The aim of this work is to study the strong measurement of a superconducting quantum bit. To do so, we analysed both its operating system and its environment, which means we analysed the electrodynamic circuits the qubits are coupled into. Due to the quantum superposition properties the qubit operates on, we are unable to read its two states at the same time. By realising a strong measurement, we are searching the instant state of this qubit. The talk will be organized as following: First, the different devices used to make the superconducting qubit and the QED system is discussed. Then the circuit energy coupled to the superconducting qubit is determined. Lastly, this energy is used to determine the way to measure the qubit state.
