Partially Unraveling an Entangled Mystery

Entanglement—a uniquely quantum phenomenon that intimately links the fate of subatomic particles even if they reside on opposite sides of the galaxy—is a key
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

When Atoms Don’t Blend In

Researchers from the National Institute of Standards and Technology (NIST) and colleagues at the Joint Quantum Institute (JQI) have prepared and controlled a
non-linear crystal

Driving the Universal Quantum Bus

NIST scientists have achieved a world record in detecting the intensity of an ultra-faint source of light, equaling the capabilities of the deep-space

Photons by the Numbers

A NIST team is at work on what promises to be one of the world's most accurate methods for generating a specified number of photons, and has devised a method to
