Researchers from Harvard, MIT and QuEra have achieved a significant breakthrough in quantum computing by successfully implementing high-fidelity parallel entangling gates on a neutral-atom quantum computer. This advancement, detailed in a recent study published in Nature, allows for the operation of two-qubit controlled phase gates with a remarkable 99.5% fidelity on up to 60 atoms simultaneously. This surpasses the threshold required for practical quantum error correction, paving the way for more robust and scalable quantum computing systems. The technology utilizes a sophisticated method of optimal control along with improvements in atom cooling and excitation, setting a new standard in the field of quantum information processing.
