Australia's place in the world
The United States has the highest research impact for quantum sensors, and has the top 2 institutes internationally. Australia is ranked 16th for research impact, and the Australian National University is ranked 45th internationally. Australia is ranked 3rd for venture capital (VC) investment for quantum sensors, behind the United States and the United Kingdom. China has the highest number of patents in this area, ahead of the United States (2nd) and Japan (3rd).
Behind the United States and China, Japan also has considerable strengths in this area and is ranked 3rd for research impact and patents, and 4th for VC investment. There are 3 Japanese institutes in the international top 10 institutions.
Opportunities and risks
Quantum sensors present a wealth of opportunities for Australia. By exploiting the inherent sensitivity of quantum states, quantum sensors can detect changes in the physical environment faster, more precisely and/or with higher sensitivity. The CSIRO report, Growing Australia’s Quantum Technology Industry, forecast that Australia could generate $940 million in revenue if it could capture 5% of the estimated addressable market for quantum-enhanced sensors in 2040. An Australian quantum sensing industry could create 2,900 new jobs under this scenario and contribute to indirect job creation via flow-on demand and productivity gains.
Civil engineers and geologists can use quantum sensor-based gravity gradiometers to detect buried or hidden structures or cavities many times faster than using ground penetrating radar. By using atomic properties as the reference, quantum sensors can remain accurate indefinitely without costly and/or time consuming recalibration. This reliability can enable high-precision navigation in environments where external reference signals like GPS are too weak or otherwise unreliable. Quantum sensors can also be used to detect structures and changes inside the human body, much like an MRI machine but with a wider range of applications.
Quantum sensors also pose risks to Australia, particularly our military platforms. For example, adversaries could potentially use quantum sensors to more readily and more accurately detect military aircraft and marine vessels. Australia needs to understand the capabilities and limitations of quantum sensors, to enable adjustment of strategies and tactics, or to potentially devise new countermeasures and protections for our armed forces.
Research impact (RI)
The United States has the highest research impact, with Australia ranked 16th. Total volume of published research has been increasing at around 4% p.a. over the 5 year period 2016–2020, with 39% of research involving international collaboration.
- USA - 15802
- China - 7989
- Japan - 6023
- Germany - 5656
- UK - 2910
- Australia - 836
The research impact provides an indication of the productivity of a country or institution. Here, productivity was assumed to be represented by the volume of publications (i.e. scholarly output) as an indicator of the resources & facilities, and the level of interest in the publications as an indicator of quality.
Australia is ranked 3rd for VC investment for quantum sensors, which is led by the United States. Investment in this area has been growing at 50% per annum since 2016.
