Silicon Quantum Computer

Value creation through calculations that cannot be solved by classical methods

  1. Now
    • Development shift from hybrid with classical computers (NISQ) to quantum error correction quantum computers
  3. 2030
    • Demonstration of small-scale quantum error correction quantum computers
  5. 2050

We develop quantum computing using quantum phenomena observed at the electronic level scale, and accelerate the development of new materials and operate large-scale social systems by computing complex and large-scale problems that cannot be solved by conventional classical computing.
