Summary

In this talk, Mike Piech, VP of Business Development at Rigetti Computing, provides an overview of superconducting quantum computing. He introduces Rigetti as a company, highlighting its history, team, and achievements. He explains the three main application areas for quantum computing: chemistry simulation, optimization, and machine learning. He then discusses the key parameters of quantum computers: qubit count, error rate, coherence time, and gate speed. He explains the physics behind superconducting qubits, focusing on the Josephson junction and the LC circuit, and describes the physical setup, including dilution refrigerators and microwave control. He presents Rigetti’s roadmap, including their 84-qubit system and plans for over 100 qubits by end of 2025. He emphasizes the importance of their in-house fabrication facility and the software stack. He also discusses the market for quantum computers, noting that current customers are mainly government labs and universities, and mentions the availability of a 9-qubit system for under $2 million. The talk concludes with a Q&A session where he elaborates on sales strategies and the different QPU offerings.
