About us
We hold the key to making quantum technology useful and operate at the highest levels of the emerging quantum sector. Our products are already revolutionizing the way quantum technology is used; From educating the workforce on how quantum computing works with Black Opal, to the industry-first native integration of our performance-management software with IBM Quantum services in November 2023, we are building the global quantum sector and defining the quantum infrastructure software segment. But our work isn’t limited to quantum computing; we go everywhere that quantum goes. In July 2023 our work with Australian Defence delivering software-ruggedized quantum sensing for navigation without GPS was featured in the New York Times.
We base these world-leading commercial outcomes on a foundation of transformational research. We operate the industry’s largest team of experts in quantum control, and push the limits of human capability through our software, hardware, and technical publications in the world’s most prestigious scientific journals.
As a high-growth global quantum startup we’ve raised US $74M since 2017 from investors such as Airbus Ventures, Horizons Ventures, Main Sequence Ventures, Salesforce Ventures, Sierra Ventures, SquarePeg Capital, and others; this includes the world’s largest Series B for any quantum software company, announced in early 2023. Adding to the completion of our new global HQ in Sydney (Australia’s first fully dedicated, commercial quantum technology site), Los Angeles, and Berlin offices, we’ve also recently announced our expansion into the UK to continue to impact the development of quantum technology globally.
We’re led by our values: to be real, to be trusted, to be just, and to be revered. We’ve brought together an inspiring team of world-leading physicists, engineers, product and design specialists (to name a few!) to help us shape the future of quantum technology. And we’re looking for new team members who want to help us change the world.
