Resumé: Two of the main areas of quantum technologies are communication and sensing. In
communication, by exchanging quantum systems and sharing entanglement we have security
and efficiency that cannot be achieved classically. In sensing, using quantum probes allows
for precision and sensitivity beyond any possible measurement based on classical physics.
As we move towards a quantum internet, where quantum devices of different sizes and
applications are connected through classical and quantum channels, it is natural to consider
the possibility of merging the incredible benefits of quantum sensing and communication.
Indeed in an ‘internet of quantum things’ combining security, efficiency with the super
classical measurements, for example ensuring sensing data is secure and trusted, would
appear to suggest much possibility for great advantage.
We imagine a network of sensors, of all different kinds, with different applications, connected
by quantum and classical channels, and we want to push the limits of what can be done, by
incorporating cutting edge quantum cryptographic techniques and ideas. Networking
quantum sensors is already understood to offer many benefits. Entangling sensors allows
sensing global fields or features over a network (such as total or average field strength), with
applications for novel synchronisation of clocks and telescope alignments to name a few.
Clearly any additional security and efficiency is greatly beneficial here. Even without
entangling the sensors themselves, the capacity to delegate sensing, or securely communicate
the results in a trusted, possibly anonymous, way has many promising applications. One
could imagine many sensors deployed across a network (for example of cars, or medical
devices), that wish to securely share sensitive data locally collected.
Previous works looking at combining quantum security with quantum sensing, though
inspiring, have often lacked cryptographic rigor, leaving them open to security loopholes. In
a recent work, we make the first steps to address these issues, developing formal notions
of security for sensing, and provide new, secure, protocols for delegated (two party) quantum
sensing. In this project we will develop a formal framework for secure sensing in networks,
combining rigorous cryptographic techniques with sensing.
Building on recent work of, we
will enable more involved network sensing scenarios (multiparty, multiparameter, various
levels of trust and mistrust), and develop towards near term practical implementations.
- Develop a formal framework for security for networks of quantum sensors
- Develop proposals for proof of principle experiments demonstrating quantum
advantage in networks of sensors
