Reconstruction of Markovian dynamics from untimed data
Jochen Rau
I develop a theoretical framework for inferring nonequilibrium equations of motion from incomplete experimental data. I focus on genuinely irreversible, Markovian processes, for wh…
Appearance of Gibbs states in quantum-state tomography
Jochen Rau
I investigate the extent to which the description of quantum systems by Gibbs states can be justified purely on the basis of tomographic data, without recourse to theoretical conce…
Direct estimation of decoherence rates
Vladimír Bužek, Peter Rapcan, Jochen Rau +1
The decoherence rate is a nonlinear channel parameter that describes quantitatively the decay of the off-diagonal elements of a density operator in the decoherence basis. We addres…
Assessing thermalization and estimating the Hamiltonian with output data only
Jochen Rau
I consider the generic situation where a finite number of identical test systems in varying (possibly unknown) initial states are subjected independently to the same unknown proces…
Reconstructing the relaxation dynamics induced by an unknown heat bath
Jochen Rau
In quantum state tomography, one potential source of error is uncontrolled contact of the system with a heat bath whose detailed properties are not known, and whose impact on the s…
On the metric structure of space-time
Jochen Rau
I present an analysis of the physical assumptions needed to obtain the metric structure of space-time. For this purpose I combine the axiomatic approach pioneered by Robb with idea…
