Nonlocality as a consequence of complementarity
Hai Wang, Asutosh Kumar, Junde Wu
Complementarity and nonlocality are two characteristic traits of quantum physics that distinguishes it from classical physics. In this paper, we prove that the complementarity betw…
Field extension of real values of physical observables in classical theory can help attain quantum results
Hai Wang, Asutosh Kumar, Junde Wu +1
Physical quantities are assumed to take real values, which stems from the fact that an usual measuring instrument that measures a physical observable always yields a real number. H…
Resource Theory of Special Antiunitary Asymmetry
Kaifeng Bu, Heng Fan, Arun Kumar Pati +1
We propose the resource theory of a special antiunitary asymmetry in quantum theory. The notion of antiunitary asymmetry, in particular, -asymmetry is different from the…
The geometry properties of parity and time reversal operators in two dimensional spaces
Minyi Huang, Yu Yang, Junde Wu +1
The parity operator and time reversal operator are two important operators in the quantum theory, in particular, in the -symmetric quantum theory. By usi…
Coherence breaking channels and coherence sudden death
Kaifeng Bu, Swati, Uttam Singh +1
Quantum noise is ubiquitous to quantum systems as they incessantly interact with their surroundings and results in degrading useful resources such as coherence for single quantum s…
Average distance of random pure states from maximally entangled and coherent states
Kaifeng Bu, Uttam Singh, Lin Zhang +1
It is well known that random bipartite pure states are typically maximally entangled within an arbitrarily small error. Showing that the marginals of random bipartite pure states a…
Bell-type inequality in quantum coherence theory as an entanglement witness
Kaifeng Bu, Asutosh Kumar, Junde Wu
Bell inequality is a mathematical inequality derived using the assumptions of locality and realism. Its violation guarantees the existence of quantum correlations in a quantum stat…
Products of weak values: uncertainty relations, complementarity and incompatibility
Michael J. W. Hall, Arun Kumar Pati, Junde Wu
The products of weak values of quantum observables are shown to be of value in deriving quantum uncertainty and complementarity relations, for both weak and strong measurement stat…
