QUANTUM MEMORY

My partner sometimes accuses me of having a “quantum memory” when I can’t fully recall something previously said or promised. Today’s post, however, is about a different kind of Quantum Memory.

In the Physics section of SCIENCEALERT, David Nield reports, “In New Milestone, Physicists Store And Transport Light Using Quantum Memory.” The article describes an important advancement over “electromagnetically induced transparency” (EIT) where individual atoms have been used to trap, map, store and move light pulses within a storage device. We’re talking trapping, mapping, storing, recalling and transporting quantum light information over distances greater than the storage device. And we’re not talking absolute zero cold magnetic bottles here.

Photons carrying information are translated into electron cloud excitation states that can me moved in photon-electron packets called polaritons across distances, de-translating them back into photons carrying the same information. The underpinnings of Q-trans as appears in THE EDGE OF MADNESS (Aignos 2020) by Raymond Gaynor.
