NCSA's Mission in Quantum Computing: A Path towards Dependable Quantum Cyberinfrastructure and Productivity

Strategic Insights -

Quantum computing, the theoretical possibility of using quantum mechanics to solve quantum mechanical problems faster than with classical computers, has come a long way since its inception in the 1980s. From experiments in academic laboratories to products that are either sold as deployable units or can be accessed via the cloud, quantum hardware has evolved significantly. However, despite the significant progress, the quantum computing market is still in its early stages, and major challenges need to be overcome before it can reach its full potential.

Key Takeaways:

  • Quantum computing takes the extraordinary relationship between physics and information to new heights, with potential applications in solving hard problems that can have major impacts for the economy and some of the grand challenges of our time.
  • The current state of the art suggests that the classes of problems solvable by classical computers are the same as the classes of problems solved by quantum computers, even if the latter have more physical resources than the former.
  • The development of high-level programming languages for quantum computers is still in its infancy, with current languages requiring very low-level specifications, which is both painstaking and inefficient.
  • NCSA's mission in quantum computing is to contribute to the advancement of quantum computing platforms toward dependable quantum cyberinfrastructure, influence the quantum software ecosystem, and create high-level quantum programming languages.
  • The National Center for Supercomputing Applications (NCSA) has crafted a quantum computing vision that is scientifically informed and tempered by the expertise of colleagues in the Illinois Quantum Information Science and Technology Center.
  • Recent work at NCSA includes contributing to the advancement of quantum computing platforms, digital twins for superconducting quantum devices, HPC-QPU integration, and creating new high-level quantum programming languages.
  • The workshop on Broadly Accessible Quantum Computing at PEARC24 in July provided participants with a comprehensive understanding of the current status and prospects of quantum computing and its applications.

Statistics:

  • The quantum computing market is expected to reach $1.5 billion by 2026 and potential economic value in the trillions of dollars by 2035.
  • Quantum computing devices currently operate in temperature and vacuum regimes outside usual values found anywhere in the universe, indicating the delicacy of quantum states.
  • Fault tolerance remains distant on the horizon, with recent advances pointing in that direction.
  • The scalability of entanglement, a key quantum resource, is still an open question.
  • The current state of the art suggests a small number of problems with large speedups, others with more modest speedups, and many where there is no advantage.
