Phase estimation in spontaneous nonlinear interferometry for enhanced quantum imaging
Jonas L. Moos, Cristofero Oglialoro, Enno Giese +1
Bicolor quantum imaging can reach, in principle, phase supersensitivity approaching the Heisenberg limit using squeezed light from high-gain parametric down-conversion, but establi…
Parameter Estimation from Amplitude Collapse in Correlated Matter-Wave Interference
Daniel Derr, Dominik Pfeiffer, Ludwig Lind +2
Operating matter-wave interferometers as quantum detectors for fundamental physics or inertial sensors with unprecedented accuracies relies on noise rejection, often implemented by…
Below-shot-noise capacity in phase estimation using nonlinear interferometers
Cristofero Oglialoro, Gerard J. Machado, Felix Farsch +7
Over the past decade, several schemes for imaging and sensing based on nonlinear interferometers have been proposed and demonstrated experimentally. These interferometers exhibit t…
An epsilon-near-zero-based nonlinear platform for ultrafast re-writable holography
M. Zahirul Alam, Robert Fickler, Yiyu Zhou +3
We re-examine real-time holography for all-optical structuring of light and optical computation using a contemporary material: a subwavelength-thick, spatially unstructured film of…
Entanglement and Its Verification: A Tutorial on Classical and Quantum Correlations
Enno Giese
Entanglement, a defining property of quantum mechanics in which two physical subsystems cannot be seen as independent entities, challenges our everyday experience and classical int…
