Electrical Control of Nuclear Spin Qubits: Important Step For Quantum Computing 42

Taco Cowboy writes: "Using a spin cascade in a single-molecule magnet, scientists at Karlsruhe Institute of Technology and their French partners have demonstrated that a single nuclear spin can be realized in a purely electric manner, rather than through the use of magnetic fields (abstract). For their experiments, the researchers used a nuclear spin-qubit transistor that consists of a single-molecule magnet connected to three electrodes (source, drain, and gate). The single-molecule magnet is a TbPc2 molecule — a single metal ion of terbium that is enclosed by organic phthalocyanine molecules of carbon, nitrogen, and hydrogen atoms. The gap between the electric field and the spin is bridged by the so-called hyperfine-Stark effect that transforms the electric field into a local magnetic field. This quantum mechanical process can be transferred to all nuclear spin systems and, hence, opens up entirely novel perspectives for integrating quantum effects in nuclear spins into electronic circuits"

  • I read it, but it all just made me feel dizzy!

      As I write this, the parent comment is the only one visible by default, nearly an hour after this submission was posted. Yet it's totally useless.

      Meanwhile, there are several good threads of discussion about the actual topic involving Anonymous Coward commenters, yet they're not visible by default.

      It's no wonder Slashdot is on its way out. Total crap, like the parent comment, is visible, while the actual discussion is not. It takes effort to show the useful content.

      If it's any consolation, at least there's

      • So why are you hiding AC comments by default? And why are you posting as such? I thought it was long understood that a lot of the best comments are posted AC, even if a lot of dreck gets posted that way as well.

        Though frankly, I routinely browse at -1 and I'm still not seeing much in the way of decent discussion on this topic.

        And incidentally, does anyone know why some comments still vanish entirely? Do they get downmodded to -2 and thence irretrievable oblivion or what? It's really annoying to encounter

  • can we **please** stop calling this tech "quantum computing"?

    it's factually inaccurate as it does not use quantum non-locality but two independent things that only act as entangled

    the application they are developing it for is cryptography

    "quantum cryptography" still has "quantum" in still sounds just as cool as quantum computing and its much more precise
