Summary: In this paper, dissipative phase transition (DPT) near critical point in a system with two-photon driving and nonlinear dissipations is studied. By incorporating quantum fluctuations into the mean-field theory, new effects in the system's steady-state are observed. The presence of quantum fluctuations leads to power-law dependence of the anomalous average at the phase transition point, and also affects the critical point renormalization and the existence of a two-photon pump threshold.

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: A scheme for quantum storage of single photons using EIT in a low-finesse optical cavity is presented, assisted by state-selected spontaneous atomic emission. Quantum interference between the cavity input-output channel and state-selected atomic spontaneous emission results in strong absorption of single photons with unknown arrival time and pulse shapes. This phenomenon is discussed for its application in photon counting using stored light.

Summary: This study theoretically investigates the single-photon scattering properties in a one-dimensional waveguide coupled to a cavity and a two-level atom. Two cases are considered: when the waveguide is coupled to the cavity-emitter and when it is coupled to both a cavity and a two-level atom. In our system, the phase of the emitter-cavity-waveguide coupling strength acts as a sensitive controller, allowing for control of perfect transmission, perfect reflection, and adjustment of transmission spectrum.

Summary: Quantum information processing is gaining popularity in machine learning and image processing, especially in the field of quantum convolution. This study focuses on angle-based quantum convolution, which imitates classical convolution by optimizing variational quantum circuits. The proposed method requires the same number of qubits as the filter size, and the generated circuits contain N x N x 4 quantum gates and N x N x 3 trainable parameters.

Summary: This study evaluates the performance of bosons, fermions, and qubits as quantum reservoirs by measuring linear and nonlinear memory capacity. It is found that fermions provide the best reservoir due to their intrinsic nonlocal properties. Moreover, a tailored input injection strategy enhances the computational power of bosonic quantum reservoir computing compared to qubits and fermions.

Summary: This paper presents a practical approach to quantum theory using current simulation and processing technology. The proposed project allows the creation of an exploration graph, where all possible states for an initial qubit configuration are produced based on user-selected gates. Each node in the graph provides information such as applied gates, cost, quantum circuit representation, and state amplitudes. The project serves as a processing platform that enables users to visualize and explore diverse solutions for different quantum problems. Furthermore, potential applications in other research fields, including a new interpretation of a quantum neural network and a hybrid processing chain for finding specific state conditions, are discussed.
