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 race to build a fault-tolerant superconducting quantum computer
From IEEE Spectrum: Amazon, Google, and IBM are all pursuing different strategies to reduce error rates. Q-NEXT collaborator Oskar Painter of Caltech and team find they can 'make cat qubits that are highly resistant to bit flip, where a qubit flips from one state to another, one of two main sources of error a superconducting qubit can have.'
