Macroscopic quantum states: measures, fragility and implementations
Florian Fröwis, Pavel Sekatski, Wolfgang Dür +2
Large-scale quantum effects have always played an important role in the foundations of quantum theory. With recent experimental progress and the aspiration for quantum enhanced app…
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…
Adaptive quantum metrology under general Markovian noise
R. Demkowicz-Dobrzanski, J. Czajkowski, P. Sekatski
We consider a general model of unitary parameter estimation in presence of Markovian noise, where the parameter to be estimated is associated with the Hamiltonian part of the dynam…
General measure for macroscopic quantum states beyond "dead and alive"
Pavel Sekatski, Benjamin Yadin, Marc-Olivier Renou +3
We consider the characterization of quantum superposition states beyond the pattern "dead and alive". We propose a measure that is applicable to superpositions of multiple macrosco…
