Upper Bounds on the Distillable Randomness of Bipartite Quantum States
Ludovico Lami, Bartosz Regula, Xin Wang +1
The distillable randomness of a bipartite quantum state is an information-theoretic quantity equal to the largest net rate at which shared randomness can be distilled from the stat…
Functional analytic insights into irreversibility of quantum resources
Bartosz Regula, Ludovico Lami
We propose an approach to the study of quantum resource manipulation based on the basic observation that quantum channels which preserve certain sets of states are contractive with…
Classical shadow tomography for continuous variables quantum systems
Simon Becker, Nilanjana Datta, Ludovico Lami +1
In this article we develop a continuous variable (CV) shadow tomography scheme with wide ranging applications in quantum optics. Our work is motivated by the increasing experimenta…
Postselected quantum hypothesis testing
Bartosz Regula, Ludovico Lami, Mark M. Wilde
We study a variant of quantum hypothesis testing wherein an additional 'inconclusive' measurement outcome is added, allowing one to abstain from attempting to discriminate the hypo…
Overcoming entropic limitations on asymptotic state transformations through probabilistic protocols
Bartosz Regula, Ludovico Lami, Mark M. Wilde
The quantum relative entropy is known to play a key role in determining the asymptotic convertibility of quantum states in general resource-theoretic settings, often constituting t…
Exact solution for the quantum and private capacities of bosonic dephasing channels
Ludovico Lami, Mark M. Wilde
The capacities of noisy quantum channels capture the ultimate rates of information transmission across quantum communication lines, and the quantum capacity plays a key role in det…
On a gap in the proof of the generalised quantum Stein's lemma and its consequences for the reversibility of quantum resources
Mario Berta, Fernando G. S. L. Brandão, Gilad Gour +4
We show that the proof of the generalised quantum Stein's lemma [Brandão & Plenio, Commun. Math. Phys. 295, 791 (2010)] is not correct due to a gap in the argument leading to Lemma…
Quantum Optical Communication in the presence of strong attenuation noise
Francesco Anna Mele, Ludovico Lami, Vittorio Giovannetti
Is quantum communication possible over an optical fibre with transmissivity ? The answer is well known to be negative if the environment with which the incoming signal…
Restoring quantum communication efficiency over high loss optical fibres
Francesco Anna Mele, Ludovico Lami, Vittorio Giovannetti
In the absence of quantum repeaters, quantum communication proved to be nearly impossible across optical fibres longer than due to the drop of transmissivity…
A Post-Quantum Associative Memory
Ludovico Lami, Daniel Goldwater, Gerardo Adesso
Associative memories are devices storing information that can be fully retrieved given partial disclosure of it. We examine a toy model of associative memory and the ultimate limit…
Computable lower bounds on the entanglement cost of quantum channels
Ludovico Lami, Bartosz Regula
A class of lower bounds for the entanglement cost of any quantum state was recently introduced in [arXiv:2111.02438] in the form of entanglement monotones known as the tempered rob…
