Will we get a full-scale quantum computer that changes everything?

It's a question I've oscillated on during my career.

So I've been a quantum physicist for 30 or so years.

If you'd asked me very early on, I would've been very pessimistic, then I got more pessimistic [laughs] and more pessimistic, and then things started changing for me.

When a technology comes along that promises to improve people's day-to-day lives, we as a society are willing to take a stab in the dark, and that's Warwick, our gadget guy's, reflection as well.

If we do build quantum computers, they will be possibly the most sophisticated, complicated machine that humanity has ever made, and they will fundamentally change how we can do computation, so that's, that's a massive benefit for science and for humanity, and so I think it's worth the risk.

I think we need to be investing and trying to make it happen.
