Turning a million-qubit quantum computing dream into reality
From The Next Platform: Earlier this year, Intel announced that it had successfully fabricated more than 10,000 arrays, each with three to 55 quantum dots, on a 300-millimeter wafer with a yield higher than 95%. Q-NEXT collaborator James Clarke, director of quantum hardware at Intel, says the feat was made possible thanks to the fact that Intel, unlike most other companies pursuing quantum, runs its own fabs, which the company also used to manufacture the control logic needed that allows such a high density of qubits.

The quest for an ideal quantum bit
From Argonne National Laboratory: Q-NEXT collaborator David Schuster and team create a new qubit platform formed by freezing neon gas into a solid at very low temperatures, spraying electrons from a light bulb’s filament onto the solid, and trapping a single electron there. This system shows great promise to be developed into ideal building blocks for future quantum computers. Read More
