Transfer of quantum-enhanced information through a many-body system
Piotr Wysocki, Marcin Płodzień, Jan Chwedeńczuk
Forthcoming quantum devices will require high-fidelity information transfer across a many-body system. We formulate the criterion for lossless signal propagation and show that a si…

Limits to velocity of signal propagation in many-body systems: a quantum-information perspective
Piotr Wysocki, Jan Chwedeńczuk
The Lieb-Robinson bound (LRB) states that the range and strength of interactions between the constituents of a complex many-body system impose upper limits to how fast the signal c…
