Quantum Wavemetry via the Mth-Power Unitary of a Mach-Zehnder Interferometer

B. S. Ham

A quantum wavemetry scheme based on the coherence de Broglie wavelength (CBW) is proposed using an M coupled Mach Zehnder interferometer (MZI) architecture to achieve superresoluti…

A quantum-operator analysis of N-fold phase accumulation in coherence de Broglie wavelength interferometry

B. S. Ham

Quantum sensing exploits nonclassical states of light, including multiphoton entangled states and squeezed states, to achieve superresolution and/or super-sensitivity. However, its…

Enhanced interferometric resolution via N-fold intensity-product measurements without sacrificing phase sensitivity

S. Kim, J. Stohr, B. S. Ham

The Fisher information theory sets a fundamental bound on the minimum measurement error achievable from independent and identically distributed (i.i.d.) measurement events. The ass…

Coherence spectroscopy by the Nth power of the measured signal in an interferometer overcoming the diffraction limit

Byoung S. Ham

Coherence spectroscopy has been intensively studied over the last several decades for various applications in science and engineering. The Rayleigh criterion defines the resolution…
