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.
