Abstract: | This paper proposes a scheme for information concentration of two remote two-level
atoms in cavity QED. This scheme does not involve the Bell-state measurement. During
the interaction between atom and cavity, the cavity frequency is large-detuned from
the atomic transition frequency, thus the scheme is insensitive to both the cavity
decay and the thermal field. This idea can directly be generalized in the case of
multi-atom information concentration. |
