Summary: This article proposes an architecture for linear-optical quantum computing based on three-photon GHZ states. By combining topological quantum error-correction codes with three-qubit repetition codes, the architecture can tolerate a remarkably high photon-loss rate. Compared to other schemes, this architecture is resource efficient and can be further improved if larger GHZ states are available. The article suggests that this scheme brings scalable photonic quantum computing a step closer to reality, with its significant enhancement in the photon-loss threshold and recent progress in generating multiphoton entanglement.

Summary: Defining metrics for near-term quantum computing processors is crucial for reporting progress, comparing platforms, identifying bottlenecks, and designing a technology roadmap. This letter presents a framework to map physical imperfections in measurement-based quantum computing (MBQC) processes to logical errors, enabling the use of well-known metrics to characterize MBQC. The framework is showcased by studying a continuous-variable cluster state for photonic quantum computing and calculating the quantum volume based on GKP squeezing and photon transmission rate.

Summary: This study demonstrates wavelength-scale, low-threshold, vortex and anti-vortex nanolasers with topological charges in an optical cavity formed by a topological disclination. The optical vortices of the lasing modes are clearly identified through the measurement results. This simple design procedure paves the way towards the development of next-generation optical communication systems.

Summary: A novel semiconductor chip is proposed for generating photonic dimers, a quantum photonic state, and a measurement scheme to validate their existence is discussed. The design utilizes InAs epitaxial quantum dot structures coupled to weak laser pulses via a chiral nanophotonic waveguide, with the performance analyzed as a function of quantum dot misalignment. It is expected that excitation efficiency greater than 50% can still be achieved as long as the quantum dot is positioned in the lower half of the chiral waveguide.

Summary: This study presents a trace formulation for solving the emission problems of spatially incoherent light sources. The formulation can be efficiently combined with inverse design for topology optimization. By utilizing the low-rank structure of emission problems, the formulation generalizes to a continuum of emission directions. The study provides several examples of incoherent-emission topology optimization and discusses potential applications in Raman sensing and cathodoluminescence.

Summary: Mechanical oscillators with high quality factors and coupling to various fields can be ideal sensors. Coupling a flexural mode of a suspended carbon nanotube to charge states of a double quantum dot can induce anharmonicity for a mechanical quantum bit, but requires ultrastrong coupling regime. The system shows potential for reduced dephasing and applications in quantum computation and sensing.

Summary: Integrated photonics is an important platform for quantum entanglement, with applications in communication, information processing, and metrology. However, existing quantum light sources have limitations that hinder their scalability and practical use. In this study, we demonstrate a fully integrated quantum light source that overcomes these challenges through the integration of a laser cavity, a tunable noise suppression filter, and a nonlinear microring. The source shows high performance parameters and creates high-dimensional entangled quantum states, making it suitable for practical applications.
