Nonlocal modulation and dispersion
Abstract/Contents
- Abstract
- Quantum entanglement has been the subject of a growing field in quantum optics that aims to study the physical properties of entangled systems and find new applications for their use. Entangled photons have been proposed as a means to achieve long distance quantum communications and cryptography, perform computational tasks beyond the capabilities of classical computers, image beyond the classical limit, and provide measurement sensitivities unobtainable with analogous classical light sources. At the heart of these applications is the fact that entangled photons behave strikingly different from classical light or even pairs of independent single photons. This thesis reviews an interference effect known as nonlocal cancellation of dispersion and proposes and demonstrates a new, analogous effect which we term as nonlocal modulation. These techniques allow one to undo the effect of one dispersive medium or phase modulator with a similar system at a distant point in space, as observed by correlations between entangled photons. We explore the use of nonlocal dispersion compensation, combined with chirped quasi-phase-matched nonlinear crystals, to generate ultrashort entangled photons with high generation rates. To aid in the measurement of ultrashort entangled photons, we propose and demonstrate a resonance technique to increase the sensitivity of ultrafast sum-frequency-generation correlators. Principal accomplishments of this work include: the first observation of nonlocal modulation, the first observation of the radar-like "chirp and compress" technique with entangled photons, and the first experimental demonstration of resonant sum frequency generation using broadband biphotons.
