pdft.circuit.is_compact_cp# pdft.circuit.is_compact_cp(tensor, atol=0.15)[source]# True if tensor looks like a compact 2x2 CP gate [[1, 1], [1, e^iφ]]. All four entries should have unit magnitude (within atol). Mirror of upstream src/tebd.jl:124-132 / src/mera.jl:190-198. Parameters: tensor (Array) atol (float) Return type: bool
