Description
We present a scheme for the design of quantum control protocols based on shortcuts to adiabaticity. To fight decoherence, the adiabatic dynamics is accelerated. Introducing high-frequency modulations in the control Hamiltonian we mimic a time-dependent counterdiabatic correction. Applications are presented for the high-fidelity realization of quantum state transfers and quantum gates based on effective counterdiabatic driving, in platforms ranging from superconducting circuits to Rydberg atoms [1]. We sketch as well related ideas to control many-body interactions [2] and to counteract evolution errors by compensating terms in the Hamiltonian.
