# 1. let's annotate out function to convert it
# to function that can be executed remotely
# using `run_qiskit_remote` decorator

	return Estimator().run([circuit], [obs]).result().values


# 2. Next let's create out serverless object to control
# where our remote function will be executed

# 3. create serverless context

	# 4. let's put some shared objects into remote storage that will be shared among all executions
	obs_ref = put(SparsePauliOp(["ZZ"]))

    # 4. run our function and get back reference to it
    # as now our function it remote one
	function_reference = my_function(circuits[0], obs_ref)

    # 4.1 or we can run N of them in parallel (for all circuits)
	function_references = [my_function(circ, obs_ref) for circ in circuits]

	# 5. to get results back from reference
    # we need to call `get` on function reference
	print("Single execution:", get(function_reference))
	print("N parallel executions:", get(function_references))
