30‑m Cryogenic Microwave Link Enables Loophole‑Free Bell Test
Are you curious about the insights we gained when building our 30-m-long cryogenic microwave-frequency quantum link which we used to do a loophole free Bell test with superconducting qubits? This system also serves as a role model for how to interconnect devices in a large-scale modular superconducting #quantum #computer. In the new paper A Modular Cryogenic Link for Microwave Quantum Communication Over Distances of Tens of Meters out on @arxiv today we describe some of our learnings from constructing the system.

The work was done at the Quantum Device Lab (https://t.co/cF4jsoFdYJ) of the Department of Physics (@ETH_physics) and the @ETHQuantumCntr of @ETH_en Zurich by Josua D. Schär, @simonstorz , Paul Magnard (now at Isentroniq), @PhilippKurpiers (now at Rohde & Schwarz), Janis Lütolf, Melvin Gehrig, @BesseJC , Anatoly Kulikov, and @AndreasAtETH with support from the European Research Council (ERC), and @ETH Zürich.
Worried Airlines Will Lose My Special Luggage Again
Special luggage. Where am I going and what for? Also will Swiss and Air Canada manage to loose my gear again? https://t.co/m6kebMBAcD
Lattice Surgery Achieved on Superconducting Repetition Codes
Need to perform surgery on your logical #qubits? Here is how to do it with #superconducting #circuits. With lattice surgery you can entangle logical qubits, which is a step required for realizing two-qubit gates between logical qubits. This is particularly useful...
