Article Citation - WoS: 14Citation - Scopus: 14Quantum Optics Applications of Hexagonal Boron Nitride Defects(Wiley-v C H verlag Gmbh, 2025) Ateş, Serkan; Cholsuk, Chanaprom; Gale, Angus; Kianinia, Mehran; Pacal, Serkan; Ates, Serkan; Vogl, Tobias; 04.05. Department of Pyhsics; 04. Faculty of Science; 01. Izmir Institute of TechnologyHexagonal boron nitride (hBN) has emerged as a compelling platform for both classical and quantum technologies. In particular, the past decade has witnessed a surge of novel ideas and developments, which may be overwhelming for newcomers to the field. This review provides an overview of the fundamental concepts and key applications of hBN, including quantum sensing, quantum key distribution, quantum computing, and quantum memory. Additionally, critical experimental and theoretical advances that have expanded the capabilities of hBN are highlighted, in a cohesive and accessible manner. The objective is to equip readers with a comprehensive understanding of the diverse applications of hBN, and provide insights into ongoing research efforts.Article Citation - WoS: 22Citation - Scopus: 12Polarization Dynamics of Solid-State Quantum Emitters(Amer Chemical Soc, 2024) Ateş, Serkan; Samaner, Caglar; Cholsuk, Chanaprom; Matthes, Tjorben; Pacal, Serkan; Oyun, Yagiz; Vogl, Tobias; 01. Izmir Institute of Technology; 04.05. Department of Pyhsics; 04. Faculty of ScienceQuantum emitters in solid-state crystals have recently attracted a great deal of attention due to their simple applicability in optical quantum technologies. The polarization of single photons generated by quantum emitters is one of the key parameters that plays a crucial role in various applications, such as quantum computation, which uses the indistinguishability of photons. However, the degree of single-photon polarization is typically quantified using the time-averaged photoluminescence intensity of single emitters, which provides limited information about the dipole properties in solids. In this work, we use single defects in hexagonal boron nitride and nanodiamond as efficient room-temperature single-photon sources to reveal the origin and temporal evolution of the dipole orientation in solid-state quantum emitters. The angles of the excitation and emission dipoles relative to the crystal axes were determined experimentally and then calculated using density functional theory, which resulted in characteristic angles for every specific defect that can be used as an efficient tool for defect identification and understanding their atomic structure. Moreover, the temporal polarization dynamics revealed a strongly modified linear polarization visibility that depends on the excited-state decay time of the individual excitation. This effect can potentially be traced back to the excitation of excess charges in the local crystal environment. Understanding such hidden time-dependent mechanisms can further improve the performance of polarization-sensitive experiments, particularly that for quantum communication with single-photon emitters.
