Loved by our community

Undoubtedly the best tool I have seen. The interactiveness helps to visualize the problems for better understanding, even for someone with a physics background and prior knowledge on the topic.

Rafiul Nakib

Quantum Computing Research Intern

This course is amazing. Orders of magnitude easier to follow than any other quantum computing learning resource I've come across. Really looking forward to the skills that are coming soon.

Kevin Carr

Senior Software Engineer

Black Opal is the best educational tool to learn about quantum computing in a visual way that makes it easier to understand the main topics like superposition, qubits, entanglement, and noise.

Jose Finocchio

Business Development in Education

Amazing for anyone who doesn't have a PhD or a Master's degree like me. It's easy to understand with bite sized exercises and mini tests so you retain knowledge.

Hannaah S.

Physics Student

Black Opal is the best educational tool around quantum control and computation I've seen so far. I love the graphical interfaces as well.

John K.

Engineer

Black Opal is amazing, I've upgraded to a Pro subscription. Explaining complex topics in simple terms - that's brilliant.

Ivan Verkalets

CTO and Founder

Loved by our community

Black Opal helped me to understand quantum computing to a degree that I feel will allow me to progress in academia and career opportunities. I intend to expand my learning towards the professional certificate.

Aravind Ratnam

Chief Strategy Officer

Absolutely loving the experience. I've got to say it's really really well done - the 'byte-sized' lessons, interactive visualizations, exercises - everything is perfect.
