The spin degree of freedom of an electron or a nucleus is one of the most basic properties of
nature and functions as an excellent qubit, as it provides a natural two-level system that is …

We review the recent progress in theory and experiments with lateral triple quantum dots
with controlled electron numbers down to one electron in each dot. The theory covers …

Spin qubits involving individual spins in single quantum dots or coupled spins in double
quantum dots have emerged as potential building blocks for quantum information …

We demonstrate a reconfigurable quantum dot gate architecture that incorporates two
interchangeable transport channels. One channel is used to form quantum dots, and the …

The goal of this article is to review the progress of three-electron spin qubits from their
inception to the state of the art. We direct the main focus towards the exchange-only qubit …

The phenomenon of super-radiance (Dicke effect, coherent spontaneous radiation by a gas
of atoms coupled through a common radiation field) is well known in quantum optics. This …

We experimentally investigate the charge (isospin) frustration induced by a geometrical
symmetry in a triangular triple quantum dot. We observe the ground-state charge …

Spin qubits based on interacting spins in double quantum dots have been demonstrated
successfully,. Readout of the qubit state involves a conversion of spin to charge information …

The transport of quantum information between different nodes of a quantum device is among
the challenging functionalities of a quantum processor. In the context of spin qubits, this …

The development of the first generation of commercial quantum computers is based on
superconductive qubits and trapped ions respectively. Other technologies such as …
