Braiding of non-Abelian anyons using pairwise interactions
M. Burrello, B. van Heck, A. R. Akhmerov
The common approach to topological quantum computation is to implement quantum gates by adiabatically moving non-Abelian anyons around each other. Here we present an alternative pe…
Quantum collapses and revivals of a matter wave in the dynamics of symmetry breaking
Frank Kirtschig, Jorrit Rijnbeek, Jeroen van den Brink +1
Using the remarkable mathematical construct of Eugene Wigner to visualize quantum trajectories in phase space, quantum processes can be described in terms of a quasi-probability di…
Macroscopic superpositions via nested interferometry: finite temperature and decoherence considerations
Brian Pepper, Evan Jeffrey, Roohollah Ghobadi +2
Recently there has been much interest in optomechanical devices for the production of macroscopic quantum states. Here we focus on a proposed scheme for achieving macroscopic super…
Tomography and state reconstruction with superconducting single-photon detectors
Jelmer J. Renema, Giulia Frucci, Michiel J. A. de Dood +3
We perform quantum state reconstruction of coherent and thermal states with a detector which has an enhanced multiphoton response. The detector is based on superconducting nanowire…
Determining the dimensionality of bipartite orbital-angular-momentum entanglement using multi-sector phase masks
D. Giovannini, F. M. Miatto, J. Romero +3
The Shannon dimensionality of orbital angular momentum (OAM) entanglement produced in spontaneous parametric down-conversion can be probed by using multi-sector phase analysers. We…
Full-field quantum correlations of spatially entangled photons
V. D. Salakhutdinov, E. R. Eliel, W. Löffler
Spatially entangled twin photons allow the study of high-dimensional entanglement, and the Laguerre-Gauss modes are the most commonly used basis to discretize the single photon mod…
