Summary: Hybrid integration provides an important avenue for incorporating atom-like solid-state single-photon emitters into photonic platforms. Hexagonal boron nitride (hBN) is particularly interesting quantum emitter for hybrid integration, as it provides a route for room-temperature quantum photonic technologies. Despite recent progress, a deterministic, site-controlled process for integrating hBN emitters in photonic waveguides remains elusive.

Summary: Since linear-optical two-photon gates are inherently probabilistic, measurement-based implementations are particularly well suited for photonic platforms. However, generating the necessary photonic resource state, called a graph state, is still a challenge. This study proposes near-deterministic solutions for generating graph states using current quantum emitter capabilities, combining it with all-photonic fusion gates.

Summary: Scaling up quantum hardware is crucial for realizing the full potential of quantum technology, with photonics offering a modular approach and solid-state quantum emitters enabling key quantum functionalities. The use of integrated photonics foundry technology can lead to small-footprint quantum processors, while deterministic photon-emitter interfaces could pave the way for resource-efficient hardware architectures in quantum communication and computing applications.

Summary: This study introduces a protocol for deterministically generating multidimensional photonic cluster states using a single atom-cavity system and time-delay feedback, where the dimensionality of the cluster state increases linearly with the number of time-delay feedbacks. The method is valuable for simulating matrix product states and projected entangled pair states, and for analyzing experimental imperfections and logical errors. Through numerical simulation, an optimal atom-cavity cooperativity for fidelity of the generated states is observed, challenging the prevailing assumption that higher-cooperativity systems are inherently better for photonic applications.

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: We introduce a programmable photonic integrated circuit (PIC) capable of high-speed and high-fidelity reconfigurable optical connections for optically-heralded entanglement among target qubits. The PIC's N x N Mach-Zehnder mesh (MZM) can generate optical connectivity on up to 8 inputs and demonstrated optical connections between 16 independent pairwise mode couplings with high fidelity. This programmable PIC platform enables the fast and scalable optical switching technology necessary for network-based quantum information processors.

Summary: Freely propagating optical quantum states with negative Wigner functions are deterministically generated with a 60% photon generation efficiency by mapping the internal state of an intracavity Rydberg superatom onto an optical qubit. The evolution from quadrature squeezing to Wigner negativity is observed by changing the qubit rotation angle. This experiment overcomes major roadblocks in optical quantum engineering.

Summary: Single-emitter plasmonic patch antennas are room-temperature deterministic single-photon sources that exhibit highly accelerated and directed single-photon emission. The deterministic room-temperature in situ optical lithography protocol is used to position the plasmonic structure nondestructively on any selected single-emitter with 3D nanoscale control. The presented antenna induces a 1000-fold effective increase in the absorption cross-section and shows nonlinearly enhanced emission under high pumping.

Summary: In this work, we propose an innovative approach that simplifies the preparation of non-Gaussian states compared to previous proposals by utilizing modern quantum photonics tools. Our protocol relies on a single projective measurement along a mode that partially overlaps with all the input modes, enabling parallel execution and showcasing its straightforward feasibility. We demonstrate that our protocol can generate high-quality and high-amplitude Schrodinger cat states as well as more complex states such as error-correcting codes.

Summary: This study shows that with coherent photon conversion, flying-qubit gates can be constructed that are insensitive to wave shapes and temporal and spectral correlations between photons. These gates are important for scalable computation as they allow for the processing of both unentangled and entangled photonic wave packets effectively.

Summary: Researchers have proposed and demonstrated a method for implementing multi-mode measurement-induced quantum gates in a large two-dimensional optical cluster state through optical measurements. They have successfully executed a small quantum circuit on a three-mode input state and believe that fault-tolerant universal quantum computing is possible with this platform by improving cluster-state entanglement and supplying states with specific encoding.

Summary: Fe-doped MoS2/WSe2 heterostructures grown via chemical vapor deposition can produce high-purity chiral single photons without the need for external magnetic fields. This ability to manipulate quantum states and transform linear polarized photons into high-purity chiral photons on-chip enables integration of nonreciprocal devices in quantum photonics.
