Renormalization in the Theory of Open Quantum Systems via the Self-Consistency Condition
Marek Winczewski, Robert Alicki
We investigate the topic of renormalization in the theory of weakly interacting open quantum systems. Our starting point is an open quantum system interacting with a single heat ba…
Fundamental limitations on the device-independent quantum conference key agreement
Karol Horodecki, Marek Winczewski, Siddhartha Das
We provide several general upper bounds on the rate of a key secure against a quantum adversary in the device-independent conference key agreement (DI-CKA) scenario. They include b…
Intermediate Times Dilemma for Open Quantum System: Filtered Approximation to The Refined Weak Coupling Limit
Marek Winczewski, Antonio Mandarino, Gerardo Suarez +2
The famous Davies-GKSL secular Markovian master equation is tremendously successful in approximating the evolution of open quantum systems in terms of just a few parameters. Howeve…
