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