Certified measurement and control of an entanglement-breaking index on programmable hardware
Eran Kopel
The entanglement-breaking index of a quantum channel, the number of self-compositions after which the channel destroys all entanglement with any reference, has to our knowledge nev…

Certified coherent, informative, and non-entanglement-breaking fixed points of future-referential quantum feedback
Eran Kopel
We study quantum processes in which information extracted from a forward simulation is returned as input to an earlier internal time of the simulated dynamics: externally the proto…
