Silicon-based atomic processors achieve stable interconnection of 11 qubits.

According to the latest issue of the journal Nature, a research team from the Australian startup company SQC has built a new type of quantum processor based on silicon materials and phosphorus atoms, achieving connectivity of 11 quantum bits in experiments while maintaining high operational fidelity. This is one of the largest silicon-based atomic quantum processors of its kind to date and is considered an important advancement in the field of quantum computing.
