SEMINAR: Quantum control by fast driving

Quantum control by fast driving

Professor Sandro Wimberger

University of Parma, Italy

‍

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 counter diabatic correction. We present several applications for the high-fidelity realization of quantum state transfers and quantum gates based on effective counter diabatic driving, in platforms ranging from superconducting circuits to Rydberg atoms. We briefly sketch as well related ideas to control many-body interactions and evolution errors by compensating terms in the Hamiltonian.
