Unbounded separation between definite and indefinite causal order in finite-dimensional quantum metrology
Yanglin Hu, Zi-Shen Li, Giulio Chiribella +1
Indefinite causal order is known to offer enhancements in quantum metrology, notably including an unbounded advantage in the measurement of a geometric phase of a harmonic oscillat…
Higher-order quantum thermodynamics: equilibrium and causal structure
Simon Milz, Kyrylo Simonov, Zoltán Zimborás +3
Quantum thermodynamics is traditionally formulated as a theory of equilibrium states and state transformations. Recent advances in higher-order quantum transformations, which descr…
Virtual quantum neural networks
Benchi Zhao, Xuanqiang Zhao, Yinan Li +2
Quantum neural networks are a prominent model of quantum machine learning. Their training consists in the minimization of a given loss function over a parametrized family of quantu…
Learning to Reconstruct Wigner Functions in Phase Space
Xinyu Tang, Yi-hsin Lin, Yan Zhu +5
Wigner function learning is a central tool for characterizing continuous variable quantum systems. A fundamental challenge in this setting is to infer a continuous phase-space func…
Quantum learning with a single-atom sensor
Yin Mo, Emilio Bagan, Giulio Chiribella
The ability to gather information and to act upon it is at the core of every learning agent. But what is the impact of quantum mechanics on an agent's ability to sense external inp…
On-Chip Quantum Randomness Amplification
Lang Li, Yutian Wu, Giulio Chiribella +1
Randomness amplification, the task of extracting uniform private bits from biased seeds that may be partly known by a malicious third party, is of central importance in cryptograph…
