Apply as_sweep for SqrtCZGauge

[babacry]

Example usage:

exec parameterized_circuit, sweeps = self.gauge_transformer.as_sweep(input_circuit, N=5)

with input_circuit:

0: ───H───@───────────────H───M───
          │
1: ───────@^0.5───@───────H───M───
                  │
2: ───────────────@^0.5───H───M───

output parameterized circuit is:

0: ───H───PhXZ(a=a0,x=x0,z=z0)───@──────PhXZ(a=a2,x=x2,z=z2)────────────────────────────────────────────────────────H───M───
                                 │
1: ───────PhXZ(a=a1,x=x1,z=z1)───@^s0───PhXZ(a=a3,x=x3,z=z3)───PhXZ(a=a4,x=x4,z=z4)───@──────PhXZ(a=a6,x=x6,z=z6)───H───M───
                                                                                      │
2: ────────────────────────────────────────────────────────────PhXZ(a=a5,x=x5,z=z5)───@^s1───PhXZ(a=a7,x=x7,z=z7)───H───M───

It looks like you committed a lot of files that you didn't intend to.

[babacry]

That is intended.

There are 2 commits in this,

• the first commit apply as_sweep for SqrtCZGauge.
• the second commit cleanup the support_sweep parameter as all the gauges will by default support sweep.

[eliottrosenberg]

Regarding the second point, do you then need to specify somewhere that the sycamore gauge does not support sweeps yet? (https://github.com/quantumlib/Cirq/blob/main/cirq-google/cirq_google/transformers/sycamore_gauge.py)

[babacry]

Oh, good point! as_sweep is already supported for sycamore gauge. We don't need to add extra code /comments here to support sycamore gauge.

[NoureldinYosri]

this is great but lets allow some flexiblity when parameterizing two qubit gates

[NoureldinYosri]

lets allow for some flexibility and make the signature deal with lists

Callable[[ConstantGauge, Sequence[sympy.Symbol]], Sequence[Tuple[ops.Gate, Union[float, int]]]]
