Connecting distant silicon qubits for scaling up quantum computers

https://phys.org/news/2023-03-distant-silicon-qubits-scaling-quantum.html

"scale up from hundred to millions of qubits... two-qubit logic gate between physically distant silicon spin qubits... scaling up quantum computing based on silicon quantum dots... coherent spin shuttling connect 2 qbits enabling single spin qubits move across arra quantum dots without affecting their phase coherence... pushing electrons through qubit array by applying voltage... increase the separation to about a micrometer or so... will make the method more practical for future use"
