Quantum Cryptography with Entangled Photons

Thomas Jennewein, Christoph Simon, Gregor Weihs +2

By realizing a quantum cryptography system based on polarization entangled photon pairs we establish highly secure keys, because a single photon source is approximated and the inhe…

Entanglement of Atomic Ensembles by Trapping Correlated Photon States

M. D. Lukin, S. F. Yelin, M. Fleischhauer

We describe a general technique that allows for an ideal transfer of quantum correlations between light fields and metastable states of matter. The technique is based on trapping q…

How to Trap Photons? Storing Single-Photon Quantum States in Collective Atomic Excitations

M. Fleischhauer, S. F. Yelin, M. D. Lukin

We show that it is possible to ``store'' quantum states of single-photon fields by mapping them onto {\it collective} meta-stable states of an optically dense, coherently driven me…

High-Fidelity Teleportation of Independent Qubits

Dik Bouwmeester, Jian-Wei Pan, Harald Weinfurter +1

Quantum teleportation is one of the essential primitives of quantum communication. We suggest that any quantum teleportation scheme can be characterized by its efficiency, i.e. how…

On mechanisms that enforce complementarity

Berthold-Georg Englert, Marlan O. Scully, Herbert Walther

In a recent publication Luis and Sanchez-Soto arrive at the conclusion that complementarity is universally enforced by random classical phase kicks. We disagree. One could just as…

Threshold and linewidth of a mirrorless parametric oscillator

M. Fleischhauer, M. D. Lukin, A. B. Matsko +1

We analyze the above-threshold behavior of a mirrorless parametric oscillator based on resonantly enhanced four wave mixing in a coherently driven dense atomic vapor. It is shown t…

Quantum computing with neutral atoms

H. -J. Briegel, T. Calarco, D. Jaksch +2

We develop a method to entangle neutral atoms using cold controlled collisions. We analyze this method in two particular set-ups: optical lattices and magnetic micro-traps. Both of…

Spontaneous emission and level shifts in absorbing disordered dielectrics and dense atomic gases: A Green's function approach

Michael Fleischhauer

Spontaneous emission and Lamb shift of atoms in absorbing dielectrics are discussed. A Green's-function approach is used based on the multipolar interaction Hamiltonian of a collec…
