Flying qubit

WebIn today's technology, the only practical flying qubit is a photon. Thus, the protocol relies on reliable single-photon transmission. \(\rhd\) Which is hard to do, but has been demonstrated over distances beyond 100km. The protocol also relies on being able to produce truly random bits: This is easy with quantum technology. WebSep 1, 2024 · In these flying-qubit control problems, we are mainly concerned with quantum input–output processes of flying qubits steered by classical time-dependent control functions. The classical control functions may be either coherent (e.g., a semi-classical driving field) or incoherent (e.g., tunable waveguide coupling) in the sense that …

WebJan 25, 2024 · The qubits, whose photon-emission frequencies are tunable, interact with the photonic states of the waveguide. When a qubit’s frequency falls within the band gap, there are no propagating modes to which the quibit excitation can couple. As a result, the excitation creates a “bound state” that remains localized around the qubit (Fig. 1 ). WebSep 1, 2024 · Fig. 1.
