News and Updates

NIST chip containing a single-photon detector made of superconducting nanowires. Four chips like this were used in the experiment that entangled three photons.

Unity in the Photon Community

The creation and detection of single photons (the smallest units of light) has grown in a few decades from an experimental laboratory pursuit to an important

Applications of Quantum Information

Ongoing
Theory is being developed and used to devise methods for preserving and exploiting the quantum behavior of ever-larger systems for metrology, communication, and
rare earth ions in a host crystal

Memory

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