Quantum-enhanced gyroscopes for navigation
Professor Tim Spiller at the University of Leeds is investigating quantum-enhanced gyroscopes for navigation, writes Steve Bush in UK plc reveals quantum 2.0 science, having visited the National Physical Laboratory.
First simulations indicate they could approach the Heisenberg’s uncertainty limits.
In a quantum gyroscope, ultra cold atoms are held in an asymmetric trap of magnetic and electric fields. When the trap is rotated it imparts a superposition on the cold atoms where they now exist in two states – rotating and static – simultaneously. This non-classical quantum set up is highly sensitive to any additional rotation.
Spiller has mapped out the whole measurement process from the beginning to the end to calculate realistic performance estimates.
Long term, the aim will be to build accurate gyroscopes on semiconductor chips.Tags: gyroscopes, National Physical Laboratory., Professor Tim Spiller, quantum gyroscope, university of leeds
