13 OPTIMIZED DRIVER SCHEDULING REDUCTION IN SCHEDULING TIME 80% Canada’s largest Western-based provider of food and health products is moving multiple quantum hybrid applications into production. The first, an e-commerce driver delivery scheduling application, is now in production to create schedules that serve over 100 stores. This application has trimmed what was an 80- hour task to just 15 hours each week, an 80% time savings. The company will soon bring another quantum-hybrid application into production that optimizes in-store resource scheduling in stores across Canada. COPYRIGHT © D-WAVE

14 AUTOMATED TOUR ROUTING TASK REDUCED FROM 12 HOURS TO LESS THAN ONE HOUR Identifying optimal routes for promotional tours is critical to ensuring all client requirements and federal regulations are considered. The Interpublic Group worked with D-Wave to identify routes that reduce the costs of producing and running these tours. D-Wave’s technology was able to solve the given problem in less than an hour and is well designed to allow for an easy transition to a full production-quality application. COPYRIGHT © D-WAVE

15% INCREASE IN RESOURCE UTILIZATION ENHANCED RADAR SCHEDULING Davidson, a technology services company that provides innovative engineering, technical and management solutions for the Department of Defense, aerospace and commercial customers, has been working with D-Wave on several quantum- hybrid applications to advance national defense efforts. Most recently we’ve built a radar scheduling application that efficiently manages the time-limited resources of a phased- array radar system, enabling scheduling of communication with moving objects. We observed enhanced resource utilization in all our test cases. On average, we achieved a 15% increase in utilization across all problem scenarios and time limits, with the highest improvement reaching an impressive 42%. COPYRIGHT © D-WAVE 15

OPTIMIZED CUSTOMER REWARDS PROGRAM Satispay is the leading Italian fintech unicorn focused on revolutionizing mobile payments. Together we’ve built a quantum-hybrid application that optimizes customer rewards initiatives. Using D-Wave’s constrained quadratic model hybrid solver, the application showed an improvement of 50% in customer rewards programs for the same amount of budget. A testament to its potential business value, Satispay plans to transition the quantum-hybrid application into production, with internal teams expected to use it weekly.
