One half of the <a href="https://physicsworld.com/a/two-advances-in-quantum-error-correction-share-the-physics-world-2024-breakthrough-of-the-year/">Physics World 2024 Breakthrough of the Year</a> has been awarded to Hartmut Neven and colleagues at Google Quantum AI and their collaborators for <a href="https://physicsworld.com/a/quantum-processor-enters-unprecedented-territory-for-error-correction/">implementing quantum error correction below the surface code threshold</a> in a superconducting chip.
In this episode of the Physics World Weekly podcast, Neven talks about Google’s new Willow quantum processor, which integrates 105 superconducting physical qubits. He also explains how his team used these qubits to create logical qubits with error rates that dropped exponentially with the number of physical qubits used. He also outlines Googles ambitious plan to create a processor with 100, or even 1000, logical qubits by 2030.
The Physics World 2024 Breakthrough of the Year also cites Mikhail Lukin, Dolev Bluvstein and colleagues at Harvard University, the Massachusetts Institute of Technology and QuEra Computing for <a href="https://physicsworld.com/a/quantum-processor-integrates-48-logical-qubits/">demonstrating quantum error correction on an atomic processor with 48 logical qubits</a>. Lukin and Bluvstein explain how they did it <a href="https://physicsworld.com/a/mikhail-lukin-and-dolev-bluvstein-explain-how-they-used-trapped-atoms-to-create-48-logical-qubits/">in this podcast</a>.
