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...

Operational advantage of quantum resources in subchannel discrimination (2019)
Journal Article
Takagi, R., Regula, B., Bu, K., Liu, Z., & Adesso, G. (2019). Operational advantage of quantum resources in subchannel discrimination. Physical Review Letters, 122(14), Article 140402. https://doi.org/10.1103/physrevlett.122.140402

One of the central problems in the study of quantum resource theories is to provide a given resource with an operational meaning, characterizing physical tasks in which the resource can give an explicit advantage over all resourceless states. We show... Read More about Operational advantage of quantum resources in subchannel discrimination.

Gaussian quantum resource theories (2018)
Journal Article
Lami, L., Regula, B., Wang, X., Nichols, R., Winter, A., & Adesso, G. (2018). Gaussian quantum resource theories. Physical Review A, 98(2), https://doi.org/10.1103/physreva.98.022335

We develop a general framework to assess capabilities and limitations of the Gaussian toolbox in continuous-variable quantum information theory. Our framework allows us to characterize the structure and properties of quantum resource theories special... Read More about Gaussian quantum resource theories.

Probabilistic distillation of quantum coherence (2018)
Journal Article
Fang, K., Wang, X., Lami, L., Regula, B., & Adesso, G. (2018). Probabilistic distillation of quantum coherence. Physical Review Letters, 121(7), doi:10.1103/physrevlett.121.070404. ISSN 0031-9007

The ability to distill quantum coherence is pivotal for optimizing the performance of quantum technologies; however, such a task cannot always be accomplished with certainty. Here we develop a general framework of probabilistic distillation of quantu... Read More about Probabilistic distillation of quantum coherence.

One-Shot Coherence Distillation (2018)
Journal Article
Regula, B., Fang, K., Wang, X., & Adesso, G. (2018). One-Shot Coherence Distillation. Physical Review Letters, 121(1), https://doi.org/10.1103/PhysRevLett.121.010401

We characterize the distillation of quantum coherence in the one-shot setting, that is, the conversion of general quantum states into maximally coherent states under different classes of quantum operations. We show that the maximally incoherent opera... Read More about One-Shot Coherence Distillation.

Accessible bounds for general quantum resources (2018)
Journal Article
Bromley, T. R., Cianciaruso, M., Vourekas, S., Regula, B., & Adesso, G. (2018). Accessible bounds for general quantum resources. Journal of Physics A: Mathematical and Theoretical, 51(32), https://doi.org/10.1088/1751-8121/aacb4a

The recent development of general quantum resource theories has given a sound basis for the quantification of useful quantum effects. Nevertheless, the evaluation of a resource measure can be highly non-trivial, involving an optimisation that is ofte... Read More about Accessible bounds for general quantum resources.

Converting multilevel nonclassicality into genuine multipartite entanglement (2018)
Journal Article
Regula, B., Piani, M., Cianciaruso, M., Bromley, T. R., Streltsov, A., & Adesso, G. (2018). Converting multilevel nonclassicality into genuine multipartite entanglement. New Journal of Physics, 20, Article 033012. https://doi.org/10.1088/1367-2630/aaae9d

Characterizing genuine quantum resources and determining operational rules for their manipulation are crucial steps to appraise possibilities and limitations of quantum technologies. Two such key resources are nonclassicality, manifested as quantum s... Read More about Converting multilevel nonclassicality into genuine multipartite entanglement.

Geometric approach to entanglement quantification with polynomial measures (2016)
Journal Article
Regula, B., & Adesso, G. (2016). Geometric approach to entanglement quantification with polynomial measures. Physical Review A, 94(2), Article 022324. https://doi.org/10.1103/PhysRevA.94.022324

We show that the quantification of entanglement of any rank-2 state with any polynomial entanglement measure can be recast as a geometric problem on the corresponding Bloch sphere. This approach provides insight into the properties of entanglement an... Read More about Geometric approach to entanglement quantification with polynomial measures.

Strong monogamy inequalities for four qubits (2016)
Journal Article
Regula, B., Osterloh, A., & Adesso, G. (2016). Strong monogamy inequalities for four qubits. Physical Review A, 93(5), Article 052338. https://doi.org/10.1103/PhysRevA.93.052338

We investigate possible generalizations of the Coffman-Kundu-Wootters monogamy inequality to four qubits, accounting for multipartite entanglement in addition to the bipartite terms. We show that the most natural extension of the inequality does not... Read More about Strong monogamy inequalities for four qubits.

Entanglement quantification made easy: polynomial measures invariant under convex decomposition (2016)
Journal Article
Regula, B., & Adesso, G. (2016). Entanglement quantification made easy: polynomial measures invariant under convex decomposition. Physical Review Letters, 116, Article 070504. https://doi.org/10.1103/PhysRevLett.116.070504

Quantifying entanglement in composite systems is a fundamental challenge, yet exact results are only available in few special cases. This is because hard optimization problems are routinely involved, such as finding the convex decomposition of a mixe...

Journal Article
Regula, B., Lee, A. R., Dragan, A., & Fuentes, I. (2016). Generating entanglement between two-dimensional cavities in uniform acceleration. Physical Review D, 93(2), Article 025034. https://doi.org/10.1103/physrevd.93.025034

Moving cavities promise to be a suitable system for relativistic quantum information processing. It has been shown that an inertial and a uniformly accelerated one-dimensional cavity can become entangled by letting an atom emit an excitation while it...
