> 1kb of state It's not though? If we were actually storing the parameters describing the state we'd need 8x10^300 bytes = 8x10^288 Pb (assuming each "continuous parameter" is stored as a double precision float). I do think the author exaggerates the difficulty though. The impossibility of even storing a complicated quantum state on a classical computer just shows how different the world is from a classical computer. The world is quantum. The state space of the world cannot be stored on or manipulated by a classical computer. However, the authors point does show that if we build a quantum computer you will not be able to place it in every possible state (like you can with a block of memory in a classical computer). The space of states in a qc is just too large. That's very different from computer systems we're used to.

Yes, yes. qubits & bits. One must think of QC state space on the order of θ(2^2^N) compared to CC θ(2^N) where N is qubits and bits respectively. IBM's at the 400 qubit mark, and claims to be on-track to deliver 1k within a year. If this were to happen, it'd be like going from the Gemini Guidance Computer to a 386 in 1 year. This means HFT platform$ will be able to use more near-real-time simulation capabilities to gamify the markets to capture greater tranches of total capitalization. I don't see this trend ever declining except when wandering into increasingly-frequent longtail, LTCM-like collapses whenever externalities of the real world catch up to the so-called "efficiencies" of an under-regulated casino masquerading as a bazaar. https://newsroom.ibm.com/2022-11-09-IBM-Unveils-400-Qubit-Plus-Quantum-Processor-and-Next-Generation-IBM-Quantum-System-Two https://newsroom.ibm.com/2022-11-09-IBM-Unveils-400-Qubit-Pl...
