Summary: In this paper, we propose a scheme to achieve frequency conversion of photons using a hybrid system consisting of a qubit, a resonator cavity, and an optomechanical cavity. The system allows for the conversion of a high-energy photon into a low-energy photon and a phonon, and vice versa, with the qubit acting as an intermediary without changing its state. Additionally, the conversion process can be finely tuned by adjusting the frequency of the qubit or the resonator mode, providing additional control. We analyze the system dynamics and demonstrate two Rabi oscillation behaviors with dissipations. By utilizing state-of-the-art techniques in cavity quantum electrodynamics and optomechanical systems, our proposal can be implemented, leading to the realization of an efficient and controllable quantum light source.

Summary: The study examines the scattering and correlation properties of a two-photon pulse in a four-terminal waveguide system where two one-dimensional waveguides are connected by a Jaynes-Cummings emitter (ICE). It is found that when the width of the incident two-photon Gaussian pulse is much larger than the photon wavelength, the transmission spectra approach that of single photon cases. However, when the pulse width is comparable to the photon wavelength, both transmission and correlation show strong dependence on the pulse width. Resonant scattering and photon interference play significant roles in determining the two-photon correlation in the system.

Summary: This paper investigates quantum noise suppression and phase-sensitive modulation for continuous variable of vacuum and squeezed fields in a hybrid resonant cavity system. Multiple dark windows similar to electromagnetic induction transparency (EIT) are observed in the quantum noise fluctuation curve. The effects of pumping light on both quantum noise suppression and controlling the widths of dark windows are analyzed, and the saturation point of pumping light for nonlinear crystal conversion is obtained. The results show that the noise suppression effect is highly sensitive to the pumping light power, with a degree of noise suppression up to 13.9 dB at a pumping light power of 0.65 & beta;th. Furthermore, a phase-sensitive modulation scheme is demonstrated, which addresses the challenge of multi-channel quantum noise suppression in the quadrature amplitude of squeezed field.

Summary: We propose a novel cavity opto-magno-mechanical hybrid system that can create entanglement among multiple quantum carriers in both the optical and microwave domains. By embedding two Yttrium iron garnet (YIG) spheres in separate microwave cavities, joined by a communal mechanical resonator, we can independently tune the ferromagnetic resonance frequencies and cavity frequencies. Experimental results show achievable entanglement using realistic parameters, and the entanglement is robust against environmental thermal noise due to the mechanical cooling process achieved by the optical cavity. By optimizing the system parameters, the maximum entanglement among different carriers can be achieved, allowing for independent control of entanglement properties in different subsystems and establishing quantum channels with different entanglement properties in one system. This work has promising applications in quantum metrology and quantum information tasks.

The optimal phase angle greatly enhances force sensing. The coexistence of the OPA and Kerr medium improves force sensitivity, while the OPA's nonlinear gain affects the cooling of the membrane.

Summary: This study investigates the manipulation of the quantum phase transition in a well-controlled hybrid quantum system consisting of a Bose-Einstein condensate and a quantum cantilever magnetically coupled. The collective decay is found to play a key role in changing the systemic symmetry and inducing additional quantum phase transitions in this open system. Furthermore, the adiabatic steering of the collective spins into a steady-state spin squeezed state is demonstrated, which may provide a reliable platform for simulating general long-range spin-spin interactions.

Summary: This study investigates the role of grain morphology and distribution in granular aluminium thin films formed into nanowire constrictions using experimental and computational approaches. By treating the granular aluminium film as a network of randomly distributed resistors, the electrical characteristics of the nanowires can be modeled. The electromigration process is shown to be driven by the formation of quantum point contacts between metallic aluminium grains.

Summary: Researchers introduced mobile exciton impurities into a two-dimensional electron gas and conducted experiments on monolayer WS2 using multi-dimensional coherent spectroscopy. They found that at low electron doping densities, the dominant interactions occur between polaron states dressed by the same Fermi sea. Additionally, they discovered a bipolaron bound state with remarkably large binding energy involving excitons in different valleys cooperatively bound to the same electron.

Summary: The prospects of controlling the absorption of cost-effective plasmonic metal nanoparticles Cu and Al using quantum emitters (QEs) are demonstrated semi-analytically. Cu and Au based plasmonic nanoparticles exhibit largely similar exciton-plasmon Fano interaction signatures and similar spectral regions of operation. Cu based nanohybrids show a QE-enhanced maximum absorption that approaches the level of isolated Au MNPs, with decreasing QE-Cu separation, increasing QE dipole element magnitude, and increasing medium permittivity. This makes Cu based exciton-plasmon nanohybrids more economical alternatives for Au MNPs and Au-based nanohybrids in absorption-based applications.

Summary: The development of devices with both superconducting and semiconducting properties is crucial for emerging quantum technologies. This study investigates superconducting nanowires made on a silicon-on-insulator (SOI) platform. The interdiffusion of aluminum and silicon along the entire length of the nanowire is observed, even at temperatures much lower than the Al-Si eutectic temperature. The phase-transformed material matches the predefined device patterns. The superconducting properties of a transformed mesoscopic ring on the SOI platform are also examined, and quantized low-temperature magnetoresistance oscillations in units of the fluxoid, h/2e, are observed.

Summary: In the quest for practical quantum computers, integrated superconducting circuits have emerged as a promising architecture. However, a major challenge is decoherence caused by atomic tunneling defects, which can absorb energy and degrade the qubit's performance. This study demonstrates that tuning these defects away from the qubit resonance using a DC-electric field can improve qubit coherence and increase the qubit's energy relaxation time. The research also explores the implementation of local gate electrodes for simultaneous in situ coherence optimization of individual qubits in superconducting quantum processors.

Summary: Upconversion processes convert multiple low energy photons into one higher energy photon and have potential applications in photovoltaics and biomedicine. This study focuses on two specific mechanisms for photochemical upconversion in solution: triplet-triplet annihilation (TTA) and singlet oxygen mediated energy transfer (SOMET). A kinetic model is developed to explain the different photoluminescence profiles of oxygenated and deoxygenated systems, and the triplet-triplet annihilation rate constant is estimated from the magnetic field response. Design principles to maximize upconversion photoluminescence intensity in oxygenated solution are determined.

Summary: The magnetic field dependence of triplet fusion can be used to determine the parameters of triplet fusion collisions. The reduction of magnetic field effect for perylene triplet fusion is observed as the system moves from quadratic to linear annihilation regimes with an increase in laser power.

Summary: Singlet fission refers to the production of two triplet excitons from one singlet exciton while conserving spin. Although the presence of a spin-2 (quintet) triplet-pair state resulting from singlet fission is well established, the exact mechanism for quintet formation has not been determined, making the design of materials for optimal quintet formation challenging. In this study, the authors propose a mechanism in which fluctuations in inter-triplet exchange coupling drive rapid and efficient quintet formation. They demonstrate that quintet formation is feasible even in the strong-exchange regime, consistent with recent experimental predictions. Evaluating the performance of this quintet formation mechanism under different conformational freedom scenarios, the authors establish a connection between quintet dynamics and material properties of singlet fission molecules.

Summary: This study investigates the photoluminescence anisotropy of CdSe semiconductor nanocrystals experimentally and theoretically. By visualizing emission dipole orientation using defocused wide-field microscopy, it is found that different shaped nanocrystals exhibit different optical properties. The differences in defocused emission patterns of rods and long nanoplatelets are explained by considering valence band structures calculated using multiband effective mass theory and the dielectric effect.

Summary: The role of charge transfer states in multi-exciton mechanisms is difficult to model accurately, but the intermolecular packing has been shown to heavily influence these mechanisms. By studying a gas phase perylene dimer, it was found that displaced geometries yield large charge transfer contributions for singlet fission, while triplet-triplet annihilation charge transfer couplings are weak. Slipping of the dimer cofacial geometry is beneficial to both charge transfer-mediated processes within a wavefunction overlap scheme. The results provide insights into singlet fission and can guide further investigations in this field.

Summary: Charge transport in topological insulators is mainly influenced by helical edge states, which can carry dissipationless current as long as time-reversal symmetry is preserved. However, the presence of magnetic impurities can lead to backscattering and break the time-reversal symmetry. We studied the effects of magnetic impurities on transport properties and observed secondary effects caused by defect-defect interactions.

Summary: Spatially separating electrons of different spins and efficiently generating spin currents are crucial for spintronics devices. In this study, we simulated an InGaAs-based transverse magnetic focusing device and found that the resolution of features in the conductance spectra is affected by the shape, separation and width of the leads, and the number of subbands occupied by the electrons in the leads affects the ratio between the amplitudes of the spin-split peaks in the spectra.
