Abstract

Manipulation of qubits using continuous-variable (CV) technologies to combine the strengths and mitigate the weaknesses of either approach is a new branch in quantum information processing with the potential to enable high-fidelity, highly efficient, deterministic universal quantum computation [1]. Promising as it is, to realize a quantum computer using this hybrid technique, quantum error correction of the most dominant, detrimental yet inevitable error, photon loss, is nevertheless required. Towards introducing redundancy in the encoded information of a qubit, by encoding it into a multi-photon superposition manipulable with CV technologies, we generate general biphoton 2-mode time-bin qutrits that are compatible with homodyne measurements.
