Massively Improved Performance

Quantum computing performance is not only determined by hardware, but also by software and particularly the compilation of quantum algorithms (or circuits) to make the most out of the physical hardware configuration. In this paper we present efficient compilation based on our multi-qubit gates, to acheive significantly improved performance for a given hardware performance level, including various noise sources.

Quantum Volume Benchmark

Quantum Volume (QV)is a system level benchmark for quantum computing, which characterizes the effective number of qubits and circuit depth, in a 'worst case' scenario, by scrambling the connectivity and gate operations in several layers of the circuit, again and again. We show that our multi-qubit gates and all-to-all connectivity lead to an improvement of up to 25% in the log of the QV, for different noise models. This means that for a given hardware, our architecture and compiler provide a path to improved performance of orders of magnitude in this challenging benchmark, with an improved scaling.
