Quantum 6, 654 (2022). https://doi.org/10.22331/q-2022-02-16-654 Quantum systems generally exhibit different kinds of correlations. In order to compare them on equal footing, one uses the so-called distance-based approach where different types of correlations are captured by […]
Quantum 6, 653 (2022). https://doi.org/10.22331/q-2022-02-16-653 A multiple access channel describes a situation in which multiple senders are trying to forward messages to a single receiver using some physical medium. In this paper we consider scenarios […]
Topology of Rigetti’s 80 Qubit Processor. Credit: Rigetti Computing Rigetti has taken the next step with their 80 qubit Aspen-M-1 processor by making it commercial available on both Rigetti’s Quantum Cloud Service (QCS) and also […]
Phonons are collective atomic vibrations, or quasiparticles, that act as the main heat carriers in a crystal lattice. Under certain circumstances, their properties can be modified by electric fields or light. But until now, nobody […]

Mathematicians often work together when they’re searching for insight into a hard problem. It’s a kind of freewheeling collaborative process that seems to require a uniquely human touch. But in two new results, the role […]
