Establishing a reliable method to form scalable neutral-atom platforms is an essential cornerstone for quantum computation, quantum simulation and quantum many-body physics. Here we demonstrate a real-time transport of single atoms using holographic ...

M. Serina, Christoph Kloeffel, D. Loss·Jan 14, 2016

We analyze and give estimates for the long-distance coupling via floating metallic gates between different types of spin qubits in quantum dots made of different commonly used materials. In particular, we consider the hybrid, the singlet-triplet, and...

How to single out the right atoms For a quantum computer to be useful, its qubits have to be able to change their state in response to external stimuli. But when a large number of qubits are packed in a three-dimensional (3D) structure to optimize th...

Mallikarjun Karra, Ketan Sharma, B. Friedrich +2 more·Jan 11, 2016

Arrays of trapped ultracold molecules represent a promising platform for implementing a universal quantum computer. DeMille [Phys. Rev. Lett. 88, 067901 (2002)] has detailed a prototype design based on Stark states of polar (1)Σ molecules as qubits. ...

Blind quantum computing allows for secure cloud networks of quasi-classical clients and a fully fledged quantum server. Recently, a new protocol has been proposed, which requires a client to perform only measurements. We demonstrate a proof-of-princi...

Nicolas Gheeraert, S. Bera, S. Florens·Jan 7, 2016

Josephson circuits provide a realistic physical setup where the light–matter fine structure constant can become of order one, allowing to reach a regime dominated by non-perturbative effects beyond standard quantum optics. Simple processes, such as s...

G. Dvali, M. Panchenko·Jan 6, 2016

Analyzing some well established facts, we give a model‐independent parameterization of black hole quantum computing in terms of a set of macro and micro quantities and their relations. These include the relations between the extraordinarily‐small ene...

K. Chiu, Yang Xu·Jan 5, 2016

Two-dimensional (2D) materials for their versatile band structures and strictly 2D nature have attracted considerable attention over the past decade. Graphene is a robust material for spintronics owing to its weak spin-orbit and hyperfine interaction...

R. Taylor, C. Bentley, J. S. Pedernales +4 more·Jan 4, 2016

Large-scale digital quantum simulations require thousands of fundamental entangling gates to construct the simulated dynamics. Despite success in a variety of small-scale simulations, quantum information processing platforms have hitherto failed to d...

A. Mohanty, Mian Zhang, A. Dutt +3 more·Jan 1, 2016

Integrated quantum optics has the potential to markedly reduce the footprint and resource requirements of quantum information processing systems, but its practical implementation demands broader utilization of the available degrees of freedom within ...

Francesco Ticozzi, Luca Mazzarella, Alain Sarlette·Mar 14, 2014

In this paper we propose a continuous-time, dissipative Markov dynamics that asymptotically drives a network of n-dimensional quantum systems to the set of states that are invariant under the action of the subsystem permutation group. The Lindblad-ty...

Cesar E. Pachon, Leonardo A. Pachon·Jul 16, 2013

Non-locality is one of the hallmarks of quantum mechanics and is responsible for paradigmatic features such as entanglement and the Aharonov-Bohm effect. Non-locality comes in two flavours: a \emph{kinematic} non-locality -- arising from the structur...

Thierry Jecko·Mar 23, 2013

Motivated by a paper by B.T. Sutcliffe and R.G. Woolley, we present the main ideas used by mathematicians to show the accuracy of the Born-Oppenheimer approximation for molecules. Based on mathematical works on this approximation for molecular bound ...

Vladan Pankovic·Jun 11, 2010

In this work we accurately consider quantum dynamical interaction (or entanglement) between single photon and usual photographic plate as photon coordinate detector in well-known experiments of single photon interference at beam splitter (and analogo...

Andrea Mari·Jan 12, 2009

In this thesis we study continuous variable systems, focusing on optomechanical devices where a laser field interacts with a macroscopic mechanical oscillator through radiation pressure. We consider the optimization problem of quantum teleportation b...

Duje Bonacci·Sep 16, 2003

We introduce the \emph{Rabi profile}, the \emph{Rabi spectrum} and the \emph{Rabi leak} as triad of mathematically rigorous but conceptually transparent quantum-control tools that provide a framework for assessing the feasibility and selectivity of c...

H. Barnum, E. Knill·Apr 23, 2000

We consider the problem of reversing quantum dynamics, with the goal of preserving an initial state's quantum entanglement or classical correlation with a reference system. We exhibit an approximate reversal operation, adapted to the initial density ...
