Crystallization of strongly interacting photons in a nonlinear optical fiber
D. E. Chang, V. Gritsev, G. Morigi +3
Understanding strongly correlated quantum systems is a central problem in many areas of physics. The collective behavior of interacting particles gives rise to diverse fundamental…
Anyonic interferometry and protected memories in atomic spin lattices
Liang Jiang, Gavin K. Brennen, Alexey V. Gorshkov +5
Strongly correlated quantum systems can exhibit exotic behavior called topological order which is characterized by non-local correlations that depend on the system topology. Such s…
Optimal approach to quantum communication using dynamic programming
Liang Jiang, Jacob M. Taylor, Navin Khaneja +1
Reliable preparation of entanglement between distant systems is an outstanding problem in quantum information science and quantum communication. In practice, this has to be accompl…
Photon storage in Lambda-type optically dense atomic media. IV. Optimal control using gradient ascent
Alexey V. Gorshkov, Tommaso Calarco, Mikhail D. Lukin +1
We use the numerical gradient ascent method from optimal control theory to extend efficient photon storage in Lambda-type media to previously inaccessible regimes and to provide si…
Distributed Quantum Computation Based-on Small Quantum Registers
Liang Jiang, Jacob M. Taylor, Anders S. Sørensen +1
We describe and analyze an efficient register-based hybrid quantum computation scheme. Our scheme is based on probabilistic, heralded optical connection among local five-qubit quan…
Quantum Spin Dynamics of Mode-Squeezed Luttinger Liquids in Two-Component Atomic Gases
Artur Widera, Stefan Trotzky, Patrick Cheinet +6
We report on the observation of the phase dynamics of interacting one-dimensional ultracold bosonic gases with two internal degrees of freedom. By controlling the non-linear atomic…
