Energy cost of entanglement extraction in complex quantum systems
Cedric Beny, Christopher T. Chubb, Terry Farrelly +1
What is the energy cost of extracting entanglement from complex quantum systems? In other words, given a state of a quantum system, how much energy does it cost to extract m EPR pa…

Quantum deconvolution
Cédric Bény
We propose a method for stably removing noise from measurements of a quantum many-body system. The question is cast to a linear inverse problem by using a quantum Fischer informati…
