Quantum computing and artificial intelligence (AI) are converging, promising to push computing boundaries to transform industries and accelerate discoveries. In this article, our CEO Joe Fitzsimons gives his perspective on the approaches to applying quantum computing to AI.

Horizon Quantum Computing, a Singapore-based quantum software start-up, announced today it would build its own testbed of quantum computers, starting with use of Rigetti’s Novera 9-qubit QPU. The approach by a quantum software specialist to build-its-own testbed is new. The idea is to be able to develop and integrate its software stack — Triple Alpha — more thoroughly into various types of quantum computers.

Quantum computers can solve business problems beyond the reach and speed of conventional and classical computers, thus several countries globally have taken steps to encourage the development and adoption of quantum-safe technologies. Horizon’s CEO Joe Fitzsimons discusses quantum-resistant encryption algorithms and quantum cryptography schemes in this article.

Ahead of the TNW Conference in Amsterdam where our CEO Dr Joe Fitzsimons will be a speaker, he sat with Thomas Macaulay to discuss the tremendous potential of quantum computing and our industry’s current challenges, from talent shortage to the need for patient capital.

Quantum computing faces two main challenges to widespread adoption: the development of hardware capable of supporting quantum computation at scale and the creation of software tools that allow programmers to harness this hardware to solve real-world problems. Founded in 2018, Horizon is focused on the second challenge, that is, building a system for quantum software development that enables developers to bridge the gap between classical code and quantum accelerated applications.

Horizon announced a round of $18.1 million to expand its engineering team and speed up product development. The company, founded in 2018, created a programming language called Helium, designed to bridge the gap between classical and quantum computers.

Relying on cloud-based hardware presents a number of barriers to industry adoption of quantum computing. A Quantum Computing Report article discusses how blind quantum computing may help overcome these barriers and highlights Horizon’s contribution to this technology.

Breakthroughs in quantum computing keep coming, but there aren’t many people with the expertise to make use of it. CEO Dr Joe Fitzsimons talks about how Horizon is making quantum computing accessible by building the tools necessary for real-life applications. 

Systematic means of benchmarking the performance of a quantum processor are still mostly missing. Xiao Yuan, Yunchao Liu, Qi Zhao, Bartosz Regula, Jayne Thompson (Horizon’s Technical Product Manager) and Mile Gu studied a practically meaningful, experimentally accessible, and universally relevant quantifier of a memory’s capability to preserve the quantum advantage. This measure applies unilaterally to all platforms, allowing us to benchmark processors across different architectures.

Singapore, a skyscraper-laden, tropical paradise known for its business-friendly policies. With the second-highest GDP per capita (PPP) in the world, it’s no wonder this island city-state — one of the Four Asian Tigers — has some of the most innovative startups in the world. This goes for startups in the quantum tech ecosystem, too, with a handful so far founded within the last half a decade.

Dr Si-Hui Tan had already developed a keen interest in mathematics and science in secondary school. From Raffles Girls’ School she went on to pursue advanced mathematics and a degree in physics, and eventually earned herself a post-doctorate degree in physics at the Massachusetts Institute of Technology (MIT). Today, the 40-year-old is the chief science officer at a local start-up, Horizon Quantum Computing. The company aims to make quantum computing more accessible to software developers.

Driven by the vision of quantum computing as a revolution in computing technology, Joe Fitzsimons 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.

Identical particle entanglement can be coaxed into mediating other forms of entanglement that are already widely used in quantum computing and communications technologies, as recently demonstrated by a team of researchers from the University of Nottingham and University of Basel. Horizon's Technical Product Manager Jayne Thompson offered her opinion as part of a Scientific American article about the study.

Science Magazine puts the spot on quantum illumination, often dubbed "quantum radar", and the important role played by work that our Chief Science Officer Si-Hui Tan did during her PhD at Massachusetts Institute of Technology, back in 2008, comparing quantum with entangled photons and coherent states.

Late last year, the world of quantum computing achieved a significant milestone. A quantum processor developed by Google was able to solve a complex mathematical calculation in just three minutes and 20 seconds. In comparison, the most advanced supercomputer to date would have taken more than 10,000 years to solve it.

Quantum technologies can be designed more efficiently if they can be trained in self-improvement. A team of researchers in Singapore and China, including Jayne Thompson, who recently joined Horizon Quantum Computing as a Technical Product Manager after doing research for Centre for Quantum Technologies, have demonstrated this potential through engineering a new method to machine learn quantum-enhanced probes for precision sensing applications.

No matter how fast. No matter how powerful. No matter how many qubits can be entangled. No matter how long those qubits can remain entangled. The quantum computer industry will never reach its full potential unless people can actually use quantum computers. Horizon Quantum Computing, a Singapore-based quantum startup, was founded with the mission of making quantum computing more people-friendly in mind, according to Joe Fitzsimons, the company’s CEO.

Quantum computing has gained significant interest over the years because of its potential to solve problems beyond the reach of the most powerful supercomputers. Singapore’s Horizon Quantum Computing is a startup that aims to make quantum computing much easier to access and in turn become a part of a bigger tech revolution.

Horizon Quantum is part of a new crop of startups that focus on building new tools for building software for quantum computers. The Singapore-based company, which is hardware-agnostic but also launched a close partnership with Rigetti Computing in 2018, today announced that it has raised a $3.23 million funding round led by Sequoia Capital India. Previous investors SGInnovate, Abies Ventures, DCVC, Qubit Protocol, Summer Capital and Posa CV also participated.

“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.”
