Temporal information processing on a 4,500-qubit quantum annealer
Antonio Sannia, Roberto Menta, Pratik Sathe +7
Quantum machine learning could uncover statistical structure beyond the reach of classical models, but this requires quantum models large and expressive enough to be useful and che…
Optimized QUBO formulation methods for quantum computing
Dario De Santis, Salvatore Tirone, Stefano Marmi +1
Several combinatorial optimization problems can be solved with NISQ devices once that a corresponding quadratic unconstrained binary optimization (QUBO) form is derived. The aim of…
Physicality of evolution and statistical contractivity are equivalent notions of maps
Matteo Scandi, Paolo Abiuso, Dario De Santis +1
Statistical quantifiers are generically required to contract under physical evolutions, following the intuition that information should be lost under noisy transformations. This pr…
Quantum Fisher Information and its dynamical nature
Matteo Scandi, Paolo Abiuso, Jacopo Surace +1
The importance of the quantum Fisher information metric is testified by the number of applications that this has in very different fields, ranging from hypothesis testing to metrol…
Pure non-Markovian evolutions
Dario De Santis
Non-Markovian dynamics are characterized by information backflows, where the evolving open quantum system retrieves part of the information previously lost in the environment. Henc…
Ancillary Gaussian modes activate the potential to witness non-Markovianity
Dario De Santis, Donato Farina, Mohammad Mehboudi +1
We study how the number of employed modes impacts the ability to witness non-Markovian evolutions via correlation backflows in continuous-variable quantum dynamics. We first prove…
Characterizing (non-)Markovianity through Fisher Information
Paolo Abiuso, Matteo Scandi, Dario De Santis +1
A non-isolated physical system typically loses information to its environment, and when such loss is irreversible the evolution is said to be Markovian. Non-Markovian effects are s…
Equivalence between non-Markovian dynamics and correlation backflows
Dario De Santis, Markus Johansson
The information encoded into an open quantum system that evolves under a Markovian dynamics is always monotonically non-increasing. Nonetheless, for a given quantifier of the infor…
A correlation measure detecting almost all non-Markovian evolutions
Dario De Santis, Markus Johansson, Bogna Bylicka +2
We investigate the ability of correlation measures to witness non-Markovian open quantum system dynamics. It is shown that the mutual information and any entanglement measure betwe…
