OTCQB: QUBT 5 Why Quantum Computing?

OTCQB: QUBT Why We are Here: The Classical Computing Dilemma Quality • As data grows, experts have found ways to compress problems mathematically. • However, this creates tradeoff in the quality of result. Speed • Problems increasingly have hundreds of thousands of variables to factor in. • As data and variables increase, longer times are required to solve problems. Diversity • Binary nature of classical limits to single answer. • Leaves other needed solutions, like process optimization, off the table Quantum Computing Promises to Solve These Challenges Increasing amounts of data requires fast & better insights for business decisions. yet classical computer processing limits are challenged by the explosion of data . 6

OTCQB: QUBT Quantum Momentum in the Market 7 • The Next Big Wave: This is not just a new technology – Emergence of quantum computing has catalyzed a new revolution in technology. • Major Investment: Industry giants like IBM, Microsoft, Google, Amazon and Honeywell are investing huge resources, as well as the U.S., China, and EMEA. • Growing Demand: While it could still be years before quantum hardware shows real business advantages operating independently from classical computers, businesses are demanding results today. • First Mover Advantage: Just as software and apps were the keys to the PC and smartphone revolutions, the same holds true for quantum computing: the first movers will be the biggest winners. • QCI is the Only Public Pure Quantum Software Play: Only publicly - traded company 100% focused on leading the transition from classical to quantum computing with software that avoids significant expense and time required for quantum programming.

OTCQB: QUBT Example QC Application Retail Supply Chain Optimization 23 Ecommerce shift complicates everything. Covid accelerated that shift. • Shopping baskets. From single basket with lots of items to many baskets with few items. • Supply Chain availability. Shifting demand and Covid lockdowns/delays mean raw materials and product availability is a dynamic and ever - changing target. • Consumer expectations. Customers expect unlimited product selection and availability at the lowest price. The emerging differentiator is becoming delivery time. • As many as 96% of customers consider faster delivery synonymous with same - day delivery. • In a study by McKinsey & Company, the primary aspect of customer service mentioned by customers?
