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 [...]

Brandão study presents a new quantum algorithm related to semidefinite problems

A new Caltech study, by Fernando Brandão and collaborators, demonstates that quantum computing could be applied to speed up solutions to "semidefinite programs" a class of optimization problems."One of the goals of quantum computing is to speed up computations to levels that far exceed what classical computers can do," says Fernando Brandão, the Bren Professor [...]
