Scientists Achieve Major Quantum Computing Breakthrough
A team of scientists has made a significant breakthrough in quantum computing. They successfully demonstrated spin readout in a 22-nm integrated circuit, marking a major step towards practical quantum processors.
The team achieved high visibility (over 90%) in spin readout and observed millisecond spin relaxation times, proving the reproducibility of their method. Notably, they converted spin information into a measurable electrical signal using a radio-frequency single-electron transistor and on-chip cryogenic electronics for device control.
The research team achieved this feat using fully depleted silicon-on-insulator technology, directly reading spins within a standard 22-nanometer integrated circuit in a single shot. This breakthrough paves the way for more scalable quantum systems by integrating classical addressing electronics with quantum components on a single chip.
While the specific company or research group behind this achievement remains unclear, their work represents a significant stride towards building complex quantum processors. By integrating control electronics and spin qubits onto a single manufacturing platform, they bring us closer to practical, large-scale quantum computing.
