Harnessing the center-of-mass excitations in quantum metrology

  title={Harnessing the center-of-mass excitations in quantum metrology},
  author={Karol Gietka},
In quantum metrology, one typically creates correlations among atoms or photons to enhance measurement precision. Here, we show how one can use other excitations to perform quantum-enhanced measurements on the example of center-of-mass excitations of a spin-orbit coupled Bose-Einstein condensate and a Coulomb crystal. We also present a method to simulate a homodyne detection of center-of-mass excitations in these systems, which is required for optimal estimation.

Entanglement in fermion systems and quantum metrology
Entanglement in fermion many-body systems is studied using a generalized definition of separability based on partitions of the set of observables, rather than on particle tensor products. In this
Quantum metrology with nonclassical states of atomic ensembles
Quantum technologies exploit entanglement to revolutionize computing, measurements, and communications. This has stimulated the research in different areas of physics to engineer and manipulate
Critical Quantum Metrology with a Finite-Component Quantum Phase Transition.
It is shown that, in spite of the critical slowing down, critical quantum optical probes can achieve a quantum-enhanced time scaling of the sensitivity in frequency-estimation protocols.
Quantum metrology.
It is proved that the typical quantum precision enhancement is of the order of the square root of the number of times the system is sampled, and it is pointed out the different strategies that permit one to attain this bound.
Photonic quantum metrology
This work discusses the current experimental and theoretical challenges, and the open questions towards implementation of photonic quantum sensors with quantum-enhanced performances in the presence of noise, in the research area of multiparameter quantum metrology, where multiple parameters have to be estimated at the same time.
Understanding and Improving Critical Metrology. Quenching Superradiant Light-Matter Systems Beyond the Critical Point
We carefully examine critical metrology and present an improved critical quantum metrology protocol which relies on quenching a system exhibiting a superradiant quantum phase transition beyond its
Squeezing of Quantum Noise of Motion in a Micromechanical Resonator.
This work prepares a nearly macroscopic moving body, realized as a micromechanical resonator, in a squeezed quantum state, and obtains squeezing of one quadrature amplitude 1.1±0.4  dB below the standard quantum limit, thus achieving a long-standing goal of obtaining motional squeezing in a macroscopy object.
Entanglement, nonlinear dynamics, and the heisenberg limit.
The analysis singles out the class of entangled states which are useful to overcome classical phase sensitivity in metrology and sensors and studies the creation of useful entangled states by the nonlinear dynamical evolution of two decoupled Bose-Einstein condensates or trapped ions.
Photonic realization of the quantum Rabi model.
We realize a photonic analog simulator of the quantum Rabi model, based on light transport in femtosecond-laser-written waveguide superlattices, which provides an experimentally accessible test bed
Optimal phase measurements with pure Gaussian states
We analyze the Heisenberg limit on phase estimation for Gaussian states. In the analysis, no reference to a phase operator is made. We prove that the squeezed vacuum state is the most sensitive for a
