Quantum computation features known examples of hardware acceleration for certain
problems, but is challenging to realize because of its susceptibility to small errors from noise …

Semiconductor moiré superlattices provide a versatile platform to engineer quantum solids
composed of artificial atoms on moiré sites. Previous studies have mostly focused on the …

Semiconductor quantum dots (QDs) in planar germanium (Ge) heterostructures have
emerged as front-runners for future hole-based quantum processors. Here, we present …

Large-scale arrays of quantum-dot spin qubits in Si/SiGe quantum wells require large or
tunable energy splittings of the valley states associated with degenerate conduction band …

Silicon-germanium heterostructures have successfully hosted quantum dot qubits, but the
intrinsic near-degeneracy of the two lowest valley states poses an obstacle to high-fidelity …

The simplest possible structural transition that an electronic system can undergo is Wigner
crystallization. The aim of this short review is to discuss the main aspects of three recent …

The small size and excellent integrability of silicon metal–oxide–semiconductor (SiMOS)
quantum dot spin qubits make them an attractive system for mass‐manufacturable, scaled …

Electrons confined in silicon quantum dots exhibit orbital, spin, and valley degrees of
freedom. The valley degree of freedom originates from the bulk band structure of silicon …

Liquid He-4 is free from magnetic defects, making it an ideal substrate for electrons with long-
lived spin states. Such states can serve as qubit states. Here we consider the spin states of …

Multielectron semiconductor quantum dots (QDs) provide a novel platform to study the
Coulomb interaction-driven, spatially localized electron states of Wigner molecules (WMs) …
