Hi, I am a junior in the realm of Quantum, Just out of curiosity, Is ECR gate a clifford gate ?

This implementation differs to ecr by a -pi/4 global phase. is it generally ok ?

If I am not mistaken this one doesn't have phase difference
qc.h(1)
qc.cx(0, 1)
qc.t(1)
qc.cx(0, 1)
qc.x(0)
qc.cx(0, 1)
qc.tdg(1)
qc.cx(0, 1)
qc.h(1)

I coped from stabilizer
qiskit-aer/src/simulators/stabilizer/stabilizer_state.hpp
Lines 389 to 397 in b706ee1

BaseState::qreg_.append_z(op.qubits[1]); // sdg(1) | |

But it seems it was not correct, ad I get correct circuit by using transpiler
from qiskit import transpile
from qiskit import QuantumCircuit
from qiskit_aer import AerSimulator
sim = AerSimulator(basis_gates = ["h", "cx", "x", "s", "z"])
qc = QuantumCircuit(2)
qc.ecr(0, 1)
qc = transpile(qc,backend=sim,optimization_level=0)
qc.draw('mpl')
I will fix by using this circuit
Great thank you |
* Add support for ECR gate * replace is not to != * fix release note * Fix ecr implementation for stabilizer/extended-stabilizer
* release 0.14.2 * Disable test shot_branching on MacOS (#2143) * remove test_shot_branching * disable sho_branching tests on MacOS * fix test * fix test * format * fix test_shot_branching * fix test_runtime_parameterization * fix tests for the latest Qiskit (#2138) * Remove qiskit aer translation stage (#2142) This commit removes the qiskit aer translation plugin. This was added as a workaround for a Qiskit/qiskit#11351. This has been fixed in Qiskit since 0.45.2 and is no longer necessary. The mechanism by which the workaround worked was unsound in practice as it was mutating the target and also explicitly using private attributes of the Target. This is causing real issues now as it only worked by assuming the target wasn't shared between passmanagers which is never guaranteed. Similarly the reliance on internal private attributes of the Target class will cause issues in the future when the target internals change (see Qiskit/qiskit#12292). This commit opts to remove the plugin in its entirity as it's no longer necessary and actively causing issues with Qiskit 1.1 and transpiling targeting aer backends with >1 circuit. As it's private internal detail there isn't a release note.
