Modular nanomagnet design for spin qubits confined in a linear chain
TL;DR: In this paper, the authors present a design aimed at driving spin qubits arranged in a linear chain and strongly confined in directions lateral to the chain, where individual magnets are U-shaped, such that the magnetic shape anisotropy orients the magnetization alternately toward and against the qubit chain.

TL;DR: Researchers demonstrate a highly coherent singlet-triplet hole spin qubit in germanium, achieving 99.68% gate fidelity and 1.9μs coherence time, with a tenfold increase to 20.3μs via resonant driving and frequency modulation, enabling universal control and efficient operations in semiconductor-based quantum processors.
