holy_calamity writes "The first computers with a von Neumann architecture, where a processor has access to RAM, appeared in the 1940s. Now the first quantum computing system with a von Neumann design has been made, at University of California Santa Barbara. Their quantum processor made up of two superconducting quantum bits can use a 2-bit "quantum RAM" to save entangled bit values into."

  • Von Neumann arch = Executable code in ram (Score:4, Interesting)

    To be considered a Von Neumann architecture, the program code needs to be stored in the same ram as the working data. That's the whole point of it. Otherwise, it's a Harvard architecture.

    Given that the total ram capacity seems to be 2 bits (though, in all fairness, the bits are qu), it seems implausible that a useful program could fit in it.

    Though I have not actually read TFA, I'd say to be skeptical about this. What they probably meant is "It has RAM." Unfortunately they used the completely wrong term for this.
