Abstract

We experimentally measured higher order normalized correlation functions (NCF) of pulsed light with a time-multiplexing detector. We demonstrate excellent performance of our device by verifying unity valued NCF up to the eighth order for coherent light and factorial dependence of the NCF for pseudothermal light. We applied our measurement technique to a type-II parametric down-conversion source to investigate mutual two-mode correlation properties and ascertain nonclassicality.

Benchmarking the Future-Proofedness of Photonic Quantum Systems

Johannes Tiedau, Melanie Engelkemeier, Benjamin Brecht +2 more

Targeting at the realization of scalable photonic quantum technologies, the generation of many photons, their propagating in large optical networks, and a subsequent detection and analysis of sophisticated quantum correlations is essential for the understanding of macroscopic quantum systems. In this experimental contribution, we explore the joint operation of all mentioned ingredients. We benchmark our time-multiplexing framework that includes a high-performance source of multi-photon states and a large multiplexing network, together with unique detectors with high photon-number resolution, readily available for distributing quantum light and measuring complex quantum correlations. Using an adaptive approach that employs flexible time bins, rather than static ones, we successfully verify high-order nonclassical correlations of many photons distributed over many modes. By exploiting the symmetry of our system and using powerful analysis tools, we can analyze correlations that would be inaccessible by classical means otherwise. In particular, we produce in the order of ten photons and distribute them over sixty-four modes. Nonclassicality is verified with correlation functions up to the one hundred and twenty-eighth order and statistical significances of up to twenty standard deviations.

Time-multiplexed measurements of nonclassical light at telecom wavelengths

Georg Harder, Christine Silberhorn, Jaroslav Řeháček +4 more

We report the experimental reconstruction of the statistical properties of an ultrafast pulsed type II parametric down-conversion source in a periodically poled potassium titanyl phosphate waveguide at telecom wavelengths, with almost perfect photon-number correlations. We use a photon-number-resolving time-multiplexed detector based on a fiber-optical setup and a pair of avalanche photodiodes. By resorting to a germane data-pattern tomography, we assess the properties of the nonclassical light states with unprecedented precision.

Uncovering Quantum Correlations with Time-Multiplexed Click Detection

Jan Sperling, Martin Bohmann, W. Vogel +4 more

We report on the implementation of a time-multiplexed click detection scheme to probe quantum correlations between different spatial optical modes. We demonstrate that such measurement setups can uncover nonclassical correlations in multimode light fields even if the single mode reductions are purely classical. The nonclassical character of correlated photon pairs, generated by a parametric down-conversion, is immediately measurable employing the theory of click counting instead of low-intensity approximations with photoelectric detection models. The analysis is based on second- and higher-order moments, which are directly retrieved from the measured click statistics, for relatively high mean photon numbers. No data postprocessing is required to demonstrate the effects of interest with high significance, despite low efficiencies and experimental imperfections. Our approach shows that such novel detection schemes are a reliable and robust way to characterize quantum-correlated light fields for practical applications in quantum communications.

Study of the Glauber correlation functions in a pulsed mode

I. N. Agafonov, T. Sh. Iskhakov, Maria V. Chekhova

A method for measuring the Glauber correlation functions in a pulsed mode is proposed. The effect of the detector dead time on the shape of a measured correlation function is analyzed. The second-order intensity correlation functions for coherent and quasi-thermal radiation, as well as for biphoton light emitted during spontaneous parametric down-conversion, are measured in a nanosecond pulsed mode.
