Linear-optical encoded GHZ measurements and fault-tolerant quantum computation and communication

Methods and systems are provided for performing an encoded -qubit GHZ measurement on encoded (logical) qubits using encoded Bell state measurements (E-BSMs). Each E-BSM comprises a plurality of dual-rail Bell state measurements (DR-BSMs) performed on pairs of dual-rail encoded photonic qubits (DR-qu...

Zusammenfassung:Methods and systems are provided for performing an encoded -qubit GHZ measurement on encoded (logical) qubits using encoded Bell state measurements (E-BSMs). Each E-BSM comprises a plurality of dual-rail Bell state measurements (DR-BSMs) performed on pairs of dual-rail encoded photonic qubits (DR-qubits). Methods and systems for using encoded -qubit GHZ measurements for fault-tolerant measurement-based quantum computation are also provided.
