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…
Efficient and operational quantifier of non-divisibility in terms of channel discrimination
Ranieri Nery, Nadja K. Bernardes, Daniel Cavalcanti +2
The understanding of open quantum systems is crucial for the development of quantum technologies. Of particular relevance is the characterisation of divisible quantum dynamics, see…
Unified Framework for Correlations in Terms of Local Quantum Observables
A. Acín, R. Augusiak, D. Cavalcanti +5
We provide a unified framework for nonsignalling quantum and classical multipartite correlations, allowing all to be written as the trace of some local (quantum) measurements multi…
Macroscopic bound entanglement in thermal graph states
D. Cavalcanti, L. Aolita, A. Ferraro +2
We address the presence of bound entanglement in strongly-interacting spin systems at thermal equilibrium. In particular, we consider thermal graph states composed of an arbitrary…
Almost all quantum states have non-classical correlations
A. Ferraro, L. Aolita, D. Cavalcanti +2
Quantum discord quantifies non-classical correlations in a quantum system including those not captured by entanglement. Thus, only states with zero discord exhibit strictly classic…
Scaling laws for the decay of multiqubit entanglement
L. Aolita, R. Chaves, D. Cavalcanti +2
We investigate the decay of entanglement of generalized N-particle Greenberger-Horne-Zeilinger (GHZ) states interacting with independent reservoirs. Scaling laws for the decay of e…
