CASE STUDYDeveloping a distributed network of quantum sensors
WhatIS A DISTRIBUTED NETWORK OF QUANTUM SENSORS?
Quantum sensors use quantum effects to measure physical properties such as time, gravity, magnetic fields, motion, and temperature with exceptional precision.
A distributed quantum sensor network links geographically separated sensing devices via quantum properties such as entanglement, enabling coordinated activity over large areas. By sharing and combining information across the network, these systems can detect subtle changes and provide measurements that are more sensitive and accurate than those from individual sensors, offering a more comprehensive view of complex environments.
Unlike a traditional sensor network where each sensor operates independently, a quantum sensor network uses shared quantum resources, such as entangled quantum states, to coordinate measurements in ways that are not possible with classical networking technologies.
This leads to smaller signals being detected with greater confidence as well as improved resilience and accuracy over large geographical areas, creating a more detailed picture of complex environments.
These capabilities will support entirely new forms of monitoring and detection.
Distributed quantum sensors will benefit sectors that rely on highly accurate measurements.
In environmental monitoring, this could be detecting of seismic activity, groundwater movement and subtle changes to ecosystems.
In infrastructure and energy systems, networks of sensors could identify faults in power grids, pipelines or transport systems earlier than conventional monitoring approaches.
The technology will also support underground mapping and enable accurate navigation where satellite signals are weak or unavailable.
Organisations increasingly depend on timely, accurate information about complex systems. Quantum sensor networks have the potential to improve measurement performance which will support faster decision-making, greater resilience, and more effective management of critical infrastructure and natural resources.
