Quantum control by fast driving — •Sandro Wimberger — Department of Mathematical, Physical and Computer Sciences, Parma University — INFN, Sezione Milano-Bicocca, Parma group

We present a scheme for the systematic design of quantum control protocols based on shortcuts to adiabaticity. To fight decoherence, the adiabatic dynamics is accelerated by introducing high-frequency modulations in the control Hamiltonian, which mimic a time-dependent counterdiabatic correction. We present several applications 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 briefly sketch as well related ideas to control many-body interactions [2] and evolution errors by compensating terms in the Hamiltonian [3].
