Physicists at the University of Sydney have achieved a breakthrough in quantum computing by creating a universal logic gate inside a single atom. Using a powerful error-correcting system known as the Gottesman-Kitaev-Preskill (GKP) code — often called the “Rosetta Stone” of quantum computing — they managed to entangle vibrations of a trapped ion. This achievement […]



Summary

University of Sydney physicists have achieved a quantum computing milestone by building a universal logic gate within a single atom. Employing the advanced Gottesman-Kitaev-Preskill (GKP) error-correcting code, they successfully entangled the vibrational states of a trapped ion. This breakthrough offers enhanced precision and stability compared to previous methods, paving the way for more robust and scalable quantum computers. The GKP code’s effectiveness in minimizing errors is crucial for realizing fault-tolerant quantum computation, making this a significant step towards practical applications.
