Engineering two-photon wavefunction and statistics in a semiconductor chip (Conference Presentation)
Résumé
Encoding quantum information in continuous variables is intrinsically faulty. Nevertheless, redundant qubits can be used for error correction, as proposed in [1]. We show how to experimentally implement this encoding using time-frequency continuous de- grees of freedom of photon pairs produced by spontaneous parametric down conversion. We illustrate our results using an integrated AlGaAs photon-pair source. We show how sin- gle qubit gates can be implemented and finally propose a theoretical scheme for correcting errors in a circuit-like and in a measurement-based architecture.
