Why is it so hard to build a quantum computer? We believe that the future is quantum – and Microsoft is committed to empowering this revolution. The quantum circuit itself is very small – smaller than the eye can see. I am very excited to work with industry and government to make this happen.” The team has yet to construct a prototype using their blueprint. The blueprint is for building quantum computers at an industrial scale. What we don’t know, just yet, is the connection between the two sets of rules. A house of cards gets bigger and more unstable, whereas a Lego structure gets bigger and stronger. With a publicly available blueprint, more scientists could actually collaborate to improve this technology, which would bring us closer to more practical quantum computers. And we want you to be a part of it too. We believe that the future is quantum – and Microsoft is committed to empowering this revolution. With a topological circuit, built with topological qubits, we have something more like Lego bricks. With Lego, you can more easily connect the bricks together, and build huge structures without making the structure weaker. Microsoft, Data & AI and Digital Transformation. These scientific breakthroughs are only possible with the help of engineering and theory, working together. We don’t have all the answers to this question. Why do we need to cool the circuit down with such big machines? I understand and agree that registration on or use of this site constitutes agreement to its User Agreement and Privacy Policy, solve the most complex of science’s problems. Well, we need to get them down to almost absolute zero – zero Kelvin – to make the dominant behaviour in those chips quantum. A new Microsoft laboratory at the Delft University of Technology is the latest step towards making quantum computing a reality. You can no longer simply look up an item’s recipe online and get crafting away, even for some of the more basic valuable products like Herox or Lemmium. What we need to do – to build a quantum computer – is use our classical understanding to build and control a quantum system. Traditionally, building a quantum circuit is like building a house of cards. But it’s not the quantum mechanics as in atoms and molecules. And we want you to be a part of it too. With a stable topological qubit, we can scale quickly, and help to solve some real-life problems with quantum computing. By connecting a quantum computer to the Azure cloud platform, we can make this computational power available to many more people – and empower them, and you, to do amazing things. They are likely to take up entire buildings, not just space on an office desk. Join us at the leading edge of opportunity, Microsoft’s new quantum computing lab opens its doors to a world of possibilities. They are intended to be built alongside individual sophisticated vacuum apparatus and integrated quantum computing silicon microchips where the ions are stored using electric fields. This technology is a game changer for many industries, and an international team of scientists unveiled today the first practical blueprint to build your own quantum computer. Read more Microsoft’s new quantum computing lab opens its doors to a world of possibilities. We asked Professor Leo why it’s so difficult to build a quantum computer. In our world – the world of falling balls and apples – the rules are classical. However, this quantum computer won’t be replacing your home computer just yet. “The availability of a universal quantum computer may have a fundamental impact on society as a whole. How to Get Quantum Computers. We’re using classical signals and objects and attempting to ‘bring to life’ the quantum behaviour in those materials. Share this post. Eventually, quantum computing could truly become available to all. At these very low temperatures, achieved by metres’-tall refrigerators, we can make things quantum. At room temperature, everything is classical, not quantum – where objects are in superposition. Putting quantum computing to work It takes only one operation to go from a classical computing state that looks like either a 0 or a 1, to a superposition state, where the information can be … That is, in two different positions at the same time. Without doubt it is still challenging to build a large-scale machine, but now is the time to translate academic excellence into actual application building on the UK’s strengths in this ground-breaking technology. Regular computers use bits (0s and 1s) to represent data. Our collaborative approach to quantum means we can speed up scientific learning and take computing to the next level. Professor Leo Kouwenhoven is a key member of Microsoft’s quantum team – and leads a team of researchers and engineers at the Microsoft Quantum Lab in Delft, in the Netherlands. By connecting a quantum computer to the Azure cloud platform, we can make this computational power available to many more people – and empower them, and you, to do amazing things. If you haven’t played No Man’s Sky in some time, you’d be forgiven for not understanding how some things have changed. Well, compared to the computers we have in our pockets today. It’s what’s called ‘topological’. This is due to a strange quantum phenomenon called “superposition” which makes quantum computers more capable of handling computational processes. You might think that a quantum computer is really small, because we’re making use of smaller particles to make a quantum circuit, but that’s not entirely true. There are only a few quantum computers currently in existence, like D-Wave’s controversial quantum computers. Quantum computers, on the other hand, rely on quantum bits (or qubits) that could be a 0 or a 1 at the same time. Related. Such a machine would absolutely revolutionize our ability to solve the most complex of science’s problems, develop superior lifesaving medicines, help explain the universe’s deepest mysteries, and more. According to lead author Bjoern Lekitsch, “It was most important to us to highlight the substantial technical challenges as well as to provide practical engineering solutions.” The team’s blueprint features an innovative design that allows actual qubits to be transmitted between individual quantum computing modules. You remember those? But, without a doubt, when quantum computers become more accessible, these powerful machines will change the world. Still, this is a huge step in making quantum computers more universally accessible. And that’s not something you’d want to put in your pocket! Quantum computers operate at a different level compared to today’s regular computers, due primarily to how they process and encode information. This “superposition,” however, is incredibly difficult to sustain. Here we use electronic chips – and we design and control them in such a way that the dominant behaviour of the electrons in those chips is quantum.
