Space for improvement in the quantum metrology of time and frequency
Throughout history, humankind has developed systems of measurement to quantify things as varied as the distribution of crops, the distance between cities and the weight of tradable commodities. When it comes to time, we have progressed from sundials to hourglasses, pendulums and atomic clocks. Accurate measurements and comparisons rely on standardised units – we must know quite precisely what corresponds to one unit of measurement to derive the rest. Quantum metrology is based on quanta or packets of energy, the standardised unit, and the use of quantum effects such as entanglement to extend precision beyond that possible with classical approaches. The EU-funded STORMYTUNE project is developing a new quantum way to measure time and frequency based on spatial separations rather than classical time-based phases. The development of novel devices will demonstrate the concept’s ability to surpass the performance of classical methods.
