The collecting of highly precise measurements can enable research developments and technological advancements in numerous fields. In physics, high-precision measurements can unveil new phenomena and experimentally validate theories.
Quantum-enhanced metrology techniques are emerging methods that enable the collection of precise measurements utilizing non-classical states. While these techniques could theoretically outperform classical approaches, reliably manipulating non-classical states to achieve high-precision measurements has so far proved challenging.
Researchers at the International Quantum Academy, Southern University of Science and Technology, and University of Science and Technology of China recently introduced a new approach to realize quantum-enhanced metrology. Their proposed approach, introduced in Nature Physics, was found to enable the efficient generation of large Fock states with up to almost 100 photons.
