Scaling Up!

In order to reach commercial viability, at scale, we need to increase the qubit count, while keeping the best performance and connectivity. Here we present our scale-up architecture, relying on a dynamically reconfigurable multi-core QPUs, and multi-qubit gates. This unique approach yields a powerful, effective, highly connected, and small footprint QPUs, and supporting extreme scalability.

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.
