Using single-photon detection and an adaptive measurement strategy, we determine the state of an optical pulse with errors below what is possible with even the

Measuring Light-Matter Interactions in Chip-Based Optical Cavities

Measuring interactions between light and matter has both fundamental and practical importance. For example, lasers have had a profound influence on science and

Memory

Critical to quantum information applications is the need to store a quantum state while other qbits are created or processed.

Micro- and nano-optomechanical systems

Light can interact with mechanical systems in interesting and useful ways, not only probing the mechanical motion with spectacular sensitivity, but also driving

Nanostructure Fabrication and Metrology

Single photons are the fundamental particles for all optical measurements. Single photon detectors made from avalanche photodiodes or photomultiplier tubes are

Image depiction of: To connect two nodes operating at different wavelengths, there are generally two strategies: (1) use quantum frequency conversion or quantum transduction to convert the wavelength of the photon emitted by one node to the wavelength of the second node, or (2) connect the two nodes using an entangled photon pair source whose two photons have wavelengths that match the two nodes. Both techniques involve nonlinear optics.

Nonlinear Optics for Quantum Information and Networking

Nonlinear optics offer ways to control and engineer the interconnects in a quantum network. In a hybrid quantum network where the quantum nodes operate at
