We present a fully quantum model for the excitation of a bound electron basedon the free-electron bound-electron resonant interaction (FEBERI) scheme. Thebound electron is modeled as a quantum two-level system (TLS) at any initialquantum (qubit) state, and the free electron is presented as a pre-shapedquantum electron wavepacket (QEW). In the case that the QEW is short ormodulated at optical frequency, the TLS quantum state may be coherentlycontrolled with multiple modulation-correlated QEWs. For this case, we derivethe transition probability of the TLS due to interaction with a multi-particlebeam based on an analytical approximate solution of the Schrodinger equationthat amounts to using Born's probabilistic interpretation of the quantumelectron wavefunction. We verify the credibility of the analytical model at itsvalidity ranges using a fully quantum density matrix computation procedure. Itis shown that the transition probability can grow quadratically with the numberof correlated QEWs, and theoretically - exhibit full Rabi oscillation. Thestudy indicates a possibility of engineering the quantum state of a TLS byutilizing a beam of shaped QEWs.
