Shaking the entropy out of a lattice: atomic filtering by vibrational excitations
Malte C. Tichy, Klaus Mølmer, Jacob F. Sherson
We present a simple and efficient scheme to reduce atom-number fluctuations in optical lattices. The interaction-energy difference for atoms in different vibrational states is used…
Secure two-party quantum evaluation of unitaries against specious adversaries
Frédéric Dupuis, Jesper Buus Nielsen, Louis Salvail
We describe how any two-party quantum computation, specified by a unitary which simultaneously acts on the registers of both parties, can be privately implemented against a quantum…
Cavity Quantum Electrodynamics with a Rydberg blocked atomic ensemble
Christine Guerlin, Etienne Brion, Tilman Essslinger +1
We propose to implement the Jaynes-Cummings model by coupling a few-micrometer large atomic ensemble to a quantized cavity mode and classical laser fields. A two-photon transition…
Topological matter with collective encoding and Rydberg blockade
Anne E. B. Nielsen, Klaus Mølmer
We propose to use a permutation symmetric sample of multi-level atoms to simulate the properties of topologically ordered states. The Rydberg blockade interaction is used to prepar…
Quantum state engineering, purification, and number resolved photon detection with high finesse optical cavities
Anne E. B. Nielsen, Christine A. Muschik, Geza Giedke +1
We propose and analyze a multi-functional setup consisting of high finesse optical cavities, beam splitters, and phase shifters. The basic scheme projects arbitrary photonic two-mo…
A smoothing monotonic convergent optimal control algorithm for NMR pulse sequence design
Ivan I. Maximov, Niels Chr. Nielsen, Julien Salomon +1
The past decade has demonstrated increasing interests in using optimal control based methods within coherent quantum controllable systems. The versatility of such methods has been…
