Personally I find quantum computers really impressive, and they havent been given its righteous hype.

I know they won't be something everyone has in their house but it will greatly improve some services.

That article talks about a bedside magnetometer device, used to measure the heartbeat of a person. I can't find any reference to quantum computers ๐Ÿ™

I appreciate the conversation, but it does seem like you're dismissing everything to fit with your narrative. Quantum computing is absolutely a new and emerging field, I was just trying to showcase that it's farther than 21 divided by 7. From wikipedia, https://en.m.wikipedia.org/wiki/Magnetocardiography, MCGs are pretty much by definition a quantum sensor. The technical aspects of the paper linked goes in to how their device is different and why it does not require cryogenic cooling.

you're dismissing everything [...]

Not at all. On the contrary, I'd love to learn some more about it. That's why I'm asking all these questions. The thing is, we're talking about something here (quantum computers) and you're saying they have one. And then you go on talking about an entirely different subject, saying MCG is useful and they bought some SQUID sensors... Of course I'm dismissing that. Since it has nothing to do with the conversation we're having?! I don't even disagree. Quantum effects certainly exist. And I bet measuring small magnetic fields is super useful in many applications. But what's that got to do with the question I asked?

Ah, I think I misunderstood the conversation, then. I apologize for that. I was considering quantum sensors and other quantum computer adjacent technologies, I suppose. Not just the classic idea of a quantum computer/showing quantum supremacy.

That's alright. I learned something anyways. Maybe I'm a bit overly cautios with these companies. I mean they even combine two of the buzzwords that attract investors... "AI" and "Quantum"... But I don't know much about the topic. Usually we have some classical signal processing available to handle sensor data. But AI can do things like imaging and finding patterns well. I can see how there might be some synergy between the two fields.
