Emulation of quantum measurements with mixtures of coherent states
A. Mikhalychev, Y. S. Teo, H. Jeong +2
We propose a methodology to emulate quantum phenomena arising from any non-classical quantum state using only a finite set of mixtures of coherent states. This allows us to success…
Experimental requirements for entangled two-photon spectroscopy
Stefan Lerch, André Stefanov
Entangled two-photon spectroscopy is expected to provide advantages compared with classical protocols. It is achieved by coherently controlling the spectral properties of energy-en…
Self-calibrating Optical Low-Coherence Reflectometry with Energy-Time Entangled Photons for Absolute Distance Measurements
Manuel Unternährer, André Stefanov
Optical low-coherence reflectometry is capable of unambiguously measuring positions of stacked, partially reflective layers in a sample object. It relies on the low coherence of th…
Properties of upconverted entangled broadband light
Stefan Lerch, André Stefanov
We experimentally investigate the properties of light generated by the sequential processes of spontaneous parametric downconversion followed by upconversion. By interfering the up…
Preliminary investigation of a new state estimation technique using device-independent maximum likelihood estimation
Sacha Schwarz, Bruno Eckmann, Denis Rosset +1
In quantum state tomography, the estimated frequencies do not correspond directly to a physical quantum state, due to statistical fluctuations. Thus, one resorts to point estimator…
Super-Resolution Quantum Imaging at the Heisenberg Limit
Manuel Unternährer, Bänz Bessire, Leonardo Gasparini +2
Quantum imaging exploits the spatial correlations between photons to image object features with a higher resolution than a corresponding classical light source could achieve. Using…
