Ultracold atoms in radio-frequency-dressed potentials beyond the rotating wave approximation
S. Hofferberth, B. Fischer, T. Schumm +2
We study dressed Bose-Einstein condensates in an atom chip radio-frequency trap. We show that in this system sufficiently strong dressing can be achieved to cause the widely used r…
Quantum randomness and value indefiniteness
Cristian S. Calude, Karl Svozil
As computability implies value definiteness, certain sequences of quantum outcomes cannot be computable.
Experimental Quantum Teleportation of a Two-Qubit Composite System
Qiang Zhang, Alexander Goebel, Claudia Wagenknecht +6
Quantum teleportation, a way to transfer the state of a quantum system from one location to another, is central to quantum communication and plays an important role in a number of…
Transient localization in the kicked Rydberg atom
E. Persson, S. Fürthauer, S. Wimberger +1
We investigate the long-time limit of quantum localization of the kicked Rydberg atom. The kicked Rydberg atom is shown to possess in addition to the quantum localization time $τ_L…
Contexts in quantum, classical and partition logic
Karl Svozil
Contexts are maximal collections of co-measurable observables "bundled together" to form a "quasi-classical mini-universe." Different notions of contexts are discussed for classica…
Robust creation of entanglement between remote memory qubits
Bo Zhao, Zeng-Bing Chen, Yu-Ao Chen +2
In this Letter we propose a robust quantum repeater architecture building on the original DLCZ protocol [L.M. Duan \textit{et al.}, Nature \textbf{414}, 413 (2001)]. The architectu…
