Coherence manipulation with dephasing-covariant operations
Bartosz Regula, Varun Narasimhachar, Francesco Buscemi +1
We characterize the operational capabilities of quantum channels which can neither create nor detect quantum coherence vis-à-vis efficiently manipulating coherence as a resource. W…
One-shot entanglement distillation beyond local operations and classical communication
Bartosz Regula, Kun Fang, Xin Wang +1
We study the task of entanglement distillation in the one-shot setting under different classes of quantum operations which extend the set of local operations and classical communic…
General Resource Theories in Quantum Mechanics and Beyond: Operational Characterization via Discrimination Tasks
Ryuji Takagi, Bartosz Regula
We establish an operational characterization of general convex resource theories -- describing the resource content of not only states, but also measurements and channels, both wit…
Strong monogamy inequalities for four qubits
Bartosz Regula, Andreas Osterloh, Gerardo Adesso
We investigate possible generalizations of the Coffman-Kundu-Wootters monogamy inequality to four qubits, accounting for multipartite entanglement in addition to the bipartite term…
