Quantum Inevitability

Have you guys seen the latest breakthrough in Quantum Computing?

Check it out: The speediest quantum operation yet.

Did you take a peek at the article, or did you move on to more seductive news? I hope you took a chance for science. There will be more Donald Trump tweets to read about tomorrow.

If you did read the article, it probably had you feeling one of three ways: excited (like me), scared (also like me), or completely bored.

Do I understand the article? Nope. Not really. And that’s even after the subject matter has been dumbed down for my consumption.

Physicists don’t even know what is happening in the quantum realm. But they are smart enough to figure out some of the rules. And upon those rules, they have built their layers of abstraction. Their decades of hard work have culminated into the two-qubit quantum gate.

Are you familiar with a qubit? It’s a quantum bit. Unlike the on-or-off-only “bit” your laptop or cellphone uses to process and store information, the qubit has an extra “state”. This state is the weird, confusing part about quantum physics. It is not a defined state, but a probability of possible states. The possibilities of harnessing their processing power could give us computers that are magnitudes faster than what we have now.

And now that these qubits have been packaged into a silicon logic gate like today’s computer processors, I feel like its only a matter of time before something mind-blowing happens (If it hasn’t already in some secret facility).

The scientists involved in the known projects tell us to be patient; that useful applications are years away. We will see.

By the way, China just teleported a particle 500 kilometres away. To a satellite.

    1. Nice. Was it about time travelling aliens? A buddy was telling me about a book like that but I forgot the title.

      It is always hard for me to wrap my head around any of it no matter how “dumbed down”, but I keep trying because… like you said, it is fascinating stuff.

  1. OK. I wasn’t scared, until I read your last line.

    Thanks for defining qubit. The article didn’t, which made things difficult.

    I think I sort of understand what’s being said, but I also can’t believe it. I understand this article to be saying that the team was able to observe electrons spinning around the atom in real time (how???), and then to stop individual electrons at any point in their spin, without destroying the atom or the space/time continuum.

    I could be wrong. Probably am, given that quantum stuff is unpicturable (right?) and we don’t even really know what it is (right?).

    1. Good for you for diving into this stuff.

      I am not sure how they are measuring the “spin”. I don’t even think spin is actual spinning, but a name they have assigned to a property they can measure.

      A physicist would probably laugh at my explanation. We might not have the math and physics backgrounds to understand what they are fiddling with but I believe it is the stuff that makes a literal quantum leap forward possible.

      Like most things, I guess time will tell.

      1. Yes, that would make more sense than what I thought.

        Question. If they manage to develop quantum computers at scale, would these things even be dependent upon traditional power? Like, would they need electricity to function? And if not, does that mean that once they make one, they’ve created an almost infinitely powerful computer that can’t be turned off?
