Quantum trajectory theory of superradiant emission from randomly distributed atomic samples

Ryan Nowak, James Clemens

We consider the directed superradiant emission from a collection of N two-state atoms with arbitrary spatial locations within the framework of quantum trajectory theory and without a single-mode assumption. The formalism is developed around an unravelling of the master equation in terms of source mode quantum jumps. A modified boson approximation is made to treat the many-atom case, where it is found that strong directional superradiance occurs for a few thousand atoms, even with randomized atomic positions.

Stochastic initiation of superradiance in a cavity: An approximation scheme within quantum trajectory theory

James Clemens, H. J. Carmichael

We investigate the stochastic initiation of superradiant emission from a collection of excited two-state atoms coupled through a low-Q cavity mode. Noncollective emission into other modes of the electromagnetic field is included, allowing us to describe the transition from predominantly noncollective to collective behavior as the number of atoms is increased. We examine the dependence of the photon statistics on the number of atoms and the ratio of collective to noncollective decay rates. Numerical results for a few to ${10}^{6}$ atoms are obtained using an approximation scheme developed within the framework of quantum trajectory theory. Results are compared with those for a pure collective emission process and an earlier treatment of noncollective effects.

Fidelity of a Conditional Quantum Teleportation Protocol Based on Imperfect Detection of Collective Spontaneous Emission

Richard Wagner Jr., James Clemens

We employ quantum trajectory theory to model temporally resolved photodetection of collective emission from a pair of atoms to investigate the performance of a conditional quantum teleportation protocol. We include effects of imperfect photodetection.
