Stationary optomechanical entanglement between a mechanical oscillator and its measurement apparatus
C. Gut, K. Winkler, J. Hoelscher-Obermaier +9
We provide an argument to infer stationary entanglement between light and a mechanical oscillator based on continuous measurement of light only. We propose an experimentally realiz…
Experimentally exploring compressed sensing quantum tomography
A. Steffens, C. Riofrio, W. McCutcheon +6
In the light of the progress in quantum technologies, the task of verifying the correct functioning of processes and obtaining accurate tomographic information about quantum states…
An efficient quantum algorithm for spectral estimation
A. Steffens, P. Rebentrost, I. Marvian +2
We develop an efficient quantum implementation of an important signal processing algorithm for line spectral estimation: the matrix pencil method, which determines the frequencies…
Quantum singular value decomposition of non-sparse low-rank matrices
Patrick Rebentrost, Adrian Steffens, Seth Lloyd
In this work, we present a method to exponentiate non-sparse indefinite low-rank matrices on a quantum computer. Given an operation for accessing the elements of the matrix, our me…
Continuous matrix product state tomography of quantum transport experiments
G. Haack, A. Steffens, J. Eisert +1
In recent years, a close connection between the description of open quantum systems, the input-output formalism of quantum optics, and continuous matrix product states in quantum f…
