Quantum Machines Announces General Availability of Its Pulse Processing Unit (PPU) for Real Time ...

The Quantum Machines Pulse Processing Unit (PPU), codenamed Hadamard, consists of an FPGA based unit with 18 processor cores that includes multiple waveform generators, digitizers, and processing units. It works with the rest of the OPX+ which includes analog to digital and digital to analog converters as well as a communications backplane which will provide all the needed control interfaces to the qubits. A key feature of the PPU is that it includes flexible, real-time control capabilities to support such things as error correction, mid-circuit measurements and If/Else and Case statements for conditional execution in real time. These capabilities allow the unit to alter the operation during the execution based upon conditions inside the circuit. Many other control implementations do not currently have this capability and will just provide a series of control pulses that were pre-planned ahead of time. Quantum Machines indicated that this capability has been able to speed up circuit execution by up to 5000 times in some situations. The PPU can be programmed with QUA, Quantum Machines Python-based quantum pulse-level programming language.
