Physicists at the University of Oxford achieved the most accurate control of a qubit, with an error rate of just 0.000015%.
This breakthrough sets a new global benchmark for quantum computing accuracy, reducing the need for extra qubits and making quantum computers smaller, faster, and more efficient.
The team used a single calcium ion as a qubit and microwave signals for control, allowing the experiment to be conducted at room temperature without special magnetic shielding.
While single-qubit operations are now highly accurate, improving two-qubit operations will be crucial for creating fully functional, fault-tolerant quantum computers.
