CM-AMO Seminar | Entanglement and Indistinguishability in Photons from Quantum Dots

Tuesday, April 13, 2010
4:00 AM
335 West Hall

Speaker: Glenn Solomon (NIST, Gettysburg)

Semiconductor quantum dots (QDs) of InAs in GaAs are bright emitters of discrete photons. They can be used in a variety of fundamental quantum optics experiments and will likely contribute to emerging applications in quantum information. Professor Solomon will discuss recent experiments in manipulating individual QDs states to tailor the character of the emitted photons. The use of optical cavities and tuning fields can control the degree of entanglement and indistinguishability of these photons. These experiments demonstrate that while photons emitted from solid-state structures are often adversely influences by their environment, this can be rectify.
