At present, there are many methods of quantum entanglement of particles with\nan electromagnetic field. Most methods have a low probability of quantum\nentanglement and not an exact theoretical apparatus based on an approximate\nsolution of the Schrodinger equation. There is a need for new methods for\nobtaining quantum-entangled particles and mathematically accurate studies of\nsuch methods. In this paper, a quantum harmonic oscillator (for example, an\nelectron in a magnetic field) interacting with a quantized electromagnetic\nfield is considered. Based on the exact solution of the Schrodinger equation\nfor this system, it is shown that for certain parameters there can be a large\nquantum entanglement between the electron and the electromagnetic field.\nQuantum entanglement is analyzed on the basis of a mathematically exact\nexpression for the Schmidt modes and the Von Neumann entropy.\n
