Indeed the X8 device is from 2019 so it looks small now in 2023
I understand that it is smaller than the current standards, but still having 8 qumodes is still a big deal, as you can’t easily simulate those 8 qumodes in a classical machine. However, it only supports a limited number of Gaussian gates and that is something I wanted to confirm.
It will still be a photonic quantum computer but not CVQC.
So can I expect a qubit-based universal quantum computer to be made soon? (from the different academic talks, it is computation using GKP states, that I heard being developed.) I understand if this is something confidential.
In conclusion, all I can do is wait, given that I can’t simulate circuits any further, isn’t it?
Thank you for the time and insights
