When Symmetry Suppresses Magic
A. de Oliveira Junior, Jake Xuereb, Rafael A. Macêdo +2
Nonstabilizerness is a critical resource for quantum advantage, but evaluating it, especially for mixed states, requires superexponentially many samples in system size, making the…
Anomalous Local Heat Capacity and Bipartite Entanglement
Jake Xuereb, A. de Oliveira Junior
The heat capacity of a system quantifies how it energetically responds to changes in temperature at equilibrium. Whilst this quantity is positive and even additive for non-interact…
Randomness Certification and Trade-offs in the Prepare-and-Broadcast Scenario
Tailan S. Sarubi, Moisés Alves, Vinícius F. Alves +4
We investigate the prepare-and-broadcast scenario, a multipartite extension of dimension-constrained prepare-and-measure experiments in which a quantum system is distributed to mul…
The Prepare and Broadcast Scenario
Tailan S. Sarubi, Moisés Alves, Santiago Zamora +3
We introduce the dimension-restricted prepare and broadcast (PAB) scenario, which generalizes standard prepare-and-measure frameworks. Here, the system prepared by a sender undergo…
Trading athermality for nonstabiliserness
A. de Oliveira Junior, Rafael A. Macedo, Jakub Czartowski +2
Quantum advantage arises from quantum states that cannot be efficiently simulated on a classical computer. Such states are characterised by a property known as nonstabiliserness. I…
Semi-device-independent randomness certification on discretized continuous-variable platforms
Moisés Alves, Vitor L. Sena, Santiago Zamora +4
Randomness is fundamental for secure communication and information processing. While continuous-variable optical systems offer an attractive platform for this task, certifying genu…
Reconstructing thermal states using dimensionally limited probes : A Model for Limited Control & Memory in Quantum Thermodynamics
Jake Xuereb, A. de Oliveira Junior, Fabien Clivaz +2
Whilst the complexity of acquiring knowledge of a quantum state has been extensively studied in the fields of quantum tomography and quantum learning, a physical understanding of i…
