Qudits instructions

[GiggleLiu]

Measuring Qudits

julia> using Yao

julia> measure(product_state(dit"012;3"); nshots=3)
3-element Vector{BitBasis.DitStr64{3, 3}}:
 012 ₍₃₎
 012 ₍₃₎
 012 ₍₃₎

Dit string Indexing

Now you can play with operators indexing and propagation.

julia> using Yao

julia> h = EasyBuild.heisenberg(60);

julia> cleanup(h[:,cleanup(h[:,BitStr{60}(234)])]) |> length
22

julia> @time cleanup(h[:,cleanup(h[:,BitStr{60}(234)])]);
  0.017032 seconds (169.35 k allocations: 4.729 MiB)

julia> @btime $h[BitStr{60}(235),BitStr{60}(234)]
  161.038 μs (1213 allocations: 57.03 KiB)
