New paper from researchers at the Institute for Quantum Computing (IQC) shows new method that could help connect quantum devices
Institute for Quantum Computing (IQC) researchers at the University of Waterloo have demonstrated a new technique to help connect quantum devices over long distances, a critical component to realizing a quantum internet.
Using a photon source called a nanowire quantum dot, IQC researchers have demonstrated a new method that fine tunes the source’s frequency to better enable quantum information sharing. By freezing a thin layer of nitrogen gas on the nanowire surface, they managed to tune the quantum dot photons to the frequency of specific atoms called caesium.
Ours is a new technique that tunes photons from the quantum dot so precisely that they can match specific spectral features of the atoms — similar to hitting exact musical notes when tuning a guitar string.
