QuTech researchers are the first to build a single-hole qubit


One of the key challenges in building the much coveted and very powerful quantum computer is the building of qubits (quantum bits) that can be scaled to large numbers. Using only standard semiconductor manufacturing techniques, researchers from QuTech have now demonstrated that a single hole, trapped in a germanium quantum dot, can be effectively used as a qubit. Their work was published in Nature Communications on July 10. read more
