Concept of orbital entanglement and correlation in quantum chemistry
Lexin Ding, Sam Mardazad, Sreetama Das +4
A recent development in quantum chemistry has established the quantum mutual information between orbitals as a major descriptor of electronic structure. This has already facilitate…
Resource theory of quantum coherence with probabilistically non-distinguishable pointers and corresponding wave-particle duality
Chirag Srivastava, Sreetama Das, Ujjwal Sen
One of the fundamental features of quantum mechanics is the superposition principle, a manifestation of which is embodied in quantum coherence. Coherence of a quantum state is inva…
Quantum Process Randomness
Sreetama Das, Asutosh Kumar, Aditi Sen De +1
We study the optimization of any quantum process by minimizing the "randomness" in the measurement result at the output of that quantum process. We conceptualize and propose a meas…
Interference-induced localization in quantum random walk on clean cyclic graph
Jayanth Jayakumar, Sreetama Das, Aditi Sen De +1
We quantitatively differentiate between the spreads of discrete-time quantum and classical random walks on a cyclic graph. Due to the closed nature of any cyclic graph, there is ad…
Partial coherence and quantum correlation with fidelity and affinity distances
Chunhe Xiong, Asutosh Kumar, Minyi Huang +3
A fundamental task in any physical theory is to quantify certain physical quantity in a meaningful way. In this paper we show that both fidelity distance and affinity distance sati…
Inhibition of spreading in quantum random walks due to quenched Poisson-distributed disorder
Sreetama Das, Shiladitya Mal, Aditi Sen De +1
We consider a quantum particle (walker) on a line who coherently chooses to jump to the left or right depending on the result of toss of a quantum coin. The lengths of the jumps ar…
