Post by The Hilbert Space Post

The July 16th edition of the Hilbert Space Post covers quantum simulations of quantum magnets by Google, ion trap with more than 100 ions, benchmark of quantum optimization and production of quantum-dots spin qubits with semiconductor manufacturing processes. Here is today selection: 1️⃣ Precision quantum simulation of magnon spectra and interactions 🔗 https://lnkd.in/gmMJNWSZ 👨👩 Trond Andersen, Nikita Astrakhantsev, Jeronimo Martinez, William Morong, Dario Rossi et al. (Google) 🔬 A new work by Google uses a 97-qubit superconducting quantum simulator to emulate a 2D quantum magnet, create and manipulate magnons, measure their spectra and lifetimes, and directly observe their interactions. 2️⃣ A versatile laser-machined rf trap for arrays of 100+ ions 🔗 https://lnkd.in/gUemB8Kc 👨👩 Frank Schroer, Ilyoung Jung, Thomas W. Burkle, Jack Lyons, Joseph Van Vlack, Joseph Ezuma and Philip Richerme 🔬 A new paper presents a scalable and highly controllable ion-trap platform capable of arranging over 100 ions into different one- and two-dimensional structures. 3️⃣ A Reality Check on Quantum Optimisation: Evidence from an Industrial Case Study 🔗 https://lnkd.in/gDtS9SsF 👨👩 Hila Safi, Dr. Karen Wintersperger, Oliver von Sicard, Christoph Niedermeier and Wolfgang Mauerer 🔬 A new work benchmarks quantum, quantum-inspired, and classical approaches for industrial job-shop scheduling. The paper shows that achieving practical benefits requires co-designing the mathematical formulation with the hardware constraints. 4️⃣ SiMOS quantum-dot spin qubits enabled by extreme-ultraviolet lithography 🔗 https://lnkd.in/gfDW8dDU 👨👩 Thomas Van Caekenberghe, Paul S., Bart Raes, Sofie Beyne, Clément Godfrin et al. 🔬 Extreme-ultraviolet semiconductor lithography can fabricate highly uniform silicon spin qubits while achieving near-fault-tolerant gate fidelities, establishing a path toward scalable quantum processors compatible with advanced industrial semiconductor manufacturing. That’s it for the daily selection. If you enjoyed it, please consider giving us a like or reposting to support our content. Thanks!
