😢 Thanks u bro... finally some one talking about quantum computing in this level

Quantum computing is so small that it can't be seen, that's why only some are talking about it 😂. Lol. Hope quantum computer data should be this small to avoid being hacked/stolen.

You mentioned that measurement based quantum computing can be done fault tolerantly. Does that require mid-circuit decisions on what measurements to make or is it all post processing? If mid-circuit communication with a classical computer is needed, it is a challenge to store photonic qubits long enough?

Hi! Thanks for these great questions. I'll do my best, but if there's someone who knows better than me out there please intervene! In measurement based quantum computing (and its fault tolerant version), when you do the measurement, you need to have the measurement results from previous rounds to determine which basis to measure. So mid-circuit decisions are definitely needed. I think post processing (or probabilistically succeeding?) is more for the stage of generating the large entangled state than the computation stage. The challenge you mention (storing photonic qubits long enough) is actually related to the photon loss mentioned in the paper (and this video). So yes, it'd be great if classical computation/communication time is not the bottleneck for requiring longer storage time. With finding better materials, etc. (as mentioned in this paper) there seems to be ways to improve the loss and be able to handle longer storage time.

@@mingyukang6734 Thanks for the informative video. Are photons fungible or do some photons demonstrate higher tendencies (regardless of known or unknown reasons) to entangle than others?

@@mingyukang6734 Thanks, is there a formal proof of the fungibility of photos? Is there even a miniscule chance that photons may not be homogenuously fungible even if their attributes are identical? I'm just wondering if the assumption of fungibility could be one of the reasons for the error rates that are experienced.
