Quantum Scanning Microscope for Cold Atoms
Dayou Yang, Denis V. Vasilyev, Catherine Laflamme +2
We present a detailed theoretical description of an atomic scanning microscope in a cavity QED setup proposed in Phys. Rev. Lett. 120, 133601 (2018). The microscope continuously ob…
Theory of a Quantum Scanning Microscope for Cold Atoms
Dayou Yang, Catherine Laflamme, Denis Vasilyev +2
We propose and analyze a scanning microscope to monitor `live' the quantum dynamics of cold atoms in a Cavity QED setup. The microscope measures the atomic density with subwaveleng…
Continuous Measurement of an Atomic Current
C. Laflamme, D. Yang, P. Zoller
We are interested in dynamics of quantum many-body systems under continuous observation, and its physical realizations involving cold atoms in lattices. In the present work we focu…
Non-equilibrium Josephson Effect in Atomic Kitaev Wires
C. Laflamme, J. C. Budich, P. Zoller +1
We theoretically study a Kitaev wire interrupted by an extra site which gives rise to super exchange coupling between two Majorana bound states. We show that this system hosts a tu…
Proposal for the Quantum Simulation of the CP(2) Model on Optical Lattices
Catherine Laflamme, Wynne Evans, Marcello Dalmonte +5
The 2d CP(N-1) models share a number of features with QCD, like asymptotic freedom, a dynamically generated mass gap and topological sectors. They have been formulated and analysed…
CP(N-1) Quantum Field Theories with Alkaline-Earth Atoms in Optical Lattices
C. Laflamme, W. Evans, M. Dalmonte +5
We propose a cold atom implementation to attain the continuum limit of (1+1)-d CP(N-1) quantum field theories. These theories share important features with (3+1)-d QCD, such as asy…
Synthetic Helical Liquids with Ultracold Atoms in Optical Lattices
J. C. Budich, C. Laflamme, F. Tschirsich +2
We discuss a platform for the synthetic realization of key physical properties of helical Tomonaga Luttinger liquids (HTLLs) with ultracold fermionic atoms in one-dimensional optic…
Hybrid Topological Quantum Computation with Majorana Fermions: A Cold Atom Setup
C. Laflamme, M. A. Baranov, P. Zoller +1
In this paper we present a hybrid scheme for topological quantum computation in a system of cold atoms trapped in an atomic lattice. A topological qubit subspace is defined using M…
Weak Qubit Measurement with a Nonlinear Cavity: Beyond Perturbation Theory
Catherine Laflamme, Aashish A. Clerk
We analyze the use of a driven nonlinear cavity to make a weak continuous measurement of a dispersively-coupled qubit. We calculate the backaction dephasing rate and measurement ra…
Quantum limited amplification with a nonlinear cavity detector
Catherine Laflamme, Aashish A. Clerk
We consider the quantum measurement properties of a driven cavity with a Kerr-type nonlinearity which is used to amplify a dispersively coupled input signal. Focusing on an operati…
