Qubit ZooEarly proposal for quantum computation using linear optical components. Shows how to translate quantum circuits into optical implementations using beam splitters, phase shifters, and photon detectors. Represents multiple qubits using a single photon in multiple modes (dual-rail encoding). Demonstrates the method with an optical implementation of Brassard et al.’s teleportation circuit.

- Constructive method to map quantum circuits to linear optical implementations
- Multi-qubit encoding using single photons across multiple spatial modes
- Demonstrated with 3-qubit teleportation circuit
- Uses only present-day optical components (beam splitters, phase shifters)
