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 …

In the past decade, semiconducting qubits have made great strides in overcoming
decoherence, improving the prospects for scalability and have become one of the leading …

Future quantum computers capable of solving relevant problems will require a large number
of qubits that can be operated reliably. However, the requirements of having a large qubit …

The global quantum internet will require long-lived, telecommunications-band photon–
