qadence.draw example plots

Mostly for quick, manual checking of correct plotting output.

from qadence import X, Y, kron
from qadence.draw import display

b = kron(X(0), Y(1))

from qadence import X, Y, chain
from qadence.draw import display

b = chain(X(0), Y(0))

from qadence import X, Y, chain
from qadence.draw import display

b = chain(X(0), Y(1))

from qadence import X, Y, add
from qadence.draw import display

b = add(X(0), Y(1), X(2))

from qadence import CNOT, RX, HamEvo, X, Y, Z, chain, kron

rx = kron(RX(3,0.5), RX(2, "x"))
rx.tag = "rx"
gen = chain(Z(i) for i in range(4))

# `chain` puts things in sequence
block = chain(
    kron(X(0), Y(1), rx),
    CNOT(2,3),
    HamEvo(gen, 10)
)

from qadence import feature_map, hea, chain

block = chain(feature_map(4, reupload_scaling="Tower"), hea(4,2))

from qadence import QuantumModel, QuantumCircuit, total_magnetization, hea

model = QuantumModel(QuantumCircuit(3, hea(3,2)), total_magnetization(3))

from qadence import *

b = chain(SWAP(0,1), SWAP(0,3))

from qadence import *

b = chain(CPHASE(0, 1, 0.5), CPHASE(0, 2, 0.5), CPHASE(0, 3, 0.5))

This section contains examples in pure graphviz that can be used to understand roughly what is done in the actual drawing backend.
