Super-resolution of two Closely-spaced Electromagnetic Fields via Walsh-Modulated Dynamical Decoupling Spectroscopy
Hao Wu, Grant D. Mitts, Clayton Z. C. Ho +2
Due to quantum fluctuations, non-orthogonal quantum states cannot be distinguished with complete certainty, making their underlying physical parameters difficult to resolve. Tradit…

Nonlinear-enhanced wideband sensing via subharmonic excitation of a quantum harmonic oscillator
Hao Wu, Clayton Z. C. Ho, Grant D. Mitts +2
A key advantage of quantum metrology is the ability to surpass the standard quantum limit~(SQL) for measurement precision through the use of non-classical states. However, there is…
