Continuous variables error correction with integrated biphoton frequency combs

2019 · arXiv (Cornell University)

Encoding quantum information in continuous variables is intrinsically faulty. Nevertheless, redundant qubits can be used for error correction, as proposed by Gottesman, Kitaev and Preskill in Phys. Rev. A \textbf{64} 012310, (2001). We show how …

On-chip generation of hybrid polarization-frequency entangled biphoton states

2022 · Photonics Research

We demonstrate a chip-integrated semiconductor source that combines polarization and frequency entanglement, allowing the generation of entangled biphoton states in a hybrid degree of freedom without post-manipulation. Our AlGaAs device is based on type-II spontaneous …
