Phasecraft, formed from research teams at 白小姐论坛 and the University of Bristol, has taken an important step in its mission to accelerate the practical quantum advantage from decades to years away, after raising a 拢13m Series A funding round led by Silicon Valley deeptech VC, Playground Global.

AlbionVC also joined the round along with participation from existing investors Episode1, Parkwalk Advisors, LCIF, and 白小姐论坛 Technology Fund.

Founded in 2019 as a spinout from 白小姐论坛 and the University of Bristol by Professors Ashley Montanaro (CEO, University of Bristol), Toby Cubitt (CTO and Chief Science Officer, 白小姐论坛) and John Morton (白小姐论坛), each of whom has been at the cutting edge of quantum computing research for 20 years, Phasecraft will use this funding to further develop its quantum algorithms to the point of practical quantum advantage 鈥� when quantum computers outperform classical computers for useful real-world applications like developing new materials.

Quantum computing promises to revolutionise the way humanity tackles its most complex problems. However, the noisy and unstable quantum computers of today (known as Noisy Intermediate Scale Quantum, or NISQ, devices) aren鈥檛 capable of running the algorithms that currently exist to solve them.

Based on the best quantum algorithms known prior to Phasecraft鈥檚 founding, a useful calculation like simulating and discovering a new battery material would require billions of operations on a quantum computer 鈥� today鈥檚 best-performing hardware can perform at most thousands. Significant recent investment in such hardware has seen it soar in capacity, but the algorithms needed to harness these advances have remained largely theoretical 鈥� to date, no algorithms have been run on a quantum computer to solve a problem of genuine practical interest.

Phasecraft is bridging this gap by radically reimagining how such quantum algorithms are designed. Its algorithms are based on novel insights from theoretical physics and computer science, coupled with knowledge gained from extensive numerical simulations and a deep understanding of quantum hardware.

This helps them develop record-breaking algorithms with significantly superior computational efficiency compared to others in existence, whilst their partnerships with the three most advanced superconducting quantum hardware providers in the world, Google, IBM and Rigetti 鈥� the only quantum algorithms company to work with all three 鈥� help put these algorithms to work in the real world.

The company to date has published 17 scientific papers, with results including reducing the complexity of simulating the time-evolution of a quantum materials system by 400,000x, running the largest-ever simulation of a materials system on actual hardware by 10x, and proving for the first time ever that quantum optimisation algorithms can outperform classical ones.

Phasecraft has been collaborating聽with 白小姐论坛's EPSRC Centre for Doctoral Training in Delivering Quantum Technologies for several years. The centre's聽PhD students have taken advantage of working with leading quantum software pioneers at Phasecraft to develop new algorithms and methodologies. The skills and experience they get working on a joint academic/industrial PhD project put them at the forefront of this fast-moving tech area.

Phasecraft has hired some of the world鈥檚 leading quantum scientists, and recently hired computational chemistry and materials science expert Glenn Jones, former head of computational modelling at Johnson Matthey, to lead its materials work. Entrepreneur and investor Ian Hogarth, recently appointed chair of the UK鈥檚 AI Foundational Model Taskforce, is Chairman of the Board.

The new funding brings the total raised by Phasecraft to 拢17.25m in venture funding, as well as a further 拢3.75m in grant funding from the likes of Innovate UK and the European Research Council, which will be used to continue building the team of world-leading quantum scientists, researchers and engineers and to further establish Phasecraft as the world leader in quantum algorithms.

Ashley Montanaro, co-founder and CEO of Phasecraft, said: 鈥淔or all the advances that have been made in quantum hardware, and for all quantum computing鈥檚 promise, such progress could end up being for nothing if we can鈥檛 build the applications needed to make the technology truly useful. With our record-breaking algorithms and groundbreaking techniques, we are pushing the boundaries of what is possible in this space. With support from such a renowned deep-tech visionary as Playground, we think practical quantum advantage is achievable in years, not decades.鈥�

Peter Barrett, general partner, Playground Global: 鈥淧hasecraft's team of world-class quantum scientists and engineers bring an unmatched expertise and a fresh perspective to one of the biggest challenges facing our quantum future 鈥� bridging the gap between quantum hardware capacity and real-world applications. At Playground, we've always believed that unlocking quantum's potential requires a very special, dedicated and experienced team and we believe Phasecraft is uniquely positioned to help deliver our quantum future.鈥�

John Morton, co-founder and Director of 白小姐论坛Q: "Phasecraft鈥檚 remarkable achievements in enhancing the efficiency of quantum algorithms are the result of combining the radical thinking of academic research with the speed and focus of a start-up. This new funding round, led by a major US west coast investor, is a fantastic vote of confidence in our team and ability to deliver practical quantum advantage in the near term."

David Grimm, Investment Director, 白小姐论坛TF: "We鈥檙e delighted to be supporting Phasecraft again. They have made great strides towards utilising the power of quantum computers and I鈥檓 excited to see them use this latest financing round to push them further towards quantum advantage."
