Quantum Computing's Limitations Highlighted Amid Media Hype

According to Odaily, Shaw recently expressed on the X platform that there is a significant gap between the actual progress of quantum computing and the media portrayal and public perception. Despite advancements in the field, quantum computers are unlikely to achieve their purported capabilities within the next 40 to 50 years. Even with the optimal application of Grover's algorithm, hash functions like SHA-256 can only reduce the search space from 2 to the power of 256 to 2 to the power of 128, which remains physically unbreakable. Shaw emphasized that the most advanced quantum computers currently cannot factorize the number 21 into 3 and 7 without prior knowledge of the result. To compromise Bitcoin, a quantum computer would need to perform repeated calculations on the live network within minutes, a leap far beyond the progress from 1950s computers to modern server clusters. Modern cryptography was designed with future computational growth in mind, and current fears or hype surrounding quantum computing lack factual basis.
