Mixed Form of Ambiguous and Unambiguous Discriminations
Sunho Kim, Junde Wu, Minhyung Cho
In this paper, we introduce a mixed form of ambiguous and unambiguous quantum state discriminations, and show that the mixed form has higher success probability than the unambiguou…
Catalytic coherence transformations
Kaifeng Bu, Uttam Singh, Junde Wu
Catalytic coherence transformations allow the otherwise impossible state transformations using only incoherent operations with the aid of an auxiliary system with finite coherence…
Logically reversible measurements: Construction and application
Sunho Kim, Juncheng Wang, Asutosh Kumar +2
We show that for any von Neumann measurement, we can construct a logically reversible measurement such that Shannon entropies and quantum discords induced by the two measurements h…
Cohering power of quantum operations
Kaifeng Bu, Asutosh Kumar, Lin Zhang +1
Quantum coherence is a basic feature of quantum physics. Combined with tensor product structure of state space, it gives rise to the novel concepts such as entanglement and quantum…
The Decomposition Properties of Quantum Discord
Sunho Kim, Junde Wu
The quantum discord was introduced by Ollivier, Zurek, Henderson and Vedral as an indicator of the degree of quantumness of mixed states. In this paper, we give out the decompositi…
