Single-photon detectors (SPDs) are ubiquitous in many protocols for quantum imaging, sensing, and communications. Many of these protocols critically depend on the precise knowledge of their detection efficiency. A method for the calibration...

We implement a DC voltage reference by measuring Stark shifts of cesium Rydberg atoms in a vapor cell. Cesium atoms are excited from the ground state to the 15s state via a degenerate two-photon transition that provides a narrow, Doppler fr...

Because noise is inherent to all measurements, optical communication requires error identification and correction to protect and recover user data. Yet, error correction, routinely used in classical receivers, has not been applied to receiv...
Estimation of the number of single-photon emitters for multiple fluorophores with the same spectral signature [0.03%]

Fluorescence microscopy is of vital importance for understanding biological function. However, most fluorescence experiments are only qualitative inasmuch as the absolute number of fluorescent particles can often not be determined. Addition...

Communication is an integral part of human life. Today, optical pulses are the preferred information carriers for long-distance communication. The exponential growth in data leads to a "capacity crunch" in the underlying physical systems. O...
