  • Quantum advantage is not the end goal but a milestone in quantum computing, requiring quantum and classical methods to outperform purely classical ones.
  • IBM announced new tools and research at the Quantum Developer Conference (QDC) to help scale quantum advantage, including new processors and software advances.
  • Three categories of quantum advantage experiments were presented: observable estimation, variational algorithms, and problems with efficient classical verification.
  • IBM introduced the Quantum Advantage Tracker, an open, community-led tool to monitor and evaluate quantum advantage candidates against classical methods.
  • New hardware includes the 120-qubit IBM Quantum Nighthawk, designed for scalability and performance, and the improved IBM Quantum Heron with lower error rates.
  • Qiskit SDK v2.2 was released, offering significant performance improvements and new features like box annotations and dynamic circuits for better error mitigation.
  • IBM is advancing towards fault-tolerant quantum computing with new fabrication processes and the IBM Quantum Loon processor, testing key components for qLDPC codes.
  • A real-time error correction decoder, RelayBP, was implemented on an AMD FPGA, achieving fast decoding times critical for error correction.
