Researchers and engineers from QuTech in the Netherlands and from Intel Corp., jointly designed and tested a chip to control qubits that can operate at extremely low temperatures, and opens the door to solving the "wiring bottleneck," an important step toward a scalable quantum computer. Their results are published in the scientific journal Nature.
Each basic unit of a quantum computer, a qubit, is typically addressed individually by a single wire. "This stands in the way of a scalable quantum computer, since millions of qubits would...
