Pulse Shaping Cuts STIRAP Transfer Errors by Orders of Magnitude

Researchers at Sofia University have achieved a significant improvement in the efficiency of multistate stimulated Raman adiabatic passage (STIRAP) by implementing a novel pulse-shaping method. The work demonstrates a reduction in population transfer error by several orders of magnitude when compared to standard Gaussian pulses, a result achieved without requiring additional control fields. Julian K. Dimitrov and Nikolay V. Vitanov at the Center for Quantum Technologies applied this approach via numerical simulations to five-, seven-, and nine-state chains formed by magnetic sublevels driven by right- and left-circularly polarized pulses. The team found that these chains are generally more favorable…
