Researchers at Chalmers University of Technology have developed a new method using Quantum Lattice Gates (QLGs) that accelerates bosonic quantum operations by up to 1,000 times. This breakthrough allows for faster and more robust quantum error correction by completing complex quantum operations within a single Floquet driving period, rather than thousands of repeated cycles, making it compatible with existing superconducting quantum circuits. The technique has achieved high-fidelity state preparation and logical gate operations, scaling linearly with Hilbert-space dimension.

Chalmers researchers developed a method that performs bosonic quantum operations in one driving cycle, making operations over 1,000x faster.

So far, quantum computers have been held back by their extreme sensitivity to errors and external disturbances. The longer a quantum operation takes, the greater the risk that…
