The Quantum exact simulation toolkit serves as a robust simulator for quantum circuits, state-vectors, and density matrices. QuEST harnesses the power of multithreading, GPU acceleration, and distributed computing to execute tasks rapidly on devices ranging from laptops to networked supercomputers. It operates seamlessly without requiring installation and can be easily compiled for immediate use. With no setup needed, users can download, compile, and launch QuEST in just seconds. Additionally, it has no external dependencies, allowing for native compilation on various operating systems including Windows, Linux, and MacOS. No matter if you are using a laptop, desktop, supercomputer, or even a microcontroller in the cloud, getting QuEST up and running typically requires only a handful of terminal commands. This accessibility makes QuEST a preferred choice for those delving into quantum simulations.
