Single Photon Quantum Control Via High-χ(3) Media

Abstract

We discuss the generation of very large χ (3) nonlinearities via electromagnetically-induced transparency, and the applications of these to quantum control with single photons. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

Photoionization and Interatomic Coulombic Decay

Kirsten Schnorr

The type of process that may be induced in an atom by the interaction with a single photon is strongly dependent on the photon energy. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

Researchers are exploring ways to use electromagnetically induced transparency on individual light quanta, laying the groundwork for intriguing applications in quantum information science that use photons as information carriers, and atomic ensembles as memory and processing nodes.

Two-Photon Interactions for Use in Quantum Computing

J. D. Franson, T. B. Pittman

Nonlinear interactions between two photons would have many potential applications, including the implementation of quantum logic gates for use in quantum computing. We are investigating a new mechanism for nonlinear optics at the two-photon level that is based on the exchange of photons by pairs of atoms in a medium, such as an atomic vapor. The effect can be understood as being due to a factor of two increase in the probability of having two excited atoms in the medium compared to the case in which the two photons propagate in two separate media. These effects are expected to be sufficiently large that cavities and traps should not be required, which may eventually allow the construction of large numbers of simple quantum logic gates. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

Quantum control of light using electromagnetically induced transparency

Axel André, Matthew D. Eisaman, Ronald Lee Walsworth +2 more

We present an overview of recent theoretical and experimental work on the control of the propagation and quantum properties of light using electromagnetically induced transparency in atomic ensembles. Specifically, we discuss techniques for the generation and storage of few-photon quantum-mechanical states of light as well as novel approaches to manipulate weak pulses of light via enhanced nonlinear optical processes.

Quantum Controllable Optical Selectivity of Single-Photon Excitation in a Dense Medium

Han Xu, Heping Zeng

Selective multiphoton excitations can be achieved by tailoring the driving pulses to manipulate the outcome of the light-matter interaction. While single-photon transitions of single atoms driven by ultrashort pulses, dependent mainly on the resonant frequency component, and thus possesses no optical selectivity no matter how the excitation pulse shapes [1]. Interestingly, when an ultrashort pulse interacts with an optically dense medium, quantum controllable optical selectivity can be achieved in a single-photon process.

Sub-Cycle Pulses and Field Solitons: Near- and Sub-Femtosecond Em-Bubbles

A. E. Kaplan, S. F. Straub, P. L. Shkolnikov

We demonstrate the feasibility of strong (up to atomic fields) and super-short (few- or even sub-femtosecond) sub-cycle (non-oscillating) electromagnetic solitons — EM bubbles (EMBs) in a gas of two-level atoms, as well as EMBs and pre-ionization shock waves in classically nonlinear atoms. We show that EMBs can be generated by existing sources of radiation, including sub-picosecond half-cycle pulses and very short laser pulses. We investigate how EMB characteristics are controlled by those of originating pulses. Our most recent results are focused on the related transient phenomena, including EMB formation length, multi-bubble generation and shock-like waves. We also develop the theory of the diffraction-induced transformation of sub-cycle pulses in linear media. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
