Quantum limits to center-of-mass measurements
We discuss the issue of measuring the mean position center of mass of a group of bosonic or fermionic quantum particles, including particle number fluctuations. We introduce a standard quantum limit for these measurements at ultralow temperatures, and discuss this limit in the context of both photons and ultracold atoms. In the case of non-interacting harmonically trapped fermions, we present e...
متن کاملConservation laws, uncertainty relations, and quantum limits of measurements.
The uncertainty relation between the noise operator and the conserved quantity leads to a bound on the accuracy of general measurements. The bound extends the assertion by Wigner, Araki, and Yanase that conservation laws limit the accuracy of "repeatable," or "nondisturbing," measurements to general measurements, and improves the one previously obtained by Yanase for spin measurements. The boun...
متن کاملQuantum limits for measurements on macroscopic bodies: A decoherence analysis.
We consider in this paper the quantum limits for measurements on macroscopic bodies which are obtained in a novel way employing the concept of decoherence coming from an analysis of the quantum mechanics of dissipative systems. Two cases are analysed, the free mass and the harmonic oscillator, and for both systems we compare our approach with previous treatments of such limits. 03.65.Bz , 04.60...
متن کاملQuantum limits to dynamical evolution
How fast can a quantum system evolve in time, given a certain amount of energy? If the system is composed of a number of subsystems, is entanglement a useful resource in speeding up the dynamical evolution? To answer the first of these two questions, one typically defines some characteristic time of the dynamics and studies its connections with the energy resources of the initial state of the s...
متن کاملOnline Estimation of Ship’s Mass and Center of Mass Using Inertial Measurements
A ship’s roll dynamics is sensitive to the mass and mass distribution. Changes in these physical properties might introduce unpredictable behavior of the ship and a worst-case scenario is that the ship will capsize. In this paper, a recently proposed approach for online estimation of mass and center of mass is validated using experimental data. The experiments were performed using a scale model...
