Summary: This study theoretically investigates optomechanically induced transparency in a spinning Kerr-nonlinear resonator. By considering the interplay between the optical Kerr effect and the Sagnac effect, the transparency windows of the signal can be modified in a flexible way compared to a single spinning resonator system. The system exhibits distinct transparency phenomena and fast-to-slow light effects, with a symmetric transparency window appearing by adjusting the rotation-induced Sagnac frequency shift to compensate for the Kerr-induced frequency shift. These findings offer a new approach to explore novel light propagation in optomechanically induced transparency devices in spinning resonators with Kerr nonlinearity.

Summary: The study demonstrates that asymmetry in four-body interactions among KPOs leads to photon number inhomogeneity, which degrades performance. A method is proposed to reduce inhomogeneity by tuning the detunings of KPOs based on their positions, without monitoring their states during adiabatic time evolution.

Summary: Photon-pressure coupling between two superconducting circuits, one of which can be operated as a parametric amplifier, is implemented in this study. The results show an enhancement of the photon-pressure single-photon coupling rate and an increase of the cooperativity by one order of magnitude in the amplifier regime. In addition, intracavity amplification reduces the measurement imprecision of RF signal detection. Surprisingly, RF mode sideband cooling is not only limited to the effective amplifier mode temperature arising from quantum noise amplification, which is interpreted in the context of nonreciprocal heat transfer between the two circuits.

Summary: This paper presents a direct measurement of the loss tangent of insulating materials using a high-quality-factor superconducting niobium resonator, with a focus on a high-resistivity intrinsic silicon wafer. The study reports significant findings on the loss tangent values of silicon at low temperatures and for electric field amplitudes comparable to those in quantum devices, as well as a nonmonotonic trend in the loss tangent with temperature. The research sheds light on the optimization of quantum devices and the understanding of their decoherence channels.

Summary: This paper aims to model nonlinear optical processes within the metatronics paradigm using the concept of optical lumped circuit elements. By adding displacement current sources to these elements, the analysis of nonlinear processes is simplified, leading to the development of nonlinear optical components and devices. The paper investigates second- and third-order nonlinearities in a nanosphere and presents a step-by-step example of modeling a practically realizable LiNbO3 nanorod. The results are compared with full-wave simulations, and the significance of the proposed model is discussed.

Summary: The main aim of this paper is to conduct a detailed study on a high-order nonlinear Schrodinger equation involving nonlinear dispersions and the Kerr effect. Optical solitons, including bright and dark solitons, are derived through the modified Kudryashov method after reducing the governing model describing ultra-short pulses in optical fibers in a one-dimensional domain. The dynamical behavior of these solitons is formally investigated for different sets of parameters, showing that nonlinear dispersions have significant effects on the soliton amplitudes.

Summary: In this study, we theoretically investigate the nonlinear optical phenomena including optical stability state and four-wave mixing process in a hybrid opto-electromechanical system with the cross-Kerr effect. The cross-Kerr interaction and the Coulomb coupling between the optomechanical cavity and the external circuit introduce a tristability behavior of the mean intracavity photon number, which can be electrically controlled by the voltage.

Summary: Researchers predict a set of unusual quantum acoustic phenomena resulting from sound-matter interactions in a fully tunable solid-state platform, and show that using a spatially varying laser drive can lead to unconventional quantum sound-matter interactions by tuning the mechanical band structure. They also demonstrate the emergence of a quasichiral sound-matter interaction with tunable ranges from bidirectional to quasiunidirectional.

Summary: This paper reports high qubit coherence, low cross-talk, and single-qubit gate errors in a superconducting circuit architecture that can be tiled into a two-dimensional lattice of qubits. The architecture integrates an inductively shunted cavity enclosure with non-galvanic out-of-plane control wiring and qubits and resonators fabricated on opposing sides of a substrate. Experimental results demonstrate the feasibility of the design, and simulations predict that the enclosed qubits will maintain a clean electromagnetic environment at arbitrary scale.

Summary: In this study, the DC Kerr effect in plasma-enhanced chemical vapor deposition silicon rich amorphous silicon carbide (a-SiC) is demonstrated. The extracted third order nonlinear susceptibility chi((3)) is found to be more than six times higher than previously reported values in stoichiometric a-SiC, making silicon rich a-SiC a promising candidate for nonlinear photonic applications.

Summary: This work investigates the interaction between a qubit and a nonlinear Kerr-like quantum-harmonic-oscillator cavity field through nonlinear intensity-dependent and one-photon interactions. The analytical solution for the master equation is obtained under certain initial conditions. The dynamics of the phase space Husimi-distribution and its Wehrl-Husimi entropy entanglement/mixedness are explored under various factors, including atom-field detuning, Kerr-like nonlinearity, and atomic spontaneous-emission dissipation. The study finds that the interaction leads to the generation of entanglement and mixedness, and the dynamics of the Husimi-distribution and its Wehrl-Husimi entropy are highly sensitive to different parameters.

Summary: The article introduces the SNZ CZ gate, which achieves fast two-qubit gate operations by maximizing intermediate leakage. The key advantage of SNZ lies in its simplicity of tuning, attributed to the regular structures of leakage and conditional phase as a function of two control parameters that are useful for intermediate-scale applications.
