Thermality versus objectivity: Can they peacefully coexist? (2021)
Journal Article
Le, T. P., Winter, A., & Adesso, G. (2021). Thermality versus objectivity: Can they peacefully coexist?. Entropy, 23(11), Article 1506. https://doi.org/10.3390/e23111506

Under the influence of external environments, quantum systems can undergo various different processes, including decoherence and equilibration. We observe that macroscopic objects are both objective and thermal, thus leading to the expectation that b... Read More about Thermality versus objectivity: Can they peacefully coexist?.

General Expressions for the Quantum Fisher Information Matrix with Applications to Discrete Quantum Imaging (2021)
Journal Article
Fiderer, L. J., Tufarelli, T., Adesso, G., & Piano, S. (2021). General Expressions for the Quantum Fisher Information Matrix with Applications to Discrete Quantum Imaging. PRX Quantum, 2(2), Article 020308. https://doi.org/10.1103/prxquantum.2.020308

The quantum Fisher information matrix is a central object in multiparameter quantum estimation theory. It is usually challenging to obtain analytical expressions for it because most calculation methods rely on the diagonalization of the density matri...

Quantum secure learning with classical samples (2021)
Journal Article
Song, W., Lim, Y., Kwon, H., Adesso, G., Wieśniak, M., Pawłowski, M., …Bang, J. (2021). Quantum secure learning with classical samples. Physical Review A, 103(4), Article 042409. https://doi.org/10.1103/physreva.103.042409

Studies addressing the question “Can a learner complete the learning securely?” have recently been spurred from the standpoints of fundamental theory and potential applications. In the relevant context of this question, we present a classical-quantum... Read More about Quantum secure learning with classical samples.

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, 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.
