Decohered toric code under quantum damping noise and its mapping to a classical spin model
Nihar Ranjan Dash, Sanjoy Dutta, R. Srikanth +1
We investigate properties of toric codes under realistic damping error channels, which include squeezing, thermal and non-Markovian effects. First, we map the decohered toric code…

Entanglement-assisted continuous-variable concatenated codes for encoding qubits or oscillators
Nihar Ranjan Dash, Sanjoy Dutta, R. Srikanth +1
Entanglement-assisted (EA) stabilizer codes enhance the rate of error correction in relation to codes with no pre-shared entanglement. Meanwhile, bosonic error-correcting codes, su…
