| Quantum physics: Record entanglement of quantum memories Posted: 07 Jul 2022 07:09 AM PDT Researchers have entangled two quantum memories over a 33-kilometer-long fiber optic connection -- a record and an important step toward the quantum internet. |
| Processing photons in picoseconds Posted: 27 Jun 2022 09:50 AM PDT To build novel quantum devices, researchers need to be able to control individual photons of light: Engineers propose doing so with a time lens. Like a magnifying glass zooming in on a spatial feature, this device 'magnifies' time and enabled the team to identify single photons from a larger laser beam at picosecond resolution -- that's 70x faster than has been observed with other types of single-photon detectors. |
