Extending classical processors to support future large scale quantum accelerators

Extensive research in material science together with outstanding engineering efforts allowed quantum technology to be significantly improved hence enabling continuing scaling of quantum circuit size. In around 10 years, quantum annealing circuits have reached 103 qubits and trailing by several years, universal quantum circuits now demonstrate similar trends. From the current trends we can expect that quantum computers will reach thousands of qubits in the next 5--10 years.
