The longest storage time of light energy
6 FAQs about [The longest storage time of light energy]
Which atom has the longest optical storage time?
To date, the longest optical storage time is ~1 min realized in 87 Rb atoms 13 and a Pr 3+:Y 2 SiO 5 crystal using the electromagnetically induced transparency protocol 10. For single-photon-level storage, the longest storage time is ~1 s realized in 87 Rb atoms 14.
What is light storage?
Provided by the Springer Nature SharedIt content-sharing initiative Light storage, the controlled and reversible mapping of photons onto long-lived states of matter, enables memory capability in optical quantum networks. Prominent storage media are warm alkali vapors due to their strong optical coupling and long-lived spin states.
What is light storage on the time scale of a minute?
Phys. Rev. A 87, 031801 (R) (2013) - Light storage on the time scale of a minute Phys. Rev. A 87, 031801 (R) – Published 6 March 2013 Light storage on the minute scale is an important capability for future scalable quantum information networks spanning intercontinental distances.
Is light storage a scalable quantum information network spanning intercontinental distances?
Phys. Rev. A 87, 031801 (R) – Published 6 March 2013 Light storage on the minute scale is an important capability for future scalable quantum information networks spanning intercontinental distances. We employ an ultracold atomic gas confined in a one-dimensional optical lattice for long-term light storage.
Can atomic gas confined in a one-dimensional optical lattice be used for long-term light storage?
We employ an ultracold atomic gas confined in a one-dimensional optical lattice for long-term light storage. The differential ac Stark shift of the ground-level microwave transition used for storage is reduced to a sub-Hz level by the application of a magic-valued magnetic field.
Why is long-lived optical storage a challenge?
Although hours of spin coherence time have been demonstrated, long-lived optical storage remains a challenge because of the complicated and unknown energy structures in ZEFOZ fields 9, 10, 11 and a reduced effective absorption in magnetic fields 12 because only one subsite can be used for the long-term storage 11.
