What to know

  • Researchers at Chalmers University developed a method to perform quantum operations 1,000+ times faster by consolidating thousands of control cycles into one.
  • The speed increase directly improves reliability by reducing quantum information's exposure to environmental disturbances (electrical noise, cosmic radiation, overheating) that cause errors.
  • The breakthrough uses bosonic quantum codes that store information in microwave fields within superconducting circuits rather than individual qubits, providing stronger error protection.
  • The advance moves quantum computing closer to fault-tolerance, a necessary step before these machines can transform drug discovery, energy technology, cryptography, and artificial intelligence.

“The longer a quantum operation takes, the greater the risk of computational errors.”

    Speed reduction directly improves quantum computing reliability

    The breakthrough demonstrates that in quantum computing, speed is tightly coupled with reliability—fewer cycles mean less exposure to environmental disturbances like electrical noise and cosmic radiation that cause errors to accumulate, making the operations both faster and more efficient.

    “The fundamental building blocks of quantum computers, known as qubits, are so sensitive that even the smallest disturbance can cause the quantum state to deviate from the target, resulting in the loss of information.”

    Chalmers researchers publish method for 1,000x faster quantum operations

    Lei Du and Tangyou Huang at Chalmers University of Technology in Sweden published a theoretical study in Physical Review Letters describing a method to perform advanced quantum operations on bosonic states more than 1,000 times faster by completing them in a single driving cycle rather than thousands of repeated cycles.

    “Our method shows that a diverse range of quantum operations on bosonic states can be completed within a single driving cycle, rather than the several thousand cycles that have been required previously.”
