Overview
Background
Professor Bowen is Director of the Australian Research Council Centre of Excellence in Quantum Biotechnology, and leads the Quantum Optics Laboratory at UQ. He is recognised both nationally and internationally for research at the interface of quantum science and nanotechnology; including bioimaging, biotechnology, nanophotonics, nanomechanics, quantum optomechanics and photonic/quantum sensing. He is a Fellow of the Australian Institute of Physics.
Professor Bowen's research spans from the very fundamental, e.g. how does quantum physics transition into our everyday world at large scales?, to applied, e.g. developing next generation sensors for medical diagnostics and navigation. To pursue this research, his lab works in close partnership with industry and uses state-of-the-art facilities for nanofabrication, nanoanalysis, precision optical measurement and deep cryogenic refrigeration available in-house or on campus at UQ.
Professor Bowen has supervised more than thirty postgraduate students, who have been recognised with prizes such as Fulbright Scholarships, an Australian Youth Science Ambassadorship, a Springer PhD theses prize, the Queensland nomination for the Australian Institute of Physics Bragg Medal, the Australian Optical Society Postgraduate Student Prize and UQ Graduate of the Year. He regularly has projects available, both for postgraduate students and for postdoctoral researchers. Please check his website, above, or contact him directly for details (w.bowen@uq.edu.au).

Research interests
-
Quantum biotechnology
Prof Bowen works on the applications of quantum technologies in the life sciences and biotechnology: quantum-enabled medical imaging systems and medical diagnostics, better tools for the development of drugs and proteomics, and better methods to see biological structures and dynamics in cells and proteins. His laboratory has developed the first quantum-enhanced light microscopes to better image cells, and new proteomic tools to observe the dynamics of proteins at unprecedented speed. They are developing new magnetic sensing technology to detect biomagnetic fields from the brain, heart and muscle.
-
Quantum measurement and control
Prof Bowen works on furthering our understanding of measurements at the quantum level, and how these measurements can be used to control quantum devices. His interests in quantum measurement range from the very fundamental to applications for quantum technologies. He particularly focuses on quantum optomechanics, studying how light interacts with nanofabicated mechanical devices. Fundamental questions include: how does quantum decoherence occur?, how can quantum mechanics be reconciled with the classical physics at everyday size scales?, and what limits does quantum mechanics place on measurement precision? Quantum technological applications include quantum computing components such as interfaces to map quantum information between light and computing nodes and mechanical quantum memories.
-
Quantum and precision sensing
Prof Bowen develops quantum and precision sensing technologies for applications in ares ranging from biomedicine to aerospace, resources and defence. His laboratory have pioneered optomechanical sensing, for instance developing the first optomechanical magnetometers and ultrasound sensors. These sensors have significantly advanced the state-of-the-art in precision silicon-chip based sensing. Prof Bowen's laboratory is working with industry partners to translate the sensors they develop into practical applications such as improved navigation on drones, geological surveying, and through-Earth communications, and to provide new capabilities in biomedical imaging.
-
Superfluid physics and devices
Superfluids are a quantum state of matter that exists at very low temperature. They exhibit a macroscopic quantum wave function, and counter-intuitive behaviour such as flow without resistance. Superfluid helium is the only liquid superfluid. Prof Bowen's laboratory has led the applications of nanophotonics (light confined to very small scales on a silicon chip) to understand and control superfluid helium. This has allowed them to demonstrate new capabilities, such as laser cooling of a liquid, and new understanding, such as about the turbulent behaviour of quantum vortices. It also allows them to build liquid quantum technologies, where the quantum nature of superfluid helium promise capabilities far beyond what is possible with other technologies. For instance, accelerometers with millions of times better precision than can otherwise be achieved.
-
Nanomechanical computing
Semiconductor computers have been transformational for humanity, offering unprecedented computational power. This has been driven, in large part, by Moore's Law - that the number of transistors that can be packed into an integrated circuit doubles every two years. However, Moore's Law cannot continue indefinitely, and is already reaching its limits. Moreover, the energy consumption of semiconductor computing is now a large fraction of total global energy use. Prof Bowen's laboratory is working to address this challenge, developing alternative computer architectures based on nano mechanical devices: computing using the flow of vibrations rather than electrons. This offers the possibility to reduce energy consumption by a factor of 10,000. It also allows intrinsically radiation hard computing, promising to improve the robustness of the world satellite communications systems to solar flares and other radiation phenomena.
Research impacts
Professor Bowen's laboratory has made important contributions, including demonstrating that quantum techniques can enhance the performance of biological microscopes; developing a new class of state-of-the-art magnetometers that allow magnetic resonance imaging (MRI) to be miniaturised to chip-scale with prospective applications in medical/chemical diagnostics, geological surveying and other areas; showing that laser cooling techniques can be applied to superfluid helium, an important medium for generation-after-next sensors in navigation; and reaching the quantum limit to performance in single molecule sensors.
Professor Bowen is highly motivated to translate progress in quantum technologies into real-world applications across health, energy, resources, medical diagnostics and other areas. Recently, for example, he led the establishment of the Queensland Quantum Decarbonisation Alliance, a collaboration of 27 partners across academia, government and industry to apply quantum technologies towards reaching net zero.
