We implemented the Schrödinger equation, which describes the time evolution of a two-qubit superconducting system, on an analog computer. In this work, we decomposed the complex amplitude into real and imaginary parts and mapped the resulting system of first-order differential equations onto an analog computational circuit. We then performed the time evolution of the Hamiltonian corresponding to the CNOT gate on the constructed circuit.
