This lady have no idea what she is talking about.
- im-a-baby 4y agoI believe the point is that quantum computers allow you to manipulate a linear combination of bits, whereas simulating the weather would require non-linear combinations. It's unclear how a QC would help simulate something like that better than a classical computer.
- quantum_mcts 4y agoQuantum algorithms are nonlinear. If someone is saying "quantum mechanics is a linear theory" as a counterargument to anything QC related. Then that person has no idea what they are talking about. Because they likely never cared to learn event the basics of QC.
- raziel2701 4y agoQuantum mechanics is a linear theory. That's not an erroneous statement. Quantum computing and quantum mechanics, not the same thing.
- fauigerzigerk 4y agoI don't think it's quite as simple as that: "New Quantum Algorithms Finally Crack Nonlinear Equations. Two teams found different ways for quantum computers to process nonlinear systems by first disguising them as linear ones." https://www.quantamagazine.org/new-quantum-algorithms-finally-crack-nonlinear-equations-20210105/ https://www.quantamagazine.org/new-quantum-algorithms-finall...
- mikewarot 4y agoI believe that she was using the term "linear" in the computational/signal processing sense, not that of computing. In electronics, in a linear system, you can decompose a complex waveform and analyze its response to each frequency discretely, and when you recompose them, you get a correct answer. In a non-linear system, such as a mixer, no such analysis is possible, you have to consider all of the frequencies, and their levels at the same time. Also consider that most algorithms are founded on a deterministic computational method.
