World Quantum Day is celebrated on April 14 in the world, a special day to find out the exciting power of quantum technology. Australia is also an important part of this journey.
Thanks to smart researchers in institutions like the University of Sydney and Australian National University, Australian startups are turning quantum ideas into tools that will change our world. They are making ultra-intelligent computers and discovering new ways of securing information. Let’s spotlight the four awesome startups driving this futuristic wave.
Q-CTRL

Q-CTRL started in November 2017 at the University of Sydney. It was created by Professor Michael J. Biercuk, an expert in quantum physics who runs the Quantum Control Lab. Q-CTRL makes special software called quantum firmware. This software helps quantum computers work better by fixing errors. Errors happen when noise or tiny shakes mess up calculations. Q-CTRL’s tools make quantum machines more reliable, so they can solve big problems like designing new medicines or improving traffic systems.
Professor Biercuk’s team works with companies like Rigetti, Bleximo, and Accenture, who trust Q-CTRL to make their quantum technology stronger. Investors include Square Peg Capital, Sierra Ventures, Sequoia Capital, Data Collective, Horizons Ventures, and Main Sequence Ventures. Q-CTRL is like a mechanic for quantum computers, making them run smoothly so they can help everyone soon.
Cool Facts:
- Q-CTRL was named one of the top 10 quantum startups to watch by Network World in 2019.
- It was chosen for IBM’s special quantum startup group, showing it’s a world leader.
- The team’s software reduces errors a lot, helping quantum computers get ready for real jobs.
Quantum Brilliance
Quantum Brilliance team
Quantum Brilliance began in 2019 at the Australian National University in Canberra. It’s an Australian-German company that builds small quantum machines called quantum accelerators. Most quantum computers need very cold temperatures or big lasers, but Quantum Brilliance uses synthetic diamonds. These diamonds let their machines work at normal room temperature, so they are small and use less energy. This makes them perfect for places like cars, satellites, or offices. The company’s founders invented new ways to make diamond-based quantum chips and work with customers to create easy-to-use software.
Quantum Brilliance is one of the few companies giving quantum machines to clients who use them in their own buildings. Investors include Main Sequence, In-Q-Tel, Intervalley Ventures, National Reconstruction Fund Corp., Breakthrough Victoria, Alium Capital Management, Investible, and Jelix Ventures. Quantum Brilliance is like a magician, turning diamonds into tiny computers that can go anywhere, spreading quantum power around the world.
Cool Facts:
- Quantum Brilliance won a contract to build the world’s first mobile quantum computer by 2027.
- Their machines use diamonds and work at room temperature, no cooling needed.
- They teamed up with a U.S. lab to mix quantum machines with regular computers for AI.
QuintessenceLabs
Dr. Vikram Sharma, CEO of Quintessence Labs
QuintessenceLabs, based in Canberra, leads the way in quantum cybersecurity. Founded in 2008 by Dr. Vikram Sharma, the company was born from world-class research he conducted with the Australian National University’s Quantum Optics Group. Sharma, who holds a PhD in quantum physics from ANU, also brings a strong business edge, with degrees from Stanford and ANU and over 20 years of experience building and running tech companies, including one of India’s first private ISPs and an IT consultancy for the Australian federal government.
His work at QuintessenceLabs is focused on a big challenge: securing data in a world where quantum computers could one day crack traditional encryption. The company uses quantum key distribution and true random number generation, technologies that create codes even the most powerful future machines can’t break. These tools are already helping banks, governments, and enterprises keep their systems safe.
Backed by investors like Main Sequence, TELUS Ventures, InterValley Ventures, and Capital Property Group, QuintessenceLabs is recognized globally for its innovation. Think of it as a digital bodyguard powered by quantum science — protecting the world’s most sensitive data in the age of quantum computing.
Cool Facts:
- QuintessenceLabs was named a World Economic Forum Global Innovator.
- They won a 2020 CyberTech100 Award as a top cybersecurity company.
- Their tools make secret codes that are impossible to crack, keeping data safe.
PsiQuantum

PsiQuantum is based in Palo Alto, California, but it has a big project in Australia. Started in 2015, the company wants to build the world’s first fault-tolerant quantum computer. This means a computer that works perfectly and can solve very hard problems. They use light particles, called photons, to make their quantum chips.
These chips are special because they can be built with the same machines used for regular computer chips, making them easier to create in large numbers. In Australia, PsiQuantum is working with the Australian and Queensland governments to build a huge quantum computer near Brisbane Airport. This project will be ready by the end of 2027. Investors include the Australian Commonwealth and Queensland Governments through equity, grants, and loans. PsiQuantum’s work is like building a super-smart brain for Australia, bringing powerful technology to Queensland and creating jobs for the future.
Cool Facts:
- PsiQuantum’s Brisbane computer will help industries like energy, health, mining, and transport.
- Their quantum chips use light particles, making them easier to build in large numbers.
- The Brisbane project will be ready by 2027, making Australia a quantum leader.
