Quantifying the particle aspect of quantum systems
Sreetama Das, Indranil Chakrabarty, Arun Kumar Pati +2
The possibility of a quantum system to exhibit properties that are akin to both the classically held notions of being a particle and a wave, is one of the most intriguing aspects o…
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…
Protocol for unambiguous quantum state discrimination using quantum coherence
Sunho Kim, Longsuo Li, Asutosh Kumar +5
Roa et al. showed that quantum state discrimination between two nonorthogonal quantum states does not require quantum entanglement but quantum dissonance only. We find that quantum…
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…
