Utilities

multi_measurement(qv_list[, shots, backend])	This functions facilitates the measurement of multiple QuantumVariables at the same time.
gate_wrap(*args[, permeability, is_qfree, ...])	Decorator to bundle up the quantum instructions of a function into a single gate object.
custom_control(func)	The custom_control decorator allows to specify the controlled version of the decorated function.
lifted(*args[, verify])	Shorthand for gate_wrap(permability = "args", is_qfree = True).
redirect_qfunction(function_to_redirect)	Decorator to turn a function returning a QuantumVariable into an in-place function.
as_hamiltonian(hamiltonian)	Decorator that recieves a regular Python function (returning a float) and returns a function of QuantumVariables, applying phases based on the function's output.
lock(qubits)	Locks a list of qubits, implying an error will be raised if the user tries to perform any operation involving these qubits.
unlock(qubits)	Reverses the effect of "lock".
perm_lock(qubits)	Locks a list of qubits such that only permeable gates can be executed on these qubits.
perm_unlock(qubits)	Reverses the effect of "perm_lock".
t_depth_indicator(op, epsilon)	This function returns the T-depth of an Operation object.
cnot_depth_indicator(op)	This function returns the CNOT-depth of an Operation object.
inpl_adder_test(inpl_adder)	This function runs tests on a desired inplace addition function.
