The Australian government is heavily investing in quantum computing, with plans to spend up to $200 million on purchasing a quantum computer from a US company. However, the reality of quantum computing is uncertain, as highlighted by French physicist Xavier Waintal, who warns of weaknesses in current quantum hardware and the need for significant improvements in error rates. While companies like IBM and Google continue to invest in quantum computing, China’s tech giants are abandoning their own quantum computing labs.
The potential applications of quantum computers in fields like biology and chemistry have been touted, but there is no guarantee that they will outperform current computers in these areas. Other scientists are also working on simulating biology and chemistry using artificial intelligence (AI), making significant progress in solving problems that supposedly justify the development of quantum computers.
Therefore, while it is reasonable for the Australian government to invest in quantum computing research, it is important to be realistic about the potential outcomes. Diversifying research funding and exploring other avenues in understanding chemistry and biology at a fundamental level is crucial. The future is unpredictable, and investing in multiple promising technologies is a prudent approach.
