Kudos to the entire @KipuQuantum team and our amazing collaborators—stay tuned for more exciting results! @agm668 @pranav_xd @KikeSolanoPhys @AdolfodelCampo7 and all the co-authors.

Simulating quantum critical dynamics isn’t just an exciting research problem—it has huge industrial implications for material design. I’m excited to share our latest work on arXiv: "Digitized counterdiabatic quantum critical dynamics" https://t.co/PUl4p2y3Id

[Narendra Hegade @NarendraHegade]

Even with today’s noisy quantum computers, our results show we’re inching closer to solving problems that classical computers simply can’t handle.

[Narendra Hegade @NarendraHegade]

@MvsCerezo Interesting! I heard a similar debate between Scott and Lukin. Is this recorded and available online?

New hope for quantum optimization? Optimization, as one of the primary applications of quantum computers has a third (or fourth?) life. My colleagues developed an approach that provides an exponential speedup over known classical methods for some problems

@MJBiercuk @dallairedemers Yes, it would be great to combine some of these techniques with better optimization algorithm like digitized counterdiabatic quantum optimization (DCQO), which already shows superior performance than QAOA.

[Narendra Hegade @NarendraHegade]

Error suppression techniques are definitely needed. Most importantly, better algorithms are also required. The CD protocol surely performs better here (as mentioned in the discussion section of the paper). In addition, we have tested it experimentally for even more complex problems at this scale (soon in arXiv).

@PedramRoushan @KikeSolanoPhys @qmisanz @LucasLamata @Google Thanks for your reply 🙏. We will DM you.

[Narendra Hegade @NarendraHegade]

Amazing work by Google and others on digital-analog quantum simulation! The authors surely know Kike @KikeSolanoPhys and his group's @qmisanz @LucasLamata work on DAQS and DAQC, but unfortunately, there's not a single citation/credit

🧵 1/5 Tired of variational quantum algorithms like QAOA due to trainability issues on noisy quantum computers? Check out our new work—a purely quantum approach to tackle combinatorial optimization problems! Featuring experimental results with 100 qubits! https://t.co/kSptUytNbI

🧵 4/5 BF-DCQO also achieves two orders of magnitude improvement in ground-state success probability and a 1.3x better approximation ratio than QAOA for the problem sizes studied, showcasing its potential in outperforming standard variational quantum optimization algorithms.
