About QubiStack
We build the software that makes quantum tractable.
QubiStack is a quantum computing software company. Founded in June 2025 by HPC and quantum researchers from Seoul National University, we build high-performance quantum circuit simulation for researchers.
What we do
Quantum hardware is years from practical use. Until then, classical simulation is how researchers actually develop algorithms. We build the high-performance simulator and the software stack that bridges that gap, combining digital and quantum computing.
