Questions on starting on photonics quantum computing

Hi @CatalinaAlbornoz ,

Thank you for your detailed answered. I read through the resources that you gave and I cleared much of the misconceptions I had.

I have some questions:

  1. Do the latest GKP qubits only work as qubits and can’t be extended to qudits? I saw a post that support for qudits might be added in the future at Qudits in Pennylane. I have some knowledge on qudits and I am thinking qudits can be useful for encoding high-dimensional data in quantum machine learning.
  2. Also on the same vein as the first question, since the latest devices are GKP qubits, can the systems still be used for continuous variable experiments using MrMustard for example?
  3. Measurement-based quantum computing is interesting! Will the bottleneck be the speed of measurement because there will be a lot of measurement in the computation?
