Mixing indistinguishable systems leads to a quantum Gibbs paradox (2021)
Journal Article
Yadin, B., Morris, B., & Adesso, G. (2021). Mixing indistinguishable systems leads to a quantum Gibbs paradox. Nature Communications, 12(1), Article 1471. https://doi.org/10.1038/s41467-021-21620-7

The classical Gibbs paradox concerns the entropy change upon mixing two gases. Whether an observer assigns an entropy increase to the process depends on their ability to distinguish the gases. A resolution is that an "ignorant" observer, who cannot d... Read More about Mixing indistinguishable systems leads to a quantum Gibbs paradox.

Entanglement between Identical Particles Is a Useful and Consistent Resource (2020)
Journal Article
Morris, B., Yadin, B., Fadel, M., Zibold, T., Treutlein, P., & Adesso, G. (2020). Entanglement between Identical Particles Is a Useful and Consistent Resource. Physical Review X, 10(4), Article 041012. https://doi.org/10.1103/physrevx.10.041012

The existence of fundamentally identical particles represents a foundational distinction between classical and quantum mechanics. Due to their exchange symmetry, identical particles can appear to be entangled - another uniquely quantum phenomenon wit...

© 2019 American Physical Society. Quantum systems can be exploited for disruptive technologies but in practice quantum features are fragile due to noisy environments. Quantum coherence, a fundamental such feature, is a basis-dependent property that i... Read More about Demonstrating Quantum Coherence and Metrology that is Resilient to Transversal Noise.

Pushing the limits of the reaction-coordinate mapping (2019)
Journal Article

The reaction-coordinate mapping is a useful technique to study complex quantum dissipative dynamics into structured environments. In essence, it aims to mimic the original problem by means of an “augmented system,” which includes a suitably chosen co... Read More about Pushing the limits of the reaction-coordinate mapping.

Extendibility of bosonic Gaussian states (2019)
Journal Article
Lami, L., Khatri, S., Adesso, G., & M. Wilde, M. (2019). Extendibility of bosonic Gaussian states. Physical Review Letters, 123(5), Article 050501. https://doi.org/10.1103/PhysRevLett.123.050501

Extendibility of bosonic Gaussian states is a key issue in continuous-variable quantum information. We show that a bosonic Gaussian state is k-extendible if and only if it has a Gaussian k-extension, and we derive a simple semidefinite program, whose...

Operational advantage of quantum resources in subchannel discrimination (2019)
Journal Article

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.

Generic emergence of objectivity of observables in infinite dimensions (2018)
Journal Article
Knott, P. A., Tufarelli, T., Piani, M., & Adesso, G. (2018). Generic emergence of objectivity of observables in infinite dimensions. Physical Review Letters, 121(16), https://doi.org/10.1103/PhysRevLett.121.160401

Quantum Darwinism posits that information becomes objective whenever multiple observers indirectly probe a quantum system by each measuring a fraction of the environment. It was recently shown that objectivity of observables emerges generically from... Read More about Generic emergence of objectivity of observables in infinite dimensions.

Certification and quantification of multilevel quantum coherence (2018)
Journal Article

Quantum coherence, present whenever a quantum system exists in a superposition of multiple classically distinct states, marks one of the fundamental departures from classical physics. Quantum coherence has recently been investigated rigorously within... Read More about Certification and quantification of multilevel quantum coherence.

We consider frequency estimation in a noisy environment with noisy probes. This builds on previous studies, most of which assume that the initial probe state is pure, while the encoding process is noisy, or that the initial probe state is mixed, whil...
