Experimental quantum key distribution certified by Bell's theorem
D. P. Nadlinger, P. Drmota, B. C. Nichol +12
Cryptographic key exchange protocols traditionally rely on computational conjectures such as the hardness of prime factorisation to provide security against eavesdropping attacks.…
Optimal nonequilibrium thermometry in Markovian environments
Pavel Sekatski, Martí Perarnau-Llobet
What is the minimum time required to take a temperature? In this paper, we solve this question for a large class of processes where temperature is inferred by measuring a probe (th…
Approximate decoherence free subspaces for distributed sensing
Arne Hamann, Pavel Sekatski, Wolfgang Dür
We consider the sensing of scalar valued fields with specific spatial dependence using a network of sensors, e.g. multiple atoms located at different positions within a trap. We sh…
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…
