Real-time randomized compilation of quantum algorithms

Recent experiments have indicated the effectiveness of Pauli Frame Randomization (PFR) as a noise shaping technique. Not only does PFR tailor general noise into Pauli-stochastic noise, it also decouples qubits from their noise environment increasing system Markovianity. Presently, the randomization process requires extensive pre-compilation of pulse sequences. Here, we demonstrate an in hardware implementation of PFR on the BBN Arbitrary Pulse Sequencer II that generates randomized sequences in real-time. We first implement randomized benchmarking without pre-computing pulse sequences before using this capability to randomize a Gate Set Tomography experiment on a superconducting quantum processor.
