“…The deployment of fiber-based quantum networks would benefit from a presence of telecommunications range quantum emitters. While Si vacancy and divacancy in 4H-SiC provide longer operating wavelengths than diamond defects and QDs, emerging SiC color centers, such as the NV [128,129] and the vanadium center [130], are currently explored in the range 1300-1550 nm.…”

Integrated photonics will play a key role in quantum systems as they grow from few-qubit prototypes to tens of thousands of qubits. The underlying optical quantum technologies can only be realized through the integration of these components onto quantum photonic integrated circuits (QPICs) with accompanying electronics. In the last decade, remarkable advances in quantum photonic integration have enabled table-top experiments to be scaled down to prototype chips with improvements in efficiency, robustness, and key performance metrics. These advances have enabled integrated quantum photonic technologies combining up to 650 optical and electrical components onto a single chip that are capable of programmable quantum information processing, chip-to-chip networking, hybrid quantum system integration, and high-speed communications. In this roadmap article, we highlight the status, current and future challenges, and emerging technologies in several key research areas in integrated quantum photonics, including photonic platforms, quantum and classical light sources, quantum frequency conversion, integrated detectors, and applications in computing, communications, and sensing. With advances in materials, photonic design architectures, fabrication and integration processes, packaging, and testing and benchmarking, in the next decade we can expect a transition from single- and few-function prototypes to large-scale integration of multi-functional and reconfigurable devices that will have a transformative impact on quantum information science and engineering.

Pressure is a significant parameter to investigate the properties of matter. The phenomenon of pressure-induced magnetic phase transition has attracted great interest due to its ability to detect superconducting behaviour at high pressures in diamond anvil cell. However, detection of the local sample magnetic properties is a great challenge due to the small sample chamber volume. Recently, in situ pressure-induced phase transition has been detected using optically detected magnetic resonance (ODMR) method of the nitrogen vacancies (NV) centers in diamond. However, the NV centers with four orientation axes and temperature-dependent zero-field-splitting present some difficulty to interpret the observed ODMR spectra. Here, we investigate and characterize the optical and spin properties of the implanted silicon vacancy defects in 4H-SiC, which is single-axis and temperature-independent zero-field-splitting. Using this technique, we observe the magnetic phase transition of a magnetic Nd2Fe14B sample at about 7 GPa. Finally, the critical temperature-pressure phase diagram of the superconductor YBa2Cu3O6.66 is mapped and refined. These experiments pave the way for the silicon vacancy-based quantum sensor being used in situ magnetic detection at high pressures.

“…A good spatial positioning of the color centers is important for better integration with photonic structures, but the implantation and irradiation methods lack such a control. To improve lateral positioning, lithographically patterned resist has been used to implant SiC with NV − centers 131 and silicon vacancies 132 at defined positions. Focused ion beam (FIB) has also been employed to implant silicon vacancies in diamond nanostructures 133 and 4H‐SiC with tens of nanometers of position accuracy 134 .…”

Color centers are versatile systems that generate quantum light, sense magnetic fields and produce spin‐photon entanglement. We review how these properties have pushed the limits of fundamental knowledge in a variety of scientific disciplines, from rejecting local‐realistic theories to sensing superconducting phase transitions. In the light of recent progress in material processing and device fabrication, we identify new opportunities for interdisciplinary fundamental discoveries in physics and geochemistry.
