Final Reminder to Register for The D-Wave Analyst Day 2022

D-Wave Analyst Day 2022: Welcome to

Commercial Quantum Computing

Quantum computing can be complex, but building a commercial business around it shouldn’t be. Don’t miss joining D-Wave, the world’s only commercial quantum computing company, at our first Investor Analyst Day on Thursday, May 12^th. The event is virtual and will be hosted by D-Wave’s CEO, Alan Baratz, and CFO, John Markovich. At the event, we will showcase how our strategy of developing and building annealing quantum computers and making them available via our Quantum Computing as a Service (QCaaS) platform enables us to sell into the Global 2000: expanding practical quantum hybrid business applications and unlocking the approximately 25% of the total addressable market today. We will be hosting a customer and partner panel with live Q&A session. D-Wave’s customers are building quantum applications for a broad spectrum of industries and use cases such as logistics, portfolio optimization, drug discovery, materials sciences, scheduling, fault detection, traffic congestion, and supply chain management. During Analyst Day, we will frame the near- and longer-term opportunity for commercial quantum computing; provide an update on our progress, and host a Q&A session with D-Wave management. The virtual meeting will begin promptly at 10:00am and conclude at 12:00pm EDT.
