Quantum Diamond
Diamond NV centers are excellent qubits, enabling magnetic-field, electric-field, and temperature measurement and quantum information processing. The company describes itself as China's first quantum-grade diamond producer, offering electronic-grade material, high-concentration NV ensembles, and two-dimensional ensembles, with custom concentration, size, and shapes. High-concentration ensembles measure magnetic fields, electric fields, and current precisely and are available in varied custom sizes and concentrations. Single NV centers have good room-temperature coherence and single-photon emission for precision measurement, communication, computing, basic research, and algorithm implementation. Electronic-grade diamond has very low impurities, [N]<5 ppb and [B]<1 ppb, suiting single centers and radiation detection. Xianduan Crystal developed high-quality, extremely low-background-fluorescence material after years of research. NV centers in micro/nanodiamonds improve spatial resolution and fiber coupling for simpler instruments. High-concentration ensembles are available in multiple particle sizes and concentrations.
