14 Jan 2016 | Abstract: | We study the protection of subradiant states by the symmetry of the atomic
distributions in the Dicke limit, in which collective Lamb shift cannot be
neglected. We find that anti-symmetric states are subradiant states for
distribution with reflection symmetry. These states can be prepared by
anti-symmetric optical modes and converted to superradiant states by properly
tailored 2pipulses. Continuous symmetry can also be used to achieve
subradiance. This study is relevant to the problem of robust quantum memory
with long storage time and fast readout. | Source: | arXiv, 1601.3441 | Services: | Forum | Review | PDF | Favorites |
