Qubit ZooIntroduces the time-bin encoding scheme for photonic qubits, where quantum information is encoded in the arrival time of a photon within two well-defined time windows (early/late). Demonstrates entanglement between time-bin encoded photon pairs from parametric downconversion.
Key Results
- First demonstration of time-bin entangled photon pairs
- Encoding is robust against polarization decoherence in optical fibers
- Uses unbalanced Mach-Zehnder interferometers for preparation and analysis
- Became the standard encoding for long-distance quantum communication
