New work by Vidick and collaborators featured in Nature Communications

A new paper, Practical device-independent quantum cryptography via entropy accumulation by Rotem Arnon-Friedman, Frédéric Dupuis, Omar Fawzi, Renato Renner, Thomas Vidick is in the January 31 issue of Nature Communications. Conventional quantum cryptography is already well developed both in theory and experiments. This is not the case, however, for device-independent quantum cryptography, which is the [...]

New Hsieh review “Towards properties on demand in quantum materials”

Quantum materials are on the ascent. This term embodies a vast portfolio of compounds and phenomena where ramifications of quantum mechanics are demonstrably real. Quantum materials are in the vanguard of contemporary physics in part because these systems afford an exceptional venue to uncover the many roles of symmetry, topology, dimensionality and strong correlations in [...]
