Turned up some issues along the way.

… energy shift. First attempt (with Claude) to fix the issue. But this brought up another issue, where eigenvalue computation based on H versus U is inconsistent, meaning we're not comparing the same eigenvalues. This was documented by Claude in the included Markdown file.

For time evolution, we need to distinguish between

  • form of the "energy"
    • energy
    • phase (energy multiplied by a quantity proportional to the time)
    • unitary eigenvalue (always magnitude one, but the complex angle corresponds to the phase)
  • shift
    • shifted energy
    • true energy

What about controlled time evolution?

For phase estimation, we need to check what any of this analysis even means
