An environment-mediated quantum deleter
R. Srikanth, Subhashish Banerjee
Environment-induced decoherence presents a great challenge to realizing a quantum computer. We point out the somewhat surprising fact that decoherence can be useful, indeed necessa…
Geometric Phase of a qubit interacting with a squeezed-thermal bath
Subhashish Banerjee, R. Srikanth
We study the geometric phase of an open two-level quantum system under the influence of a squeezed, thermal environment for both non-dissipative as well as dissipative system-envir…
Symmetries and noise in quantum walk
C. M. Chandrashekar, R. Srikanth, Subhashish Banerjee
We study some discrete symmetries of unbiased (Hadamard) and biased quantum walk on a line, which are shown to hold even when the quantum walker is subjected to environmental effec…
The quantum measurement problem and physical reality: a computation theoretic perspective
R. Srikanth
Is the universe computable? If yes, is it computationally a polynomial place? In standard quantum mechanics, which permits infinite parallelism and the infinitely precise specifica…
The quantum measurement problem as a witness to "It from bit"
R. Srikanth
A conceptual difficulty in the foundations of quantum mechanics is the quantum measurement problem (QMP), essentially concerned with the apparent non-unitarity of the measurement p…
