Nested Quantum Walks with Quantum Data Structures
Stacey Jeffery, Robin Kothari, Frederic Magniez
We develop a new framework that extends the quantum walk framework of Magniez, Nayak, Roland, and Santha, by utilizing the idea of quantum data structures to construct an efficient…
Entanglement-enabled delayed choice experiment
F. Kaiser, T. Coudreau, P. Milman +2
Complementarity, that is the ability of a quantum object to behave either as a particle or as a wave, is one of the most intriguing features of quantum mechanics. An exemplary Geda…
Ultra-stable long distance optical frequency distribution using the Internet fiber network
Olivier Lopez, Adil Haboucha, Bruno Chanteau +3
We report an optical link of 540 km for ultrastable frequency distribution over the Internet fiber network. The stable frequency optical signal is processed enabling uninterrupted…
Degrees of entanglement for multipartite systems
A. I. Solomon, C. -L. Ho, G. H. E. Duchamp
We propose a unified mathematical scheme, based on a classical tensor isomorphism, for characterizing entanglement that works for pure states of multipartite systems of any number…
Coherent states and related quantizations for unbounded motions
V. G. Bagrov, J. -P. Gazeau, D. M. Gitman +1
We build coherent states (CS) for unbounded motions along two different procedures. In the first one we adapt the Malkin-Manko construction for quadratic Hamiltonians to the motion…
Large 2D Coulomb crystals in a radio frequency surface ion trap
B. Szymanski, R. Dubessy, B. Dubost +3
We designed and operated a surface ion trap, with an ion-substrate distance of 500\mum, realized with standard printed-circuit-board techniques. The trap has been loaded with up to…
