Quantum Uncertainty and Entropy
Giovanni Chesi, Lorenzo Maccone
We review the plethora of uncertainty relations that appear in quantum mechanics and their nuances. We present both foundational applications, e.g. in understanding and defining co…
Time correlations from steady-state expectation values
Wojciech Górecki, Wojciech Górecki, Simone Felicetti +2
Recovering properties of correlation functions is typically challenging. On the one hand, experimentally, it requires measurements with a temporal resolution finer than the system'…
Interplay between time and energy in bosonic noisy quantum metrology
Wojciech Górecki, Francesco Albarelli, Simone Felicetti +2
Quantum entanglement and coherence often allow for protocols that outperform classical ones in estimating a system's parameter. When using infinite-dimensional probes (such as a bo…
Quantum-enhanced dark matter detection with in-cavity control: mitigating the Rayleigh curse
Haowei Shi, Anthony J. Brady, Wojciech Górecki +3
The nature of dark matter is a fundamental puzzle in modern physics. A major approach of searching for dark matter relies on detecting feeble noise in microwave cavities. However,…
