Abstract:We present a scheme for the demonstration of a 1-atom based single-photon
switch, utilizing cavity-QED with toroidal micro-resonators.
Practical single-photon switching, namely controlling the direction of one
single-photon pulse with a control field that is another single-photon
pulse, has not been achieved experimentally to date.
The device we propose will also function as a 1-qbit quantum memory,
enabling a deterministic quantum state transfer between a single photon and
an atom, with no need for any control field.
