Who Has The Best Quantum Computer?

This podcast episode discusses the current state and future of quantum computing, focusing on the companies involved, their qubit counts, and the challenges in comparing different quantum systems. The speakers emphasize that qubit count alone is not a reliable metric and introduce the concept of quantum volume as a benchmarking scheme. They highlight Quantinium's System Model H12 as having the highest published quantum volume. Looking ahead, they outline the steps needed to create useful quantum computers, including error correction and the creation of logical qubits, and share predictions from companies like IBM, Google, D-Wave, and others regarding their progress in the field, with a common goal of achieving around 1,000 qubits by 2024-2025. The speakers advocate for companies to provide more comprehensive information, such as meeting DiVincenzo's criteria and publishing quantum volume results, to enable better analysis of their claims.
