back to article Intel: Our fabs can mass produce silicon qubit devices

Intel and QuTech claim to have created the first silicon qubits for quantum logic gates to be made using the same manufacturing facilities that Intel employs to mass produce its processor chips. The demonstration is described by the pair as a crucial step towards scaling to the thousands of qubits that are required for …

    "manufacture qubits at scale"

    So, entangled atoms can be engraved in a silicon process.

    Who knew ?

    I would have thought that you needed to do something to achieve entanglement. If they have actually found a way to entangle atoms in an engraving process, well congratulations.

    Somehow, I am doubtful though.

      Supposition "A" - that the scientists and engineers are clueless morons.

      Or supposition "B" - you don't "entangle atoms in an engraving process" but build machinery that can produce entangled electrons as needed.

      A clue as to which might be true is that entangled ensembles are short-lived and easily disrupted by the environment, even at a few kelvin. Another is the paper itself which includes lines like "A [Quantum Dot] device is similar to a transistor, taken to the limit where the gate above the channel controls the flow of electrons one at a time."

      This link might provide some insight into what Intel is talking about -- https://en.wikipedia.org/wiki/Spin_qubit_quantum_computer Or not.

      WARNING -- The article deteriorates fairly quickly into physics-speak. If you, like me, have only the vaguest idea what a Hamiltonian operator is, you'll probably find the latter part of the article utterly incomprehensible. But the initial part does seem to indicate that one can probably do quantum computing using single electrons manipulated within structures that are within the capability of modern semiconductor fabrication technology.

    Every advert on Quantum Computing appears mostly as a game of B.S. Bingo. Show me the product instead of just the box, and then maybe I'll be interested. Of course the product may, or may not exist inside the box; and the act of looking may change the behaviour of it.

      "... the act of looking may change the behaviour of it."

      So... hardware finally catching up to software, then?

    Intel, how about you pull your finger out of your arse and move on from 10nm already. We don't want 125W CPU's in our laptops. 2 hours real life battery life doing real work doesn't really cut it in 2022 any more.

    And while you're at it, how about shipping some of those 12th gen laptop chips. The laptops were supposed to be available in March. We're 2/3s of the way into April and apart from a couple of Dell's, there's nowt.

      Yeah well move to ARM or AMD if you must stick with x86. Why this x86 horse refuses to die is beyond belief.
