Abstract
We present rapid and robust protocols for STIRAP and quantum logic gates. Our
gates are based on geometric phases acquired by instantaneous eigenstates of a
slowly accelerating inertial Hamiltonian. To begin, we establish the criteria
for inertial evolution and subsequently engineer pulse shapes that fulfill
these conditions. These tailored pulses are then used to optimize geometric
logic gates. We analyze a realization of our protocols with $^{87}$Rb atoms,
resulting in gate fidelity that approaches the current state-of-the-art, with
marked improvements in robustness.
