Qulacs is a high-speed simulator of quantum circuits for quantum computational research.

By calling the library written in C ++ via the Python interface, it makes high speed calculation and convenience compatible.

For algorithm development of quantum computers, a simulation with classical computers without errors is crucial. QunaSys conducts research and development using Qulacs.

This system is developed by Fujii group at Kyoto University and we are conducting maintenance and developing new functions.

New participants to our Qulacs Slack community, R&D using Qulacs, new function proposals and development at GitHub are always welcome.
