[QuEST](https://quest.qtechtheory.org/) is developed by Simon Benjamin’s Quantum Technology Theory Group (qtechtheory) and the e-Research center (oerc) at the University of Oxford. Development is currently led by Tyson Jones.

A full-state strong simulator, representing pure quantum states by state vectors, and mixed states by density matrices, with precise complex amplitudes in the Z-basis, The Quantum Exact Simulation Toolkit is a high-performance quantum computer simulator toolkit, state vectors and density matrices. QuEST uses multithreading, GPU acceleration and distribution to run lightning first on laptops, desktops and networked supercomputers. QuEST just works; it is stand-alone, requires no installation, and is trivial to compile and get running.
