Quantum Leap: Breakthroughs Bring Us Closer to Revolutionary Computing
Google DeepMind has applied artificial intelligence to quantum error correction, developing a model called AlphaQubit. This AI-driven decoder leverages the same transformer neural network technology behind tools like ChatGPT and AlphaFold.
Quantum computers, long heralded as the future of computational power, are edging closer to practical application. Recent breakthroughs by leading companies, including IBM, Microsoft, and Google DeepMind, indicate significant progress in overcoming longstanding challenges such as scalability and error correction. These advancements hint at transformative impacts across fields like materials science, chemistry, and beyond.
IBM showcased its latest development by successfully linking two of its Eagle quantum processing units, each containing 127 qubits. This innovative connection enabled the system to perform calculations requiring 142 qubits—exceeding the capacity of either individual chip. This was achieved using a method involving entangling qubits and “teleporting” one to another chip, mediated by classical computers. Blake Johnson of IBM describes this approach as strategic for scaling quantum systems by breaking problems down. Although this marks just the beginning, experts like Scott Aaronson from the University of Texas at Austin see it as foundational for building larger superconducting quantum systems.
Error correction, another major hurdle, is also seeing notable progress. Microsoft and Atom Computing recently reported achieving entanglement of 24 logical qubits, marking a record for reducing computational errors found on qubit systems. Their system utilized ultracold ytterbium atoms and achieved error rates four times lower than conventional methods. Krysta Svore from Microsoft emphasized the importance of these logical qubits for breakthroughs in quantum applications, aiming for 50 logical qubits, with aspirations for 100—an important threshold for addressing complex scientific issues.
Meanwhile, Google DeepMind has utilized AI for quantum error correction through its model AlphaQubit. This AI decoder interprets data from error-detecting qubits, achieving 6% fewer errors compared to earlier algorithms. Johannes Bausch of Google DeepMind notes this improvement, though modest, has scalability advantages over other methods and is key for future, larger-scale quantum systems.
Experts agree these advancements collectively indicate rapid technological maturation. Aaronson recognizes the growing synergy between classical and quantum computing, especially as machine learning tools like AlphaQubit boost the efficiency and accuracy of quantum error correction.
