Spectrally enhanced gravitational redshift signals in photonic interferometry
Jerzy Paczos, Piotr T. Grochowski, Natalia Bruno +3
Quantum mechanics and general relativity are remarkably successful, yet their joint predictions remain beyond direct experimental reach. Photonic interferometers operating in a gra…
To Cool, or Not to Cool? Displacement Sensing with Hot Quantum States
Piotr T. Grochowski
Quantum-enhanced displacement sensing with bosonic systems is typically formulated assuming that the oscillator is cooled close to its ground state before nonclassical probe prepar…
Quantum Non-Gaussian State Preparation of Levitated Particles via Time-Dependent Control of Weakly Nonharmonic Hybrid Potentials
Piotr T. Grochowski, Oriol Romero-Isart
Levitated high-mass quantum systems provide access to unprecedented regimes in both fundamental science and technological applications. However, deterministic generation and manipu…
Distributed Phase-Insensitive Displacement Sensing
Piotr T. Grochowski, Matteo Fadel, Radim Filip
Distributed quantum sensing leverages quantum correlations among multiple sensors to enhance the precision of parameter estimation beyond classical limits. Most existing approaches…
A passive atomtronics filter for Fermi gases
Jun Hao Hue, Martin-Isbjörn Trappe, Piotr T. Grochowski +2
We design an atomtronic filter device that spatially separates the components of a two-component Fermi gas with repulsive contact interactions in a two-dimensional geometry. With t…
Optimal Phase-Insensitive Force Sensing with Non-Gaussian States
Piotr T. Grochowski, Radim Filip
Quantum metrology enables sensitivity to approach the limits set by fundamental physical laws. Even a single continuous mode offers enhanced precision, with the improvement scaling…
