The Algorithms Bottleneck
With hardware on the way, the race is on to develop new applications for these systems. More than 240 leading researchers from academia and industry recently signed the Quantum Software Manifesto highlighting the need for investment in quantum software development. Unfortunately, there are significant barriers to developing useful quantum software.
Quantum mechanics defies our intuition, making it difficult to construct non-trivial algorithms.
Developing non-trivial quantum algorithms and protocols requires years of experience.
Limited Talent Pool
Only a small community of researchers have experience developing quantum algorithms.
Lack of Necessary Tools
Little work has been done on quantum data structures and languages remain assembly-like.
At Horizon, we think about the challenge of programming quantum computers differently. Rather than relying on libraries of pre-programmed algorithms or requiring programs to be written using gate level languages, we think that you should be able to program a quantum computer in exactly the same way you program computers today. That’s why we’re pioneering an approach to quantum programming that allows programs written in a single unified language to be compiled and run on either conventional or quantum computers, producing fast efficient implementations no matter the platform. At the core of our technology is a process that automatically constructs quantum algorithms based on programs written in Matlab or Octave.
Source code is first parsed and then recast in a form that untangles and simplifies the code so that quantum speedups can be more easily detected. Elements of the program are then classified and replaced with more efficient quantum subroutines which accomplish the same task in different ways. Finally, these are translated into the basic building blocks of quantum algorithms and processed into a quantum program. This allows the programmer to gain a quantum speedup without the need to understand the underlying computational model and without having to restrict themselves to the limited functionality of pre-existing libraries. This allows greater flexibility and the opportunity to develop quantum algorithms for new domains without deep quantum expertise.
A Full Compiler Stack
The functionality of our system goes beyond simply constructing algorithms. We are developing a complete compiler stack that will span the entire chain from algorithms construction down to physical level implementation.
At Horizon Quantum Computing, we are an interdisciplinary team of physicists and computer scientists trained in top-tier science and engineering universities. Individually, we are recognized specialists in quantum computing, and have published extensively in peer-reviewed journals. Aided by dedicated and experienced non-technical staffers, we are passionate about finding real-world uses for quantum computers, and are working closely together to develop a full-stack optimising compiler for quantum processors.
Dr Joe Fitzsimons
Chief Executive Officer
Driven by the vision of quantum computing as a revolution in computing technology, Joe quit his tenured faculty position to found Horizon Quantum Computing in 2018. Drawing on over 15 years’ experience in quantum computing and computational complexity theory, today he fully dedicates his time to Horizon with the goal of making quantum computing a general purpose computing technology capable of addressing some of the world’s most challenging computational problems.
Joe received a BSc in Theoretical Physics from University College Dublin and a DPhil from Oxford, where he went on to become a fellow of Merton College. Prior to founding Horizon, he led the Quantum Information and Theory group at Singapore University of Technology and Design, where he was a tenured associate professor, and was a principal investigator at the Centre for Quantum Technologies. He has published at the highest levels in both theoretical computer science (FOCS, STOC, CCC, ITCS) and physics (Science, Nature Physics, Physical Review Letters, Physical Review X), and has been named as a National Research Foundation Fellow and to the MIT Technology Review Innovators Under 35 Asia list.
Dr Si-Hui Tan
Chief Science Officer
Si-Hui has broad experience of quantum information science, having been an active researcher in the field for 15 years. She received a BSc in Physics from Caltech and a PhD in Physics from MIT. Si-Hui joined Horizon Quantum Computing, shortly after its inception, to pursue the ambition of making quantum computers a reality for everyone. At Horizon, she heads the research development and helps to oversee daily operations.
Prior to joining Horizon, she has worked as a research scientist, initially at A*STAR’s Data Storage Institute, and subsequently at Singapore University of Technology and Design and the Centre for Quantum Technologies.
Si-Hui has published extensively in top physics journals, including Physical Review Letters and Physical Review X, and in well-known conference proceedings such as the IEEE Information Symposium on Information Theory and the SPIE International Symposium on Optics and Photonics.

“After an academic career at top universities in Ireland, the U.K. and Singapore, Joe Fitzsimons spun off Horizon Quantum Computing, a quantum software company, from CQT in 2018. The tipping point was on the horizon, he said, and he wanted to be established by the time one of the big tech companies announced that they had achieved quantum supremacy.
“Everyone in the field has known this was coming,” he said. “We thought: Once this result is announced, there’s going to be this rush of people looking to start companies. … I think the day following the Google announcement, I got contacted by three VCs.”

UTS Centre for Quantum Software and Information invited Dr. Joe Fitzsimons, CEO of Horizon Quantum Computing, to present a virtual seminar hosted by Prof Michael Bremner. In this talk, Dr. Joe Fitzsimons introduced some of the work we have been doing at Horizon Quantum Computing to simplify the task of programming quantum processors through increasing levels of abstraction, and discuss progress towards our goal of compiling classical code to take advantage of quantum processors, through automated synthesis of quantum algorithms.
The a recording of the seminar is available on YouTube here.

Horizon Quantum Computing CEO Dr. Joe Fitzsimons was one of the participants at Rigetti Advantage 2020, where he presented progress on characterising quantum processors and mitigating the effects of errors through frame updates and decoupling methods. To enable this work, Horizon was granted early access to Rigetti’s Quilt framework which was publicly announcement at the event.

Horizon Quantum Computing is proud to sponsor Q2B 2019. Organized from 10 to 12 December in San Jose, California, this three-day conference brings industry, government and research institutions together to stimulate application discovery and development. Dr. Joe Fitzsimons, CEO of Horizon Quantum Computing, will be sharing the company’s latest achievements at the talk “From queues to qubits: compiling classical code for quantum processors”.
24 October 2019
“Quantum advantage means demonstrating computational supremacy for a meaningful problem, showing that a quantum processor has been built which is more useful than a conventional computer for at least one problem,” said Fitzsimons. “The path to large-scale quantum computing is more of a marathon than a sprint. The current result certainly places Google at the front of the pack, but there is still a long way to the finish line.”

Today we are delighted to announce that we have entered into a partnership with Rigetti Computing. At Horizon Quantum Computing, we are building a new generation of programming tools that will allow developers with little or no prior exposure to quantum computing to harness the full power of quantum processors. The partnership with Rigetti marks the first step towards this goal, allowing us access to Rigetti’s state of the art quantum processors, and will see us making new programming tools available to Rigetti customers through their Quantum Cloud Services in the future. We look forward to working with Rigetti as we enter a new era in computing technology.
