Qutrit Randomized Benchmarking on a Transmon Quantum Processor

ORAL

Abstract

Qutrits present an alternative to qubits for implementing quantum computation by using three-, rather than two-level systems, and have proven useful to explore connections between high-energy physics and quantum information science. Leveraging this extra level can also be used to extend the reach of current quantum hardware. In this talk, we present a scheme to generalize Randomized Benchmarking (RB) protocols to qutrits, and we experimentally implement them on a 5-transmon processor. More specifically, we measure the performance of our single-qutrit gate with RB and interleaved RB. We then use cycle benchmarking to assess the performance of our CSUM gate - the generalization of the CNOT for qutrits.
