Quantum 6, 655 (2022). https://doi.org/10.22331/q-2022-02-16-655 Information-theoretic ideas have provided numerous insights in the progress of fundamental physics, especially in our pursuit of quantum gravity. In particular, the holographic entanglement entropy is a very useful tool […]
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 […]
Quantum 6, 652 (2022). https://doi.org/10.22331/q-2022-02-15-652 The $textit{stabilizer rank}$ of a quantum state $psi$ is the minimal $r$ such that $left| psi right rangle = sum_{j=1}^r c_j left|varphi_j rightrangle$ for $c_j in mathbb{C}$ and stabilizer states […]
Quantum 6, 651 (2022). https://doi.org/10.22331/q-2022-02-15-651 Steering criteria are conditions whose violation excludes the possibility of describing the observed measurement statistics with local hidden state (LHS) models. When the available data do not allow to exclude […]
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 […]
Credit Where it’s Due As readers will already know who have been reading our content over the last few years, The Quantum Insider likes to cover startups making a difference within our industry. We think it’s […]
