    "abstract": "In a direct two-level qubit system, when the Rabi frequency is comparable to\nthe resonance frequency, the rotating wave approximation is not appropriate. In\nthis case, the Rabi oscillation is accompanied by another oscillation at twice\nthe frequency of the driving field, the so called Bloch-Siegert oscillation\n(BSO), which depends on the initial phase of the driving field. This\noscillation may restrict the precise rotation of a qubit made of direct\ntwo-level system. Here, we show that in case of an effectively two-level lambda\nsystem, the BSO is inherently negligible, implying a greater precision for\nrotation of a qubit made of such a lambda system when compared to a direct\ntwo-level qubit in a strong driving field.",
