A new method of fabricating quantum circuits has been developed, allowing the largest “gate-defined” quantum circuit to date. The technique, known as the “Chessboard-like Method” was developed by a team of physicists from the University of Science and Technology of China and published in Nature Communications.

The Chessboard-like Method is a novel approach to fabricating quantum circuits that utilizes a lattice structure, similar to a chessboard, to precisely define the areas of each gate. By utilizing this approach, the team was able to create a circuit containing 8,824 gates, the largest quantum circuit of its kind. With this new technique, the team is hopeful that they can continue to expand the number of gates in future experiments.
