Mild cooling technology
Can we build a million qubit quantum computer?
Yes, we can and we will. For us, it’s not about fundamental breakthroughs.
We will achieve the seemingly impossible through our six technology pillars:
Many other quantum computing platforms require cooling close to milli Kelvin temperatures (i.e. absolute zero or -273C). But with such limited cooling power available at that temperature, scaling to millions of qubits is incredibly hard to achieve.
We take a different approach. Our technology only requires cooling to 70K, providing ample of cooling power which scales to millions of qubits.
We use individual charged atoms – ions – as our qubits.
Each ion levitates above the surface of a silicon microchip. Because the qubits are naturally identical, well isolated from the environment and easily controllable, ‘trapped ion’ quantum computing is the most mature quantum computing technology.
Trapped ion quantum computing holds world records in almost all the important specifications, such as errors for single / two qubit quantum gates, connectivity and decoherence time.
Trapped ion quantum computers generally use pairs of laser beams that must be aligned to the position of individual ions to execute quantum gates. This requires alignment accuracy to a fraction of the width of a human hair. But imagine trying to align millions of laser beams with such incredible accuracy, while stabilising each one’s power, position and phase – in the knowledge that the slightest deviation would stop the quantum computer from working.
We use a much simpler electronic gate technology. Our quantum gates are executed by applying voltages to a microchip, similar to how classical transistors operate. We base our approach on the mature microwave technology used in today’s mobile phones.
We’re developing fully electronic quantum computing modules based on integrated silicon microchips which capitalizes on the wealth of expertise that has come out of the development of the silicon microchips used in conventional computers. The result is fully integrated self-contained electronic quantum computing modules.
We are truly passionate about ensuring our technology scales to quantum computers with millions of qubits. With a single wafer holding just a few thousand qubits at most, modularity is critical to achieving this feat. One proposed method for achieving this uses photonic interconnects, with optical fibres connecting different quantum computing modules. The connection speeds of this extremely complicated technology after years of intense research are low while there is also no simple engineering solution available. This would therefore provide a potentially unsurmountable bottleneck when scaling up.
We take a completely different approach to modularity, which uses electric field links between adjacent quantum computing modules. As well as using much simpler engineering, it will enable connections between modules that are orders of magnitude faster.
There are many theories about how to build a million-qubit quantum computer, but none of them has a ‘nuts and bolts’ delivery plan – except ours. In 2017 we drafted the first practical blueprint to build a quantum computer with millions of qubits, supported by realistic engineering considerations. It underwent years of scrutiny before publication, and its authors include some of the leading experts from around the world. You can read more about it here.
At Universal Quantum, we don’t just deliver the physics – we also develop truly innovative engineering solutions. Humanity needs a quantum computer with millions of qubits and we we’re bringing together a world-leading truly interdisciplinary team to build exactly that.
We’re building quantum computers to tackle real-world problems that would take today’s fastest supercomputers billions of years to solve.
That’s our ambition. From medicine to finance and much more, our work will transform the world.
To help us achieve our bold ambitions, we’re guided by these principles:
We’re dedicated to revolutionizing quantum computing by delivering the most innovative solutions, so humanity can enjoy the benefits of this ground-breaking technology. Our team are world-class, global pioneers in quantum computing and engineering research and development. By continuing to attract the best talent, Universal Quantum is establishing a hub for the most innovative engineers and scientists that will deliver the seemingly impossible.
We always challenge the status quo, because that’s the catalyst for finding new solutions. While our competitors focus on lasers, our approach uses microwave technology such as used in mobile phones.
We’re tackling engineering integration rather than ground-breaking physics. Thinking and acting differently is part of who we are and what helps us be successful – what better location to do this at than the cosmopolitan and creatively dynamic city of Brighton, UK.
Universal Quantum is a fraction of the size of major companies within the quantum sector, such as IBM and Google but it has the technology solutions to transform the sector. At Universal Quantum we’re all engineering enthusiasts, but it’s our differences that define our truly interdisciplinary team.
Just as the power of a quantum computer is greater than the sum of its parts, our international team creates an inclusive environment that enables critical breakthroughs to help deliver our vision. We’re proud to be working towards such a transformative paradigm change, and we constantly inspire each other to solve the impossible.
