Tracking spatiotemporal quantum interference in a double-well potential by femtosecond pulse-pair excitation: a theoretical study

, height of the barrier separating the wells and interpulse phase-locking frequency, on these oscillations are also explored. The localisation of population in either the left well or the right well as a function of interpulse delay is examined and shown to be controlled by chirping of the pulses. Further, we simulate the differential Shannon entropy as a function of time, replicating the wavepacket dynamics. Finally, we show strategies of quantum control and establish a connection between WPI in a double-well and qubits. We also extend our study to the asymmetric double-well potential to shed light on dynamics in real physical systems. Therefore, our study underscores the importance of WPI in molecular systems, having prospective applications in quantum computation and quantum information.
