What is the current behavior?

Currently, some fake simulators throw a NoiseError exception when running an empty quantum circuit (initialized and measured).

qiskit_aer.noise.noiseerror.NoiseError: 'Invalid T_2 relaxation time parameter: T_2 greater than 2 * T_1.'

Steps to reproduce the problem

Run the following program:

from qiskit.circuit import QuantumCircuit
from qiskit import transpile
from qiskit_ibm_runtime.fake_provider import FakeSherbrooke, FakeArmonkV2, FakeAuckland, FakeBelemV2
from qiskit_aer import AerSimulator


qc = QuantumCircuit(1)
qc.measure_all()

backend = FakeSherbrooke()

transpiled_qc = transpile(qc, backend=backend, scheduling_method='asap')
job = backend.run(transpiled_qc)
print(job.result().get_counts())

However, running the same circuit on the real quantum computer or AerSimulator will output the measurement result successfully.

from qiskit.circuit import QuantumCircuit
from qiskit import transpile
from qiskit_ibm_runtime import QiskitRuntimeService
from qiskit_aer import AerSimulator


qc = QuantumCircuit(1)
qc.measure_all()

service = QiskitRuntimeService()
backend = service.backend("ibm_sherbrooke")
backend_sim = AerSimulator.from_backend(backend) # Both backend and backend_sim can run successfully. 

transpiled_qc = transpile(qc, backend=backend, scheduling_method='asap')
job1 = backend.run(transpiled_qc)
print(job1.result().get_counts())
job2 = backend_sim.run(transpiled_qc)
print(job2.result().get_counts())

What is the expected behavior?

The behavior should be consistent across both fake and real backends.
