In order to meet the needs of modern people for the acquisition of intangible cultural heritage information, the authors propose a research method that combines 3D scanning and virtual reality technology. Taking the production process of Xiuyu as an example, using Unity3D virtual reality technology combined with a digital platform, 3D modeling of Xiuyu is carried out, so that people can view the intangible cultural heritage information intuitively. The experimental results show that after using this method, more than 60% of more than 1000 people surveyed in the questionnaire want to experience intangible cultural heritage. In a survey of visualization platforms conducted at the same time, 90% of users are willing to combine jade carving technology with 3D scanning virtual reality technology. Conclusion. 3D scanning and virtual reality technology can further promote the process of inheritance and dissemination of intangible cultural heritage, accelerate the cultivation of intangible cultural heritage talents through the visualization platform, and promote the sustainable development of intangible cultural heritage, in order to better pass down the life memory and cultural genes of our ancient nation.

“…We had previously developed a superconductor memory cell that could be reconfigured by applying external control currents and read out by inputting an SFQ clock. 23,24) For this memory cell, highspeed nondestructive read-out at frequencies beyond 50 GHz was possible through SFQ read-out. However, its reconfiguration speed was less because of the use of external control currents.…”

“…However, its reconfiguration speed was less because of the use of external control currents. 23) Nevertheless, this memory cell is suitable for building large-scale FPGAs based on SFQ circuits, because high-speed reconfiguration of the LUT is not required in FPGA applications. We also demonstrated the operation of superconductor LUTs composed of our proposed 4-bit and 64-bit memory cell arrays.…”

“…We also demonstrated the operation of superconductor LUTs composed of our proposed 4-bit and 64-bit memory cell arrays. 23,24) However, for building a large-scale LUT, in addition to advanced circuit-fabrication process, reduction in the footprint of the memory cell used in the LUT is also necessary. In a previous study, we used a non-destructive read-out flip-flop (NDRO) with interface circuits, called magnetically coupled DC/SFQ converter (MC-DC/SFQ), as the memory cell.…”

In this study, we demonstrate a novel method for the reconfiguration of a nondestructively readable memory cell for superconductor integrated circuits. The proposed reconfiguration method involves the direct injection of flux quantum to the storage loop of the memory cell, which has been achieved using interface circuits in the previous studies. By applying this method, the footprint of the superconductor memory cell can be reduced by half. We experimentally demonstrate the proof-of-concept of the investigated reconfiguration method. We expect that the memory cell reconfigured using the proposed method will be suitable for building large-scale lookup tables using superconductor circuits.
