Quantum machine learning with glow for episodic tasks and decision games
Jens Clausen, Hans J. Briegel
We consider a general class of models, where a reinforcement learning (RL) agent learns from cyclic interactions with an external environment via classical signals. Perceptual inpu…
Time-optimal bath-induced unitaries by Zermelo navigation: speed limit and non-Markovian quantum computation
Jens Clausen
The solution of the quantum Zermelo navigation problem is applied to the non-Markovian open system dynamics of a set of quantum systems interacting with a common environment. We co…
Multiple re-encounter approach to radical pair reactions and the role of nonlinear master equations
Jens Clausen, Gian Giacomo Guerreschi, Markus Tiersch +1
We formulate a multiple-encounter model of the radical pair mechanism that is based on a random coupling of the radical pair to a minimal model environment. These occasional pulse-…
Approaches to Measuring Entanglement in Chemical Magnetometers
M. Tiersch, G. G. Guerreschi, J. Clausen +1
Chemical magnetometers are radical pair systems such as solutions of pyrene and N,N-dimethylaniline (Py-DMA) that show magnetic field effects in their spin dynamics and their fluor…
Task-dependent control of open quantum systems
Jens Clausen, Guy Bensky, Gershon Kurizki
We develop a general optimization strategy for performing a chosen unitary or non-unitary task on an open quantum system. The goal is to design a controlled time-dependent system H…
Dynamical control of quantum state transfer within hybrid open systems
B. M. Escher, G. Bensky, J. Clausen +2
We analyze quantum state-transfer optimization within hybrid open systems, from a "noisy" (write-in) qubit to its "quiet" counterpart (storage qubit). Intriguing interplay is revea…
