Jellybean Quantum Dots in Silicon for Qubit Coupling and On‐Chip Quantum Chemistry (Adv. Mater. 19/2023)

Jellybean Quantum Dots Highly elliptical, elongated, quantum dots—so-called jellybean dots—can be used for qubit–qubit coupling over short-to-intermediate distances and alleviate crowding in scaled-up processors, as described by Zeheng Wang, Arne Laucht, co-workers article number 2208557. The cover illustration shows an artist's impression of two spin qubits silicon metal–oxide–semiconductor dots that are coupled through such a coupler.
