Sensors, enabling observations across vast spatial, spectral, and temporal scales, are major data generators for information technology (IT). Processing, storing, and communicating this ever-growing amount of data pose challenges for the current IT i

The field of quantum metrology seeks to apply quantum techniques and/or resources to classical sensing approaches with the goal of enhancing the precision in the estimation of a parameter beyond what can be achieved with classical resources. Theoreti

Periodic arrays of nanoholes perforated in metallic thin films interact strongly with light and produce large electromagnetic near-field enhancements in their vicinity. As a result, the optical response of these systems is very

We encode information in the distribution of the far-field correlations of bright twin beams. Using a perturbative approach to calculate the expected spatial correlations, we increase the fidelity between the simulated and experimental results.

Parameter estimation at the fundamental limit given by the quantum Cramér-Rao bound is an important milestone for quantum metrology. Here, we present experiments that saturate this bound for transmission estimation with a macroscopic quantum state.

The spatial degree of freedom of quantum states of light can offer new possibilities for imaging and sensing applications, such as enhanced optical resolution, noiseless image amplification, and enhanced beam positioning. In order to take full advant

The minimum resolvable signal in sensing and metrology platforms that rely on optical readout fields is increasingly constrained by the standard quantum limit, which is determined by the sum of pho...

The minimum possible uncertainty when estimating a parameter, in this case transmission, is bounded by the quantum Cramer-Rao bound (QCRB). This bound is independent of the measurement technique and as result can be used to quantify how close a measu
Quantum states of light can enable sensing configurations with sensitivities beyond the shot-noise limit (SNL). In order to better take advantage of available quantum resources and obtain the maximum possible sensitivity, it is necessary to determine
