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…
Sequential Semi-Device-Independent Quantum Randomness Certification
Carles Roch I Carceller, Hanwool Lee, Jonatan Bohr Brask +2
Quantum measurements under realistic conditions reveal only partial information about a system. Yet, by performing sequential measurements on the same system, additional informatio…
Privacy in continuous-variable distributed quantum sensing
A. de Oliveira Junior, Anton L. Andersen, Benjamin Lundgren Larsen +5
Can a distributed network of quantum sensors estimate a global parameter while protecting every locally encoded value? We answer this question affirmatively by introducing and anal…
Long-Distance Device-Independent Conference Key Agreement
Makoto Ishihara, Anders J. E. Bjerrum, Wojciech Roga +3
Device-independent quantum key distribution (DI-QKD) enables two remote parties to share an information-theoretically secure key without any assumptions on the inner workings of th…
Benchmarks for quantum communication via gravity
Kristian Toccacelo, Ulrik Lund Andersen, Jonatan Bohr Brask
We establish limitations and bounds on the transmission of quantum states between gravitationally interacting mechanical oscillators under different models of gravity. This provide…
A friendly guide to exorcising Maxwell's demon
A. de Oliveira Junior, Jonatan Bohr Brask, Rafael Chaves
The birth, life, and death of Maxwell's demon provoked a profound discussion about the interplay between thermodynamics, computation, and information. Even after its exorcism, the…
