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…
Quantum interpretations, causality and quantum computation
Vivek Kumar, M. P. Singh, R. Srikanth
The interpretation of quantum mechanics continues to be debated, and quantum nonlocality accentuates the puzzle. Quantum interpretations can be classified broadly into two types: r…
Concatenating quantum error-correcting codes with decoherence-free subspaces and vice versa
Nihar Ranjan Dash, Sanjoy Dutta, R. Srikanth +1
Quantum error-correcting codes (QECCs) and decoherence-free subspace (DFS) codes provide active and passive means, respectively, to address certain types of errors that arise durin…
Supergranular Fractal Dimension and Solar Rotation
Sowmya G. M., Rajani G., U. Paniveni +1
We present findings from an analysis of the fractal dimension of solar supergranulation as a function of latitude, supergranular cell size and solar rotation, employing spectroheli…
