Control of Stochastic Quantum Dynamics by Differentiable Programming
Frank Schäfer, Pavel Sekatski, Martin Koppenhöfer +2
Control of the stochastic dynamics of a quantum system is indispensable in fields such as quantum information processing and metrology. However, there is no general ready-made appr…
Optimal distributed sensing in noisy environments
Pavel Sekatski, Sabine Wölk, Wolfgang Dür
We consider distributed sensing of non-local quantities. We introduce quantum enhanced protocols to directly measure any (scalar) field with a specific spatial dependence by placin…
All macroscopic quantum states are fragile and hard to prepare
Andrea López-Incera, Pavel Sekatski, Wolfgang Dür
We study the effect of local decoherence on arbitrary quantum states. Adapting techniques developed in quantum metrology, we show that the action of generic local noise processes -…
Macroscopic superpositions require tremendous measurement devices
M. Skotiniotis, W. Dür, P. Sekatski
We consider fundamental limits on the detectable size of macroscopic quantum superpositions. We argue that a full quantum mechanical treatment of system plus measurement device is…
