Maximal intrinsic randomness of noisy quantum measurements
Fionnuala Curran, Morteza Moradi, Gabriel Senno +2
Quantum physics exhibits an intrinsic and private form of randomness with no classical counterpart. Any setup for quantum randomness generation involves measurements acting on quan…
Beyond Ground States: Physics-Inspired Optimization of Excited States of Classical Hamiltonians
Erik Altelarrea-Ferré, Júlia Barberà-Rodríguez, David Jansen +1
We introduce excited local quantum annealing (ExcLQA), a classical, physics-inspired algorithm that extends local quantum annealing (LQA) to identify excited states of classical Is…
Mapping Phase Diagrams of Quantum Spin Systems through Semidefinite-Programming Relaxations
David Jansen, Donato Farina, Luke Mortimer +5
Identifying quantum phase transitions poses a significant challenge in condensed matter physics, as this requires methods that both provide accurate results and scale well with sys…
Quantum Key Distribution over Complex Networks
Luca Mariani, Raja Yehia, Carlos Pascual-García +4
There exist several initiatives worldwide to deploy quantum key distribution (QKD) over existing fibre networks and achieve quantum-safe security at large scales. To understand the…
Myths around quantum computation before full fault tolerance: What no-go theorems rule out and what they don't
Zoltán Zimborás, Bálint Koczor, Zoë Holmes +19
In this perspective article, we revisit and critically evaluate prevailing viewpoints on the capabilities and limitations of near-term quantum computing and its potential transitio…
Continuous-variable quantum communication
Vladyslav C. Usenko, Antonio Acín, Romain Alléaume +8
Tremendous progress in experimental quantum optics in recent decades has enabled the advent of quantum technologies, one of which is quantum communication. Aimed at novel methods f…
All pure multipartite entangled states of qubits can be self-tested up to complex conjugation
Maria Balanzó-Juandó, Andrea Coladangelo, Remigiusz Augusiak +2
Self-testing refers to the certification of quantum states and measurements based entirely on the correlations exhibited by measurements on separate subsystems. In the bipartite ca…
Harnessing quantum back-action for time-series processing
Giacomo Franceschetto, Marcin Płodzień, Maciej Lewenstein +2
Quantum measurements affect the state of the observed systems via back-action. While projective measurements extract maximal classical information, they drastically alter the syste…
Certifying steady-state properties of open quantum systems
Luke Mortimer, Donato Farina, Grazia Di Bello +4
Estimating the steady-state properties of open many-body quantum systems is a fundamental challenge in quantum science and technologies. In this work, we present a scalable approac…
Long-distance device-independent quantum key distribution using single-photon entanglement
Anna Steffinlongo, Mariana Navarro, Marina Cenni +3
Device-independent quantum key distribution (DIQKD) provides the strongest form of quantum security, as it allows two honest users to establish secure communication channels even w…
