Physicists at the University of Oxford in the United Kingdom have attained a groundbreaking achievement in single-qubit control precision, achieving an error rate of just 0.000015%. This substantial reduction in error rates minimizes the dependence on error correction in quantum computing, paving the way for the development of smaller, faster, and more efficient quantum computers. Utilizing microwave signals, the research team manipulated the quantum state of calcium ions and conducted experiments at ambient temperature, significantly lowering the technical barriers. Nonetheless, to achieve fully fault-tolerant quantum computing, further advancements in reducing the error rates of two-qubit gates remain essential.
