Keywords:Single-electron devices, Security, spin qubit

We propose an application of semiconductor spin qubits to a security technology. We use the variation of Coulomb diamonds as ID (Quantum Physically Unclonable Function (QPUF)). We use image processing software to identify Coulomb diamonds between different devices .
