Add Cirq --> Braket IonQ Gate conversions

[ryanhill1]

IonQ native gates include GPi, GPi2, and MS, see https://ionq.com/docs/getting-started-with-native-gates

We recently added support for converting IonQ gates from Braket $\rightarrow$ Cirq:

qBraid/qbraid/transpiler/cirq_braket/convert_from_braket.py

Lines 182 to 187 in 7a436d8

	if cirq_ionq_ops and isinstance(gate, (braket_gates.GPi, braket_gates.GPi2)):
	phi = gate.angle / (2 * np.pi)
	gate_class = (
	cirq_ionq_ops.GPIGate if isinstance(gate, braket_gates.GPi) else cirq_ionq_ops.GPI2Gate
	)
	return [gate_class(phi=phi).on(*qubits)]

and

qBraid/qbraid/transpiler/cirq_braket/convert_from_braket.py

Lines 287 to 294 in 7a436d8

	if cirq_ionq_ops and isinstance(gate, braket_gates.MS):
	return [
	cirq_ionq_ops.MSGate(
	phi0=gate.angle_1 / (2 * np.pi),
	phi1=gate.angle_2 / (2 * np.pi),
	theta=gate.angle_3 / (2 * np.pi),
	).on(*qubits)
	]

In this issue, we now want to add support for the equivalent conversion(s) linked above, but going from Cirq $\rightarrow$ Braket:

qBraid/qbraid/transpiler/cirq_braket/convert_to_braket.py

Lines 209 to 214 in 7a436d8

	if cirq_ionq_ops and isinstance(
	gate, (cirq_ionq_ops.GPIGate, cirq_ionq_ops.GPI2Gate, cirq_ionq_ops.MSGate)
	):
	raise NotImplementedError(
	"Cirq to Amazon Braket IonQ gate conversions not yet supported."
	)

Hi @ryanhill1, Can I try this issue?

[ryanhill1]

@devilkiller-ag Absolutely, go for it!

[ryanhill1]

Relevant section is now here: (

qBraid/qbraid/transpiler/braket/cirq_to_braket.py

Lines 214 to 216 in aa86a58

	raise NotImplementedError(
	"Cirq to Amazon Braket IonQ gate conversions not yet supported."
	)

)

Thanks @ryanhill1 I will complete this soon.
