Abstract

In quantum computing, atomic ensembles can efficiently map ``flying'' photonic qubits onto stationary qubits. These absorbed photons, however, end up encoded in delocalized states that preclude local processing. A new concept called a ``quantum spin lens'' could focus delocalized excitations onto a single atom, which can then be manipulated using standard quantum computing tools.
