Entangling single- and N -atom qubits for fast quantum state detection and transmission
Mark E. Saffman, Thad G Walker · Physical Review A · 2005
We discuss the use of Rydberg blockade techniques for entanglement of single-atom qubits with collective $N$-atom qubits. We show how the entanglement can be used to achieve fast readout and transmission of the state of single-atom qubits without the use of optical cavities.
