I try to contribute to things getting better, with sourced information, OC and polite rational skepticism.
Disagreeing with a point ≠ supporting the opposite side, I support rationality.
Let’s discuss to make things better sustainably.
Always happy to question our beliefs.

  • The abstract of the scientific article

    In the relentless pursuit of quantum computational advantage, we present a significant advancement with the development of Zuchongzhi 3.0. This superconducting quantum computer prototype, comprising 105 qubits, achieves high operational fidelities, with single-qubit gates, two-qubit gates, and readout fidelity at 99.90%, 99.62%, and 99.13%, respectively. Our experiments with an 83-qubit, 32-cycle random circuit sampling on the Zuchongzhi 3.0 highlight its superior performance, achieving 1×106 samples in just a few hundred seconds. This task is estimated to be infeasible on the most powerful classical supercomputers, Frontier, which would require approximately 5.9×109  yr to replicate the task. This leap in processing power places the classical simulation cost 6 orders of magnitude beyond Google’s SYC-67 and SYC-70 experiments [Morvan et al., Nature 634, 328 (2024)], firmly establishing a new benchmark in quantum computational advantage. Our work not only advances the frontiers of quantum computing but also lays the groundwork for a new era where quantum processors play an essential role in tackling sophisticated real-world challenges. https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.134.090601

    Random circuit sampling is a problem designed to showcase quantum computing strength. Random circuit sampling is the simulation of the outcome of many randomly generated quantum circuits. So, having a computer based on quantum phenomenon, such as superposition and entanglement, is obviously a big help, as opposed to having to imperfectly simulate this on a classical computer. So much that classical super computer cannot simulate this problem in a reasonable human time anymore. They call this “quantum superiority”.
    It’s like giving a math problem to a math professor and a philosophy professor, and then demonstrating how much better the math professor was at solving this problem.
    But it’s a good benchmark to compare quantum computers between them.

    Overall, it’s still useless to the average server or gamer.







  • I think when people feel like things are going downward (quality of life, economy, local security, international security, ecological crisis etc.), tend to regress towards a conservative reflex. They want to protect what they have, by extension, they don’t want things to change out of fear of losing what they have, or they attribute the loss of what they had to unrelated change (I lost my job because of immigration).
    I think it requires good quality education and information to go past this conservative reflex and understand that accepting some constrains (regulations, taxes) may make society better for everyone.
    It also means that manipulating education and information can prevent that and encourage people to take the natural conservative slope. I think “evil” people have found a powerful tool to do that with the mass adoption of social media that they can buy and manipulate.

    I see two big solutions, either falling so low that humanism bounces back out of terror of what happened like after WW2. Or managing to implement systems that will prevent nefarious manipulation of information and instead promote humanism.
