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…
Signaling versus distinguishing different superpositions of same pure quantum state
Chirag Srivastava, Sreetama Das, Aditi Sen De +1
Different ensembles of quantum states can have the same average nonpure state. Distinguishing between such constructions, via different mixing procedures of the same nonpure quantu…
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…
