Global VC bets on Australian quantum computing start-up Q-CTRL in US$15m Series A

 The investment from top VCs will ensure Q-CTRL’s ‘quantum firmware’ becomes ubiquitous in the race to build the first practical quantum computers

Media Release, Tuesday 10 September EDT, Boston, Massachusetts, USA  – Quantum computing start-up Q-CTRL has completed a US$15million Series A round led by Australia’s largest venture capital fund, Square Peg Capital and adding new syndicate member, Silicon Valley’s Sierra Ventures.

The round also includes participation from existing investors including Sequoia Capital, Main Sequence Ventures, and Horizons Ventures.

This investment places Q-CTRL in the top 10 most successful fundraisers globally in the emerging quantum technology industry, and constitutes one of Australia’s largest VC deals for 2019.

Since its founding in 2017, Q-CTRL has rapidly established itself as a global leader in the quantum computing space.  In 2018 it was named as the only company outside of North America to be included in IBM’s hand-picked network of startups working to advance the emerging quantum computing industry.

The capital raise will support major growth, roughly doubling the existing 25-member team of quantum engineers and software developers.  In addition, it will support geographic expansion to include a new office in Los Angeles, bringing Q-CTRL staff closer to core customers in the US.  

Q-CTRL provides a globally unique offering and fills a niche building “infrastructure software” to aid the development of quantum computers and other quantum technologies.

The company specializes in solving one of the hardest problems in quantum computing – hardware instability against noise and errors.  Quantum computers are notoriously fragile; the machines being developed now by companies like Rigetti and IBM can only run operations for very short periods before errors creep in and programs fail. 

That fragility puts at risk the potential promise of quantum computers to revolutionize drug discovery, chemistry, and even computations for finance.

Professor Michael J Biercuk, Founder Q-CTRL

Founded by Professor Michael J Biercuk, the company produces “quantum firmware” – a set of special low-level programs that allows quantum computing hardware to be more resistant against errors. 

Michael is a Professor of Quantum Physics & Quantum Technology at the University of Sydney and a Chief Investigator in the Australian Research Council Centre of Excellence for Engineered Quantum Systems. He was educated in the United States, earning a PhD in Physics from Harvard University and a BA from the University of Pennsylvania.

Q-CTRL’s solutions are demonstrated to reduce hardware-error susceptibility by orders of magnitude, accelerating the pathway to the first commercially relevant quantum computers.  Q-CTRL currently has among its customers Rigetti, Bleximo, Accenture, and many others.

“Being at the vanguard of the birth of a new industry is extraordinary,” says Professor Biercuk.

“We’re also thrilled to be assembling one of the most impressive investor syndicates in quantum technology.  Finding investors who understand and embrace both the promise and the challenge of building quantum computers is almost magical.”

Square Peg Capital investment partner Tushar Roy says Q-CTRL has the potential to be instrumental in the future development of quantum computers.

“Q-CTRL impressed us with their strategy; by providing infrastructure software to improve quantum computers for R&D teams and end-users, they’re able to be a central player in bringing this technology to reality,” says Mr Roy.

“Their technology also has applications beyond quantum computing, including in quantum-based sensing, which is a rapidly-growing market.

“In Q-CTRL we found a rare combination of world-leading technical expertise with an understanding of customers, products and what it takes to build an impactful business.”  

Ben Yu, Managing Director at Sierra Ventures, an early stage tech venture capital firm based in Silicon Valley, said his team has been looking for a promising quantum computing company for some time.

“As emerging and deep technology investors, we have been patiently looking for opportunities in quantum computing but knew that noise and error were this technology’s Achilles heel,” says Mr Yu.

“We were ecstatic when we discovered Q-CTRL, which provides solutions to overcome this problem on any quantum computing hardware. We see Q-CTRL’s offerings as not only essential to the industry in the long term, but critical to accelerating the pathway to the first useful applications of quantum computing.”

Q-CTRL was founded in November 2017 and is a venture-capital-backed company that provides control-engineering software solutions helping customers harness the power of quantum physics in next-generation technologies.

Q-CTRL is built on Professor Michael J. Biercuk’s research leading the Quantum Control Lab at the University of Sydney, where he is a Professor of Quantum Physics and Quantum Technology.

The team’s expertise led Q-CTRL to be selected as an inaugural member of the IBM Q startup network last year. Q-CTRL is funded by SquarePeg Capital, Sierra Ventures, Sequoia Capital, Data Collective, Horizons Ventures, and Main Sequence Ventures. In February 2019 it was named one of the 10 top quantum computing startups to watch by tech publication Network World.


Professor Michael J. Biercuk is an award-winning experimental quantum physicist and CEO & founder of Q-CTRL. He is one of the world’s leading experts in the new emerging field of quantum technology; the work he is doing promises to be as transformational in the 21st century as harnessing electricity was in the 19th.

Michael also holds the positions of Director of the University of Sydney’s Quantum Control Lab and Chief Investigator in the Australian Research Council Centre of Excellence for Engineered Quantum Systems. He was educated in the United States, earning a PhD in Physics from Harvard University and a BA from the University of Pennsylvania.

He served as a technical consultant to DARPA, the premier research funding agency in the US from 2005-08, providing advice on strategic technology investments. He moved to Australia in 2010 as a Senior academic at the University of Sydney and was promoted to Full Professor at the age of 37. 

He is a TEDxSydney and SXSW speaking alumnus, is the recipient of the 2015 Eureka Prize for Outstanding Early Career Researcher, and was named a finalist in the 2019 Australian Museum Eureka Prize for ‘Promoting Understanding of Science’.
