Robustness of non-adiabatic holonomic gates
Markus Johansson, Erik Sjöqvist, L. Mauritz Andersson +4
The robustness to different sources of error of the scheme for non-adiabatic holonomic gates proposed in [New J. Phys. {\bf 14}, 103035 (2012)] is investigated. Open system effects…
Non-adiabatic holonomic quantum computation
Erik Sjöqvist, D. M. Tong, L. Mauritz Andersson +3
We develop a non-adiabatic generalization of holonomic quantum computation in which high-speed universal quantum gates can be realized by using non-Abelian geometric phases. We sho…
An integrated atom detector: single atoms and photon statistics
Dennis Heine, Marco Wilzbach, Thomas Raub +2
We demonstrate a robust fiber-optics-based fluorescence detector, fully integrated on an atom chip, which detects single atoms propagating in a guide with 66% efficiency. We charac…
An experimental demonstration of single photon nonlocality
Björn Hessmo, Pavel Usachev, Hoshang Heydari +1
In this letter we experimentally implement a single photon Bell test based on the ideas of S. Tan et al. [Phys. Rev. Lett., vol. 66, 252 (1991)] and L. Hardy [Phys. Rev. Lett.,vol.…
Quantum limits on phase-shift detection using multimode interferometers
Jonas Soderholm, Gunnar Bjork, Bjorn Hessmo +1
Fundamental phase-shift detection properties of optical multimode interferometers are analyzed. Limits on perfectly distinguishable phase shifts are derived for general quantum sta…
Multi Mode Interferometer for Guided Matter Waves
Erika Andersson, Tommaso Calarco, Ron Folman +3
We describe the fundamental features of an interferometer for guided matter waves based on Y-beam splitters and show that, in a quasi two-dimensional regime, such a device exhibits…
