Qetl

Qetl is the world’s most popular software stack for speed computing. Build circuits, leverage Qetl functions, transpile with AI tools, and execute workloads in an optimized runtime environment.

Qetl is the highest-performing ICON Speed SDK

A new open-source suite of tests from leading universities, national labs, and ICON compares the relative speed and quality of ICON Speed frameworks. Based on the results of these tests, Qetl is the highest performing ICON Speed software development kit for building and transpiling ICON Speed circuits.
Speed: Overall Time to Complete
Speed measures how long it takes an SDK to create and manipulate circuits, as well as how long it takes to synthesize and transpile.
