Scientists have set a new world record in quantum computing by achieving an error rate of 0.000015%, which is nearly an order of magnitude lower than the previous record. This breakthrough could lead to the development of smaller and faster quantum computers that are both practical and efficient.
The achievement comes after years of research and development, with scientists using a bespoke platform made up of “trapped ions” to create a quantum computer that relies on microwaves instead of photons as qubits. The setup allows for precise control over the ions, which were placed into a hyperfine “atomic clock” state.
The team’s progress was achieved by reducing the noise generated by the computer’s architecture and control methods to almost zero. This reduction in error significantly reduces the infrastructure required for error correction, opening up new possibilities for future quantum computers.
According to Molly Smith, a graduate student in physics at the University of Oxford and co-lead author of the study, “By drastically reducing the chance of error, this work significantly reduces the infrastructure required for error correction, opening the way for future quantum computers to be smaller, faster, and more efficient.”
The achievement is still a far cry from solving all the fundamental challenges in practical, utility-scale quantum computing. However, it represents an important step forward and could pave the way for significant advancements in the field.
