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…
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…
A note on cohering power and de-cohering power
Kaifeng Bu, Chunhe Xiong
Cohering power and de-cohering power have recently been proposed to quantify the ability of a quantum operation to produce and erase coherence respectively. In this paper, we inves…
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…
