Quantum Computing Cloud.  Harvard’s John A. Paulson School of Engineering and Applied Sciences researchers have shifted the frequency of photons using microwaves.  Using a molecule-like photonic system built with lithium niobate on a chip, the team demonstrated that light’s frequency and phase could be controlled by programmable microwave signals.  Further, the team was able to show on-demand optical storage and retrieval using the photonic molecule.  The team’s goal is to “achieve a quantum link between microwave and optical photons.”  Such an achievement would realize a network of quantum computers connected with quantum-secure links – a quantum computing cloud.
