In early 2025, special signals wended their way through a fiber-optic highway strung above the streets and sidewalks of the Maryland suburbs.
Key facts
- Over a 24-hour period, the researchers were able to distribute entangled photons 92.8% of the time, needing only 7.2% of the time for correcting polarizations
- The experiment did not break a record for long-distance entanglement; a European group in 2022 distributed entangled photons over 248 kilometers of underground fiber
- National Institute of Standards and Technology (NIST) researchers and collaborators reported this advance in the Journal of Optical Communications and Networking
- So a team of researchers from NIST, the Joint Quantum Institute (a partnership between NIST and the University of Maryland) and the New York-based company Qunnect set out to test whether quantum
Summary
National Institute of Standards and Technology (NIST) researchers and collaborators reported this advance in the Journal of Optical Communications and Networking. Quantum networks depend on a special phenomenon called entanglement. These long-distance links could reshape fields from astronomy to seismology to drug discovery. Networks of entangled quantum computers, meanwhile, might someday crunch algorithms too complex for any single device, helping scientists simulate potential new drugs and materials.
