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 …

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 …

Identifying and ameliorating dominant sources of decoherence are important steps in
understanding and improving quantum systems. Here, we show that the free induction …

Heisenberg exchange coupling between neighboring electron spins in semiconductor

We consider a pair of quantum dot-based spin qubits that interact via microwave photons in
a superconducting cavity and that are also parametrically driven by separate external …

Quantum computers can potentially provide an unprecedented speed-up with respect to
traditional computers. However, a significant increase in the number of quantum bits (qubits) …

Semiconductor quantum dots are promising hosts for qubits to build a quantum processor. In
the last twenty years, intensive researches have been carried out and diverse kinds of qubits …

We theoretically model the spin-orbit interaction in silicon quantum dot devices, relevant for
