Dr. John Bartholomew, a former schoolboy from Corowa, is now at the forefront of quantum computing research. Leading a group of PhD students at the University of Sydney, he is dedicated to developing technologies that aim to create a quantum internet. This transformative field could revolutionize how we communicate and solve complex problems, propelling Australia into a new era of technological advancement.
Growing up in Corowa, Dr. Bartholomew was fueled by an insatiable curiosity. Born in Albury to ministerial parents, Arnold and Joy Bartholomew, he was often found tinkering with various devices, from record players to typewriters. Reflecting on his childhood, he said, “I was very frustrated when I didn’t understand how things worked.” This early fascination laid the groundwork for his successful career in quantum science.
After gaining international experience in quantum information science in France and the United States, he returned to Sydney six years ago. His work in the field has positioned him as a key player in Australia’s burgeoning quantum technology sector. The CSIRO, Australia’s scientific research agency, estimates that this industry could be worth approximately $2.2 billion and create around 8,700 jobs in the next five years.
Dr. Bartholomew expressed enthusiasm for the potential of quantum computing. “The application space to improve how we can solve problems is really large; even the ones we’re thinking about now are exciting,” he noted. He compared the current stage of quantum technology to the early days of classical computing, when innovations were being made for simple devices like hearing aids and radios. He anticipates that as quantum technology evolves, it will lead to unexpected applications that could significantly enhance our daily lives.
During his formative years in Corowa, Dr. Bartholomew benefited from a supportive community and a variety of sports activities. He represented Victoria in hockey and credits his upbringing with instilling a sense of curiosity and collaboration. “I was growing up in an environment where I was talking and interacting with a whole range of different people,” he recalled. This interaction helped him transition smoothly when his family moved to Canberra.
Quantum technology underpins many familiar technologies, including GPS and medical imaging. Yet, the race is on to develop computers capable of solving new, complex problems. A quantum internet would leverage quantum mechanics to connect quantum computers and sensors, allowing for more secure communications and advanced capabilities in areas such as traffic optimization and personalized medicine.
Dr. Bartholomew emphasized that the quantum internet is fundamentally different from conventional technology. “We’re trying to zoom in on nature at the level of single atoms and single electrons,” he explained. This unique perspective opens up new possibilities for computation and measurement, enabling faster and more accurate results than current technologies can provide.
In an effort to inspire the next generation of scientists, Dr. Bartholomew recently attended an event hosted by the Sydney Quantum Academy at Xavier Catholic College in North Albury. He encouraged students in the Riverina region to pursue careers in advanced scientific fields, stating, “Just because you’re outside of the major city centres, it doesn’t mean that you can’t be involved in these advanced fields.”
His belief in Australia’s innovative spirit remains strong. “For a lot of history, Australia has been relatively isolated, and when challenges arise, we’ve had to find ways to solve them ourselves,” he said. “There’s a sense of we’re gonna make it work; if that means designing a new way to do it, then so be it!”
Dr. Bartholomew also attributes his success to his faith in the Presbyterian Church, which guides him in his work and interactions. “Service to others is really important,” he stated. “It broadens your field of view from being internally focused to trying to solve problems that will benefit others.”
Looking back on his journey, he reflects on how his relentless curiosity propelled him into the lab. “I kept pushing all of the buttons until I understood how they corresponded with what was happening around me,” he said. Now, he leads a team engaged in groundbreaking research that promises to uncover phenomena never before seen.
As Dr. Bartholomew continues to lead advancements in quantum computing, his story serves as a reminder of the importance of curiosity, community, and service in shaping the future of technology.
