Qutess

At Qutess Lab, we have developed a polarization-based EPS at a wavelength suitable for free space and also at telecom wavelengths. It is a compact instrument that can produce > 1 MHz photon pairs using the spontaneous parametric down-conversion (SPDC) process. We can provide customized entangled photon sources.
