Molecular ensemble-based remote quantum storage for charge qubit via a quasidark state
H. R. Zhang, Yingfang Gao, Zongping Gong, C. P. Sun · Physical Review A · 2009
We propose a quantum storage scheme independent of the current time-control schemes and study a ``quantum data bus'' (transmission line resonator) in a hybrid system consisting of a circuit QED system integrated with a cold molecular ensemble. Here, an effective interaction between the charge qubit and molecules is mediated by the off-resonant field in the data bus. Correspondingly, the charge state can be mapped into the collective quasispin state of the molecular ensemble via the standard dark-state-based adiabatic manipulation.
