An integrated control and measurement system for driving, manipulating, and reading qubits, designed according to Quantum Machines’ Hybrid Control approach

Hybrid Control

At the OPX+’s core, the Hybrid Processing Unit (HPU) seamlessly integrates quantum operations (pulses and measurements) with ultra-fast classical processing and control flow. This innovative design minimizes overhead, reduces latency, and enables the execution of complex quantum algorithms that were previously impossible.

Ultra Fast

OPX+ reduces conditional feedback latency to 224 ns and supports fully parametric feedback: readout, classical calculations, and parameter updates in 272 ns. With no central controller architecture, a cluster of OPX+ units provides ultra-fast feedback between any of the qubits. Advanced sequences like 5,000-depth Randomized Benchmarking run in minutes, with no uploading or compilation time.

 

Hybrid Development Platform

The OPX+ hybrid development platform unifies quantum and classical programming. At its core is QUA, a powerful pulse-level language that enables developers to effortlessly implement complex quantum algorithms while seamlessly integrating classical processing. The platform also includes automated calibration via QUAlibrate and a vast library of control applications.

Always Up to Date

HPU logic (hardware) upgrades keep your system aligned with quantum innovation, allowing the introduction of new and important features to the processor logic, in addition to regular software updates. Additionally, you gain access to a library of pre-built programs for most characterization experiments, including contributions from leading research groups.
