there have been no specific timelines or estimates within the transhumanism community regarding when we might be able to trace back and copy the information or memories of long-deceased individuals using quantum computers. It's important to note that the field of transhumanism encompasses a wide range of perspectives and ideas, and opinions may vary among individuals within the community.
Quantum computing is still an area of active research and development, and its full potential is yet to be realized. While quantum computers have shown promise in solving certain types of problems more efficiently than classical computers, such as factoring large numbers, their practical applications are still being explored. Currently, the most advanced quantum computers have a few hundred qubits, and they are primarily used for specific scientific and computational tasks.
The idea of reconstructing memories or information from deceased individuals is highly speculative and would involve significant technological advancements in neuroscience, artificial intelligence, and quantum computing. It is difficult to provide a specific number of qubits required for such a complex task, as the feasibility and requirements of such a process are still largely unknown.
It's worth mentioning that the idea of copying or transferring memories raises numerous ethical, philosophical, and technical questions that extend beyond the scope of scientific and technological advancements. These questions involve considerations of personal identity, consciousness, and the nature of subjective experience.
As research progresses in various fields, including quantum computing, neuroscience, and artificial intelligence, it is possible that new insights and breakthroughs may emerge in the future. However, at the present moment, the ability to trace back and copy the memories of long-deceased individuals using quantum computers remains speculative and largely a topic of science fiction.
