- Regarding quantum computers: In reality, quantum computers have not yet reached a level where new research can be conducted. At best, they can attempt to calculate things already processed by supercomputers. The 127-qubit device is still very rudimentary, similar to a toy. Although IBM is continually developing updated versions, the installation at Yonsei University might eventually feature a better model. Personally, there are doubts about whether meaningful calculations can be performed using it. Using a supercomputer for calculations might be faster after the installation of Supercomputer 6 (meaning practical use of quantum computers is currently challenging).
- Resistance Measurement: Instruments for resistance measurements can measure resistance limits of around 10^-8 to 10^-11 ohms. This is the so-called “measured resistance.” This measured resistance needs to be converted into resistivity, considering a standard thickness of 1 cm, resulting in ohm cm. Even if the instrument’s resistance limit is -11 ohms, the converted resistivity may reach -13 (with a thickness of 0.01 cm). Li Shipei mentioned resistance, and due to it being a thin film, the thickness could be on the nanometer level. Therefore, even if the measured value does not reach the equipment’s limit, the calculated resistivity could still be around -13.
- Discrepancy in Resistance Value: A participant who attended the event yesterday commented on the resistance testing video, stating that they personally witnessed a measured value of -13 (not calculated). However, there is a discrepancy as the photos on the presentation slides showed -10. The complete superconductivity standard is -22, and Keithley’s high-sensitivity instrument noise RMS limit is around -11. Although a measured value of -13 is visible, it might be within the device’s noise range, making it uncertain if it’s noise or a genuine measurement. A value around -11 seems more accurate. Achieving -22 would require using the National Institute of Standards and Technology’s Hall resistance measurement formula for recognition.
- Validity of Li Shipei’s Videos: A netizen who attended the conference questioned whether the person truly understood Li Shipei’s videos, particularly the credibility of the zero-resistance tests. The netizen, being from a science and engineering background, emphasized familiarity with units and questioned the authenticity of the zero-resistance claim. They affirmed their understanding of units, stating that unless the data in the video is forged, there’s no doubt that it is indeed zero resistance.
