Fast convergence of propagation algorithms for open quantum systems

We establish general conditions for the rapid convergence of propagation algorithms for computing expectation values of local observables in quantum many-body systems, covering both spin and fermionic systems. Our results apply to evolutions that are sufficiently contractive, providing a general mechanism by which cont...

Randomness can be certified in energy-constrained semi-device-independent scenarios

This work addresses the open question affirmatively: certified randomness generation is theoretically possible in the energy-constrained SDI framework even in the presence of a fully quantum adversary by constructing semidefinite programming relaxations of the guessing probability.
