Intel and QuTech deliver first industrially manufactured qubit

Engineers from Intel and scientists from QuTech have delivered the first qubit made in the very same industrial manufacturing facilities that mass-produce conventional computer chips. This advancement has been a long-standing goal due to its promise of scalability. The breakthrough is a crucial step towards scaling to the thousands of qubits that are needed for practical quantum computation.

The type of quantum information that makes this qubit is the electron spin. The electron is trapped inside a “box”, given by a potential well in an energy landscape, called a quantum dot. The energy landscape is produced by a combination of material properties (similar layouts to a conventional transistor: silicon–silicon oxide interface) and electric fields. In this way it is possible to isolate and address a single electron in the quantum dot and have full control over its spin.

The paper has been published in Nature Electronics.
