cbloq_to_quimb#

Convert a composite bloq into a tensor network.

qualtran.simulation.tensor.cbloq_to_quimb(
    cbloq: qualtran.CompositeBloq,
    friendly_indices: bool = False
) -> qtn.TensorNetwork

This function will call Bloq.my_tensors on each subbloq in the composite bloq to add tensors to a quimb tensor network. This method has no default fallback, so you likely want to call bloq.as_composite_bloq().flatten() to decompose-and-flatten all bloqs down to their smallest form first. The small bloqs that result from a flattening 1) likely already have their my_tensors method implemented; and 2) can enable a more efficient tensor contraction path.

Args

cbloq

The composite bloq.

friendly_indices

If set to True, the outer indices of the tensor network will be renamed from their Qualtran-computer-readable form to human-friendly strings. This may be useful if you plan on manually manipulating the resulting tensor network but will preclude any further processing by Qualtran functions. The indices are named {soq.reg.name}{soq.idx}_{j}{side}, where j is the individual bit index and side is ‘l’ or ‘r’ for left or right, respectively.
