AI Article Synopsis
- The study explores the phase space structure and statistical properties of photon added cat states, highlighting how photon addition alters interference patterns in the Wigner function.
- Photon addition results in a shift that can act as an error detection mechanism and interchanges the maximum and minimum points of phase space tiles, indicating orthogonality.
- Additionally, it reveals that adding photons to a Yurke-Stoler state transitions it from Poissonian to sub-Poissonian statistics, suggesting applications in reducing quantum noise.
Article Abstract
The phase space structure and statistics of the photon added cat state are studied in the state's general form. Photon addition leads to a phase shift at the origin in the observed phase space interference of the Wigner function, which may serve as an error syndrome detector. The maxima and minima of the sub-Planck tiles in the phase space of the kitten state are interchanged after photon addition, leading to their orthogonality. Interestingly, photon addition to the Yurke-Stoler state characterized by Poissonian statistics leads to a sub-Poissonian distribution, which may find potential use in quantum noise reduction.

Controlling the Mott transition through strain engineering is crucial for advancing the development of memristive and neuromorphic computing devices. Yet, Mott insulators are heterogeneous due to intrinsic phase boundaries and extrinsic defects, posing significant challenges to fully understanding the impact of microscopic distortions on the local Mott transition. Here, using a synchrotron-based scanning X-ray nanoprobe, we studied the real-space structural heterogeneity during the structural phase transition in a VO thin film.

In the present work, we propose an experimental setup to investigate the effect of atmospheric turbulence on user-defined beams. The user-defined beams were formed by writing reconfigurable patterns on a spatial light modulator, allowing the impact of atmospheric turbulence to be investigated simultaneously and in real time. The programmable controllability provides several flexibilities to the system, such as the ability to create different beam types simultaneously, control the separation between different beams, compensate for aberrations, and easily switch between different beam types.

Three-component crown ether phase change materials are characterized by a structural phase change in response to external stimuli such as temperature and electric or magnetic fields, resulting in significant changes in physical properties. In this work, we designed and synthesized two novel host-guest crown ether molecules [(PTFMA)(15-crown-5)ClO] (1) and [(PTFMA)(15-crown-5)PF] (2), through the reaction of -trifluoromethylaniline (PTFMA) with 15-crown-5 in perchloric acid or hexafluorophosphoric acid aqueous solution. Compound 1 undergoes a structural change from the non-centrosymmetric space group (2) to the centrosymmetric space group (2/) with increasing temperature.

Polaritons are central to the development of nanophotonics, as they provide mechanisms for manipulating light at the nanoscale. A key advancement has been the demonstration of polariton canalization in which the energy flow is directed along a single direction. An intriguing case is the canalization of ray polaritons, characterized by an enhanced density of optical states.

Of the few weberite-type Na-ion cathodes explored to date, NaFeF exhibits the best performance, with capacities up to 184 mAh/g and energy densities up to 550 Wh/kg reported for this material. However, the development of robust structure-property relationships for this material is complicated by its tendency to form as a mixture of metastable polymorphs, and transform to a lower-energy Na FeF perovskite compound during electrochemical cycling. Our first-principles-guided exploration of Fe-based weberite solid solutions with redox-inactive Mg and Al predicts an enhanced thermodynamic stability of NaMg Fe F as the Mg content is increased, and the = 0.
