## Go from unbearable friction to boundless achievement with Hybrid Control.
There’s far too much friction in our Quantum R&D – and we’re all feeling it. Slow progress, long runtimes, too high latencies. This happens when control is disjointed: the quantum control units are poorly integrated with the needed classical compute, and the quantum operations run on a completely different thread from the classical ones.
And the friction is only getting worse as qubits improve and scale.
Hybrid Control harmonizes quantum and classical operations, eliminating friction and optimizing performance across software and hardware so builders can iterate at speed, resolve setbacks, and bring their visionary ideas to life.
 “Quantum Machines’ OPX played a key role in our roadmap. It enabled us to get the best control electronics out there \[FPGA\] without having to learn how to program them. QM provides a very scalable, very easy to use and very powerful hardware, which allows us to focus on the quantum science.”
 Théau Peronnin
CEO and Co-Founder Alice & Bob
 “Diraq is delighted to partner with Quantum Machines, and credits their OPX control system, with its real-time capabilities, as instrumental in achieving the results outlined in our research. The ease of programming sequences in QUA significantly streamlined the experimental process.”
