Quantum Chinese Remainder Clock
Ivri Nagar, Alioscia Hamma, Mikel Palmero +3
The Chinese remainder theorem is used in metrology for extending the range of quantum clocks/radar/interferometry, where the phase of a signal is known relative to a set of oscilla…
Butterfly Echo Protocol for Axis-Agnostic Heisenberg-Limited Metrology
Jacob Bringewatt, Leon Zaporski, Matthew Radzihovsky +4
The extreme sensitivity of chaotic systems to external perturbations makes them natural candidates for sensing applications. We propose a single-shot echo-based protocol for estima…
Quantum-amplified global-phase spectroscopy on an optical clock transition
Leon Zaporski, Qi Liu, Gustavo Velez +5
Optical lattice clocks (OLCs) are at the forefront of precision metrology, operating near a standard quantum limit (SQL) set by quantum noise. Harnessing quantum entanglement offer…
Enhancing Dynamic Range of Sub-Quantum-Limit Measurements via Quantum Deamplification
Qi Liu, Ming Xue, Matthew Radzihovsky +4
Balancing high sensitivity with a broad dynamic range is a fundamental challenge in measurement science, as improving one often compromises the other. While traditional quantum met…
