Single photon measurements: Quantum Enhanced Measurements—Using a detector capable telling how many photons were received, we explored the potential for enhanced measurement resolution in two measurement applications.
Single photon measurements: Quantum State Discrimination—Using single-photon detection and an adaptive measurement strategy, we are able to determine the state of an optical pulse with errors below what is possible with even the best possible passive …
Single photon measurements: Single Photon Tunneling—We use light created two photons at a time to explore the time needed to cross a barrier. The extreme simultaneity of creation of the two photons allows for very precise timing of optical delays. …
Sources, detectors and metrology—We develop and learn how to characterize non-classical sources and single-photon detectors. It turns out that it is not enough to characterize detectors of single photons by detection efficiency …
Quantum Biophotonics—Faint light detection is a staple in biology- used from systems biology research to bioassays for biomanufacturing and healthcare diagnostics.
Memory—Critical to quantum information applications is the need to store a quantum state while other qbits are created or processed.
Universal Quantum Bus—If quantum computers are ever to be realized, they likely will be made of different types of parts that will need to share information with one another, just like the memory and logic circuits in …
Applications of Quantum Information—Theory is being developed and used to devise methods for preserving and exploiting the quantum behavior of ever-larger systems for metrology, communication, and information processing.
