QuNaT ported
We’ve brought over the news posts from qunat.org – the previous home of the research group. You can read these posts after this one.

Use small modules? OK, but how small?
Many researchers believe that the best way to make a quantum computer is to interlink many small modules. But what does “small” mean? In particular, will be quantum machine be more powerful (or perhaps, more resistant to errors) if it each module is itself a powerful device with 100’s of qubits? Read more…

Quantum annealing
The process called quantum annealing is a hot topic! We’ve posted a preprint which extents recent ideas from an Innsbruck team, for realising such a technology in a powerfully flexible form. The word ‘annealing’ usually refers to a process where a metal is heated and slowly cooled (see image). But in quantum annealing a system is slowly Read more…

Quantum Learning with Nokia & Lockheed Martin
A new project on Quantum Optimisation and Machine Learning “QuOpaL” is now underway. Based at the University of Oxford, it’s a joint endeavour between the University, Nokia and Lockheed Martin. The aim of the project is to understand the potential for quantum technology to enhance optimisation and machine learning tasks Read more…

Ultimate network?
In a paper to appear in PRX, Naomi and Simon present detailed calculations simulating a quantum computer built from many small units — each unit being similar in complexity to the devices that can already be created in the lab. They find than an architecture involving connecting up many Read more…

Going 100% open!
The last few papers from the QuNaT group have set a precedent that we hope to maintain permanently: We publish in open journals so that our papers can be read by everyone, everywhere without needing to (a) belong to an institutional library, or (b) pay a ~$30 fee to pass Read more…

Where quantum meets the rest of the world
A quantum system interacting with an environment can behave very differently to when it is in isolation. This can be a problem when modelling messy biological systems – how do I describe the molecule I’m interested in without describing the rest of the surrounding chemical soup? In a recent manuscript that’s Read more…

More Bird Brains
The debate continues about quantum effects in the natural ‘compass sense’ that some birds have. The most well-studied species is the European Robin, shown in this picture: We’ve just published a Comment in PRL, with our counter arguments to some of the claims in a recent Letter there. Read it Read more…

A thousand fragments
Our recent paper in Nature Communications explains how we might be able to break up a quantum computer into little, easy to make pieces and then network them together. Read more about it at the Oxford University science blog here. …or the Singapore Centre for Quantum Technology story here. Below Read more…
