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
