2025: The Year of Quantum Computing

Fault-tolerant quantum may still be years away, but the investable opportunity is here today

From cybersecurity and networking to middleware and sensing, quantum is already creating real companies and real returns.

As a partner at Notion Capital and CEO of Arqit, I split my time between the venture side and the sharp end of quantum cybersecurity. I want to answer a few questions in this piece:

- Do we have to wait for a fully error-corrected, cryptography-breaking quantum computer before meaningful companies can be built?

- Does the UK and Europe have an advantage?

- And where, specifically, is Notion Capital looking to invest as this new technology emerges?
