Entanglement, non-Markovianity, and causal non-separability
Simon Milz, Felix A. Pollock, Thao P. Le +2
Quantum mechanics, in principle, allows for processes with indefinite causal order. However, most of these causal anomalies have not yet been detected experimentally. We show that…
Test one to test many: a unified approach to quantum benchmarks
Ge Bai, Giulio Chiribella
Quantum benchmarks are routinely used to validate the experimental demonstration of quantum information protocols. Many relevant protocols, however, involve an infinite set of inpu…
Enhanced communication with the assistance of indefinite causal order
Daniel Ebler, Sina Salek, Giulio Chiribella
In quantum Shannon theory, the way information is encoded and decoded takes advantage of the laws of quantum mechanics, while the way communication channels are interlinked is assu…
Units of rotational information
Yuxiang Yang, Giulio Chiribella, Qinheping Hu
Entanglement in angular momentum degrees of freedom is a precious resource for quantum metrology and control. Here we study the conversions of this resource, focusing on Bell pairs…
Benchmark for the quantum-enhanced control of reversible dynamics
Yin Mo, Giulio Chiribella
Controlling quantum systems is crucial for quantum computation and a variety of new quantum technologies. The control is typically achieved by breaking down the target dynamics int…
Quantum Stopwatch: How To Store Time in a Quantum Memory
Yuxiang Yang, Giulio Chiribella, Masahito Hayashi
Quantum mechanics imposes a fundamental tradeoff between the accuracy of time measurements and the size of the systems used as clocks. When the measurements of different time inter…
