or optomechanically induced transparency, emerge due to a strong imbalance in the dissipation rates of the parametri…
Prospects for storage and retrieval of a quantum dot single photon in an ultracold Rb ensemble
Matthew T. Rakher, Richard J. Warburton, Philipp Treutlein
Epitaxially grown quantum dots (QDs) are promising sources of non-classical states of light such as single photons and entangled photons. However, in order for them to be used as a…
Matter-wave interference with particles selected from a molecular library with masses exceeding 10000 amu
Sandra Eibenberger, Stefan Gerlich, Markus Arndt +2
The quantum superposition principle, a key distinction between quantum physics and classical mechanics, is often perceived as a philosophical challenge to our concepts of reality,…
Topological Order and Reflection Positivity
Arthur Jaffe, Fabio L. Pedrocchi
The interplay between the two fundamental concepts of topological order and reflection positivity allows one to characterize the ground states of certain many-body Hamiltonians. We…
Decoding non-Abelian topological quantum memories
James R. Wootton, Jan Burri, Sofyan Iblisdir +1
The possibility of quantum computation using non-Abelian anyons has been considered for over a decade. However the question of how to obtain and process information about what erro…
A simple decoder for topological codes
James R. Wootton
Here we study an efficient algorithm for decoding the topological codes. It is based on a simple principle, which should allow straightforward generalization to complex decoding pr…
Controlling the Velocities and Number of Emitted Particles in the Tunneling to Open Space Dynamics
Axel U. J. Lode, Shachar Klaiman, Ofir. E. Alon +2
A scheme to control the many-boson tunneling process to open space is derived and demonstrated. The number of ejected particles and their velocities can be controlled by two parame…
Enhanced thermal stability of the toric code through coupling to a bosonic bath
Fabio L. Pedrocchi, Adrian Hutter, James R. Wootton +1
We propose and study a model of a quantum memory that features self-correcting properties and a lifetime growing arbitrarily with system size at non-zero temperature. This is achie…
Analog Superconducting Quantum Simulator for Holstein Polarons
Feng Mei, Vladimir M. Stojanovic, Irfan Siddiqi +1
We propose an analog quantum simulator for the Holstein molecular-crystal model based on a superconducting circuit QED system in the dispersive regime. By varying the driving field…
Equivalence between an optomechanical system and a Kerr medium
Samuel Aldana, Christoph Bruder, Andreas Nunnenkamp
We study the optical bistability of an optomechanical system in which the position of a mechanical oscillator modulates the cavity frequency. The steady-state mean-field equation o…
Vortex Loops and Majoranas
Stefano Chesi, Arthur Jaffe, Daniel Loss +1
We investigate the role that vortex loops play in characterizing eigenstates of interacting Majoranas. We first give some general results, and then we focus on ladder Hamiltonian e…
Novel Topological Phases and Self-Correcting Memories in Interacting Anyon Systems
James R. Wootton
Recent studies have shown that topological models with interacting anyonic quasiparticles can be used as self-correcting quantum memories. Here we study the behaviour of these mode…
Sequential quantum-enhanced measurement with an atomic ensemble
A. V. Lebedev, P. Treutlein, G. Blatter
We propose a quantum-enhanced iterative (with steps) measurement scheme based on an ensemble of two-level probes which asymptotically approaches the Heisenberg limit $δ_K \…
Quantum limit of laser cooling in dispersively- and dissipatively-coupled optomechanical systems
Talitha Weiss, Andreas Nunnenkamp
Mechanical oscillators can be cooled by coupling them to an optical or microwave cavity. Going beyond the standard quantum noise approach we find an analytic expression for the ste…
Quantum metrology with a scanning probe atom interferometer
Caspar F. Ockeloen, Roman Schmied, Max F. Riedel +1
We use a small atomic Bose-Einstein condensate as an interferometric scanning probe to map out a microwave field near a chip surface with a few micrometers resolution. Using entang…
Measuring ultrasmall time delays of light by joint weak measurements
Grégory Strübi, C. Bruder
We propose to use weak measurements away from the weak-value amplification regime to carry out precision measurements of time delays of light. Our scheme is robust to several sourc…
Cavity-Enhanced Long-Distance Coupling of an Atomic Ensemble to a Micromechanical Membrane
B. Vogell, K. Stannigel, P. Zoller +5
We discuss a hybrid quantum system where a dielectric membrane situated inside an optical cavity is coupled to a distant atomic ensemble trapped in an optical lattice. The coupling…
Dynamic Generation of Topologically Protected Self-Correcting Quantum Memory
Daniel Becker, Tetsufumi Tanamoto, Adrian Hutter +2
We propose a scheme to dynamically realize a quantum memory based on the toric code. The code is generated from qubit systems with typical two-body interactions (Ising, XY, Heisenb…
An efficient Markov chain Monte Carlo algorithm for the surface code
Adrian Hutter, James R. Wootton, Daniel Loss
Minimum-weight perfect matching (MWPM) has been been the primary classical algorithm for error correction in the surface code, since it is of low runtime complexity and achieves re…
Strategy for implementing stabilizer-based codes on solid-state qubits
Tetsufumi Tanamoto, Vladimir M. Stojanović, Christoph Bruder +1
We present a method for implementing stabilizer-based codes with encoding schemes of the operator quantum error correction paradigm, e.g., the "standard" five-qubit and CSS codes,…
