Parametric oscillators are a driven harmonic oscillator that based on nonlinear process in a resonant cavity, which are widely used in various areas of physics. In the past, parametric oscillators ...

Since it was first demonstrated in the 1960s, spontaneous parametric down-conversion (SPDC) has been at the center of many quantum optics experiments that test the fundamental laws of physics in ...

A University of Ottawa team has developed a new way to protect free-space quantum key distribution (QKD) from atmospheric turbulence, one of the main causes of distortion and errors when sending ...
