The Who’s Who of Quantum: A Directory of 40+ Quantum Companies from Around the World

This article introduces you to over 40 quantum companies from around the world.
This article introduces you to over 40 quantum companies from around the world.

With the quantum ecosystem ever-growing, it can be hard to determine who are the key players in this industry. In order to help understand the leaders and stakeholders of quantum, we at The Quantum Insider will guide you on a world tour to meet 40+ quantum companies, research facilities, and groups that provides a “who’s who” of the quantum world.

This is an ever-changing list, with new players emerging and the development of major partnerships. We know this isn’t an exhaustive list by any means – data from The Quantum Insider Intelligence platform captures over five hundred companies in the quantum tech value chain, and details on their operations – but it gives you a flavour of a cross-section of key quantum organizations and areas that they focus on.

This list will also reveal which locations around the world are current quantum “hotspots,” showing how this industry needs collaboration on a worldwide scale in order to succeed. Many of these companies have multiple locations around the world, making them global leaders, so we’ve tried to identify just one location so they’re not placed in multiple categories.

If you want to learn more, we’ve compiled the most comprehensive list of the top quantum computing companies available!
