Dr. John Bartholomew, a scientist originally from Corowa, is now at the forefront of quantum computing research at the University of Sydney. His journey began with an insatiable curiosity about how things work, a trait nurtured by his upbringing in a ministerial family. Dr. Bartholomew’s passion for understanding complex systems has led him to lead a team of PhD students focused on developing technologies for a quantum internet, a project that could revolutionize communication and problem-solving capabilities.
Having returned to Sydney six years ago after extensive research in France and the United States, Dr. Bartholomew believes Australia is making significant strides in quantum science. The Commonwealth Scientific and Industrial Research Organisation (CSIRO) estimates that the quantum technology industry could unlock a market valued at $2.2 billion and create approximately 8,700 jobs within the next five years. Dr. Bartholomew states, “There’s real excitement about quantum computing, and it’s quickly becoming an industry effort projected to be worth upwards of $4 billion by 2040.”
The potential applications of quantum computing extend far beyond current capabilities. Dr. Bartholomew emphasizes that it is not simply an evolution of classical computing. “We are trying to zoom in on nature at the level of single atoms and single electrons,” he explains. This new perspective allows researchers to unlock computational power that surpasses even the most advanced supercomputers and artificial intelligence systems available today.
Growing up in Corowa until the age of 13, Dr. Bartholomew credits his formative years for laying the groundwork for his scientific career. The tight-knit community, coupled with a supportive educational environment, fostered his interactions with various people, enriching his understanding of different perspectives and innovations. “I felt very supported by the hard-working teachers,” he recalls, reflecting on his early education.
Dr. Bartholomew also represented Victoria in sports such as hockey, which helped him adjust smoothly after moving to Canberra. His upbringing in a community-oriented environment has instilled in him a sense of responsibility to encourage the next generation of scientists. Recently, he participated in an event hosted by the Sydney Quantum Academy at Xavier Catholic College in North Albury. “If people have an interest in detailed science, whether in quantum or other fields, I’d encourage you to make a contribution, and there are pathways for you to do that,” he stated.
The quantum internet, which utilizes principles of quantum mechanics to enhance communication, is expected to coexist with the current internet. It promises to improve security and enable new capabilities, such as optimizing traffic flow and creating personalized medicine. Dr. Bartholomew stresses that the quantum internet should not be viewed merely as the next mobile phone or the fastest computer; rather, it represents a fundamentally different approach to technology.
His faith, rooted in the Presbyterian Church, has also influenced his professional outlook. “Service to others is really important,” Dr. Bartholomew notes, highlighting how his spirituality guides him in addressing complex challenges. He believes that a broader perspective can lead to solutions that benefit larger communities.
Looking ahead, Dr. Bartholomew encourages students, especially those from regional areas like the Riverina, to pursue careers in advanced scientific fields. “Just because you’re outside of the major city centres, it doesn’t mean that you can’t be involved in these advanced fields,” he remarked. His experiences have shown him that Australians possess a unique ability to innovate and adapt, often finding solutions that work for their circumstances.
As quantum technology continues to evolve, Dr. Bartholomew remains optimistic about the future. He believes that as the technology matures, it will lead to applications yet to be imagined, further expanding the horizons of what is possible in science and technology.
