So in Conculusion : This code wil use CPU+GPU speeds to create a quantum circuit with grover itterations correspend to the btc_address you wanna attack with almost instant speed surley after Transpiling the full Quantum-Circuit into the quantum machine and if there is no pending jobs the progress will be about 2 sec into 1 minute only dpend on how bigger is the num_shots ( wich is how many times the program will shots The qubits inside the circuit
you can get the number easly by caclutation the square root of N where N is the total number of possibilites/Totalrange of the search Keyspace. and than if you succesed created that big nubmer of grover ittertaion fully
the next step it transpiling the circuit into the QPU-Backend wich is also limited for most of ibm-QPUs to certain number and than The QPU will use QFT to bruteforce through the circuit using all the 4 values of ( num_qubits , num_iterrations , target_state and Finlay uses an extra 1 ancilla qubits for Ancillarity to reduce the Quantum Errors Results to get only the most frequents results counts retrived from QPU .
and if you know about how i made it --> The credits is for this ''oracles'' that can make you include some operations inside The QuantumCircuit.
