Indistinguishability-enabled coherence for quantum metrology (2019)
Journal Article
Castellini, A., Lo Franco, R., Lami, L., Winter, A., Adesso, G., & Compagno, G. (2019). Indistinguishability-enabled coherence for quantum metrology. Physical Review A, 100(1), Article 012308. https://doi.org/10.1103/physreva.100.012308

Quantum coherence plays a fundamental and operational role in different areas of physics. A resource theory has been developed to characterize the coherence of distinguishable particles systems. Here we show that indistinguishability of identical par... Read More about Indistinguishability-enabled coherence for quantum metrology.

Generic bound coherence under strictly incoherent operations (2019)
Journal Article
Lami, L., Regula, B., & Adesso, G. (2019). Generic bound coherence under strictly incoherent operations. Physical Review Letters, 122(15), Article 150402. https://doi.org/10.1103/physrevlett.122.150402

We compute analytically the maximal rates of distillation of quantum coherence under strictly incoherent operations (SIO) and physically incoherent operations (PIO), showing that they coincide for all states, and providing a complete description of t...

Towards superresolution surface metrology: quantum estimation of angular and axial separations (2019)
Journal Article
Napoli, C., Piano, S., Leach, R., Adesso, G., & Tufarelli, T. (2019). Towards superresolution surface metrology: quantum estimation of angular and axial separations. Physical Review Letters, 122(14), Article 140505. https://doi.org/10.1103/physrevlett.122.140505

We investigate the localization of two incoherent point sources with arbitrary angular and axial separations in the paraxial approximation. By using quantum metrology techniques, we show that a simultaneous estimation of the two separations is achiev...

Assisted work distillation (2019)
Journal Article
Morris, B., Lami, L., & Adesso, G. (2019). Assisted work distillation. Physical Review Letters, 122(13), Article 130601. https://doi.org/10.1103/physrevlett.122.130601

We study the process of assisted work distillation. This scenario arises when two parties share a bipartite quantum state ρAB and their task is to locally distill the optimal amount of work when one party is restricted to thermal operations, whereas... Read More about Assisted work distillation.

Activation and superactivation of single-mode Gaussian quantum channels (2019)
Journal Article
Lim, Y., Takagi, R., Adesso, G., & Lee, S. (2019). Activation and superactivation of single-mode Gaussian quantum channels. Physical Review A, 99(3), Article 032337. https://doi.org/10.1103/physreva.99.032337

Activation of quantum capacity is a surprising phenomenon according to which the quantum capacity of a certain channel may increase by combining it with another channel with zero quantum capacity. Superactivation describes an even more particular occ... Read More about Activation and superactivation of single-mode Gaussian quantum channels.

State exchange with quantum side information (2019)
Journal Article
Lee, Y., Takagi, R., Yamasaki, H., Adesso, G., & Lee, S. (2019). State exchange with quantum side information. Physical Review Letters, 122(1), Article 010502. https://doi.org/10.1103/physrevlett.122.010502

We consider a quantum communication task between two users Alice and Bob, in which Alice and Bob exchange their respective quantum information by means of local operations and classical communication assisted by shared entanglement. Here, we assume t... Read More about State exchange with quantum side information.
