Qubit ZooConstructive early linear-optical quantum computing proposal that maps quantum circuits onto beam splitters, phase shifters, and photon detectors. It treats qubits as single-photon occupation states across multiple optical modes, making the dual-rail / multi-rail encoding explicit well before modern photonic fault-tolerance architectures.
Key Results
- Gives a direct recipe for translating quantum circuits into linear-optical networks
- Uses single-photon occupation across multiple modes as the computational encoding
- Works through an optical implementation of teleportation-style circuits
- Shows that useful quantum-information processing was already accessible in passive optical hardware plus detection
