 I'd like you to start by imagining that this humble device was harnessing quantum mechanics to monitor your state of health and then to securely communicate with your doctor also harnessing quantum physics and that your doctor would then prescribe you a new drug that has been designed on a quantum simulator and that his diagnosis was informed by a quantum computer. Now that future and a whole lot more is potentially soon possible so as bizarre as quantum physics is it turns out to be the basis of some incredibly disruptive quantum technologies and what I'd really like to emphasize today is that these technologies are emerging from the research lab so at the University of Bristol we're working with a large range of organizations to develop these quantum technologies that will have profound impacts on all of our lives societies and economies. These will occur in four main areas the first is in security so probably all of you have wondered about how secure your mobile phone is when you log into your bank or you buy something online with it. Well working with our colleagues at Nokia we've developed a secure communication system that would allow your handheld device to communicate with your bank telemachine and the way that works is that you and your bank encode your information in single particles of light single photons and the laws of physics demand that if anyone extract some information from that transition that will disturb those single photons and you and your bank can detect that. The second area is in sensors which are becoming ubiquitous in transport environmental monitoring security and healthcare and it turns out that if you want those sensors to be as precise as they possibly can to make their measurements most precisely then you need to harness this bizarre properties of quantum physics. Already we have been able to measure the concentration of a blood protein using this bizarre state of entangled photons and that's a really key step to making this into a practical technology. And so the third area is in designing new materials new clean energy devices and new pharmaceuticals so probably many of you are aware that it takes of order a billion dollars in 10 years to bring just a single new drug to market and a big part of the reason for that is that it's impossible on a normal supercomputer to be able to simulate the molecules at the heart of that. So working with our colleagues at Harvard we've developed a new very efficient quantum algorithm for doing such a simulation and we've been able to simulate the helium hydride molecule to within chemical precision so that's the precision that you need if you're able to do something useful with that knowledge. And the final area is in quantum computers that offer exponentially greater power for some important tasks. For example quantum machine learning would use artificial intelligence type approaches to address what would otherwise be impossibly large datasets and this has applications across all sorts of things ranging from email filters through to online shopping, face recognition, training driverless cars and the list goes on. We've developed a technique at the University of Bristol for using photons in waveguides on a chip and the important point here is that we're guiding those photons around in silicon waveguides on the nanometer scale and this is precisely the same architecture that the conventional computer chip industry is using so they have ambitions to replace all of the copper wires that we currently have in computer chips with these sort of photonic wires. Now apparently Seymour Cray when he was told that Apple had bought a Cray supercomputer to design the next Apple said that's funny I'm using an Apple to design the next Cray and perhaps you would all like to think about how you might use a quantum computer to design the next Apple to design some new medicine etc. Now the really good news here is that you can start you can start trying your hand at this already so just just last week we've made one of one of these devices available online on the quantum cloud and if you log into that email address there you can start programming a small scale photonic quantum processor and I encourage you to have a look at doing that and there's some tutorials along with it that should explain how you can go about doing that. So finally I'd like to acknowledge the European Research Council who've made all of this possible and leave you with a message that quantum technologies are arriving now and my question for you is what you know what would you like to use these technologies for I really want to hear what your problems are because that's that's my main reason for being at this at this forum here is to find out amongst all the applications that I've just touched on and there are more where do you see your business being affected how would you like to apply these things thank you.
