Least Variable Quantum Counting Processes
Bita Olamaei, Florian Meier, Costantino Budroni +2
Counting processes provide a fundamental description of stochastic events ranging from photon detection to clock ticks. A central question is how accurately such events can be time…
Qutrit entanglement and joint multi-parameter estimation in an optical clock platform
Ohad Lib, Shuheng Liu, Maximilian Ammenwerth +7
Quantum metrology harnesses entanglement to improve measurement precision beyond classical limits. While standard protocols rely on two-level qubits to estimate a single parameter,…
The uncertainty geometry of finite-dimensional position and momentum
Dimpi Thakuria, Shuheng Liu, Giuseppe Vitagliano +1
Uncertainty relations are usually stated as bounds on selected combinations of variances, but the full covariance matrix contains substantially richer information about the geometr…
Thermal Entanglement and Out-of-Equilibrium Thermodynamics in 1D Bose gases
Julia Mathé, Nicky Kai Hong Li, Pharnam Bakhshinezhad +1
We investigate entanglement in and out of equilibrium in a one-dimensional Bose gas in its low-energy Bogoliubov regime. In this Gaussian setting, the state is fully characterized…
