Abstract
In the Quantum Optics Group at Caltech, the strong coupling of an atom to the field of a high finesse optical cavity is being exploited to realize a menagerie of new physical effects. For example, we have reported the first demonstration of conditional dynamics at the single-photon level suitable for the implementation of quantum logic [l].Since in our scheme “flying qubits” would be single-photon pulses with the internal state specified by s± polarization, we are pursuing a theoretical investigation of the time-dependent, nonlinear interaction of single-photon wavepackets with the atom-cavity system, including the generation of entanglement and the violation of Bell inequalities. In more practical terms, we are conducting experiments which excite the atom-cavity system with correlated pairs of photons (i.e., squeezed light) to explore its behavior for manifestly quantum or nonclassical inputs (a diet of “quantum food”).
