Ytterbium: Rare Earth; Make QC Networks Commonplace?

French and Swiss research teams have tested varying amplitude and direction of magnetic fields around atoms of the rare earth element, Ytterbium. The teams have found a “magic point” which permits a thousand-fold increase in coherence. Such a discovery helps move along the concept of building quantum computing networks with the aid of quantum repeaters. High-coherence (longevity) is needed to ensure signals sent are alive for the entire distance to the receiver, or the next repeater as the case may be.

Quantum-Secure Encryption in Your Smartphone

A team affiliated with the University of Bristol has devised a tiny (1 mm square) random number generator which generates numbers at 2.8 Gbps speeds using silicon photonics technology found in semiconductor fabrication methods. This rate of photon generation and its inherent randomness coupled with a “very low” power consumption give this QRNG potential to secure encryption at the mobile-device level.
