Purpose-built by quantum experimentalists and engineers for quantum physics, OPX+ has unmatched capabilities. It is agile and flexible, allowing easy programming and the fastest runtime of most complex quantum programs.

Processor-Based
Controller

At the heart of OPX+ is a multi-core Pulse Processing Unit (PPU). It combines classical calculation with quantum control pulses and control flow in real time. Instead of playing pulse sequences from memory, the PPU generates and manipulates them on-the-fly, reducing uploading times and memory usage to near zero.

Unique Real-Time
Capabilities

OPX+ reduces conditional feedback to 220 ns and can do 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.

 

Unboxing to Randomized
Benchmarks
in Two Days

Randomized benchmarking with a depth > 5,000 gates and thousands of repetitions runs in minutes, with no uploading or compilation time. Easy programming and out-of-the-box workflow libraries deliver the fastest time to results.

Always Up to Date

Processor logic (hardware) upgrades keep your system in line with quantum innovation, allowing the introduction of new and important features down to processor logic, on top of regular software updates.
