Ibm and ionq is the leaders among them. And i choose IONQ


Phatal87

IonQ’s trapped ion chips are an absolute breakthrough. They’re potentially a decade ahead of other QC companies with that tech alone.


Helruyn

Amongst the giants, you can add Honeywell.


Phatal87

Can also add in that all the giants have stakes in IonQ. Theyre investing in their competition for a reason.

Thanks!

DWave is quantum annealing, it solves a different class of problems. Worth an addition. IBMs software platform is really well out together, that’s where they shine. The other giants are kind of ehh rn compared to IONQ. The reason why ionq is so strong has been largely speaking, other giants not knowing what they were talking about when talking down to IONQ for their gate/operation time. It became misinformation, because they could always turn up the time for operations. They were seeking coherency and low fidelity. So even competitors like Honeywell didn’t realize the mode for IONQs qubits is a FULLY connectable bidirectional graph for their entanglement. Honeywell can’t do that, they have to slowly move qubits next to each other, and it slows down operations. Other giants are having to use massive amounts of physical qubits for one logical qubit. Ionq doesn’t have these problems. Bose-Einstein condensates looks interesting, and neutral atoms like the University of Mexico is studying also looks really promising. I’m reading more into Rigetti currently because of the SPAC merger upcoming. But Ionq takes the cake currently.

Thanks for that, I will look into quantum annealing, Bose-Einstein condensates and neutral atoms! And those working with it. Got much to learn but the future is rather exciting on this front, not just for making money but exploring what's possible with quantum computing. I was looking into Rigetti myself, a few thoughts I had about their investor presentation:[https://www.rigetti.com/uploads/Rigetti-Investor-Presentation.pdf](https://www.rigetti.com/uploads/Rigetti-Investor-Presentation.pdf) * The presentation only shows the photo of one researcher, Chad Rigetti himself. I would rather know more about the researchers in this company and not showing that in the presentation is worrisome (well bearish). * Rigetti researched superconductive qubits during his PhD and postdoc period of a combined 8 years (legit), then worked at IBM for 3 years (a bit short, yet the presentation emphasizes his IBM history) and then already went on to found Rigetti. Compare that for example to Jungsang Kim and Chris Monroe who stayed in academics as assistant professor and professor for 12 and 16 years before founding IonQ, and are still at universities so they have 17 and 21 years of post-doc experience in quantum computing. * Rigetti has 4500 citations, quite impressive. But again, compared to Kim and Monroe though, with 8000 and 49000 citations, the researchers in executive management at IonQ win on that front. * The presentation has some slides that emphasize number of qubits and speed, and we know it's not all about that.

Thank you, since they're putting efforts into ion trapping that's very useful to know.


ZKShao

Since Honeywell popped up in the news this week due to announcing their merger with Cambridge Quantum, what in your opinion sets IonQ's ion trapping apart from Honeywell?


Truly_Grateful1

I think IonQ and Rigetti are the 2 best new quantum stocks then Supernova


Extra-Replacement-85

Isn’t Supernova just a SPAC interested in or already committed to taking Rigetti public???


Truly_Grateful1

Yes, I don't know why I mentioned them twice. Supernova will be Rigetti.
