Generation of a time-frequency grid state with integrated biphoton frequency combs
Generation of a time-frequency grid state with integrated biphoton frequency combs
Encoding quantum information in continuous variables is intrinsically faulty. Nevertheless, redundant qubits can be used for error correction, as proposed by Gottesman et al. [Phys. Rev. A 64 012310 (2001)]. We show how to experimentally implement this encoding using time-frequency continuous degrees of freedom of photon pairs produced by spontaneous …
