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…

Quantum steganographic protocols using degenerate and entanglement-assisted quantum codes
Sanjoy Dutta, Nihar Ranjan Dash, Subhashish Banerjee +1
Steganography is the art of concealing secret information by embedding it in an apparently innocent-looking message. Quantum steganography applies the principles of quantum mechani…

Bounds on concatenated entanglement-assisted quantum error-correcting codes
Nihar Ranjan Dash, Sanjoy Dutta, R. Srikanth +1
Code concatenation combines two or more component codes to design larger codes with greater noise resilience. Introducing entanglement assistance to concatenated codes provides a f…
