Quantum Control of Superconducting Circuits
内容： We develop an efficient scheme that allows for arbitrary operations on a cavity mode using a strongly dispersive qubit-cavity interaction and time-dependent drives. The scheme can readily be im...

Tackling decoherence via weak quantum measurement and quantum measurement revers
内容： Decoherence, often caused by unavoidable coupling with the environment, leads to degradation of quantum coherence. For a multipartite quantum system, decoherence leads to degradation of entangl...

QUIC seminar: Multipartite Quantum Correlations in Open Quantum Systems
内容： In this work, we present a measure of quantum correlation for a multipartite system, defined as the sum of the correlations for all possible partitions. Our measure can be defined for quantum d...
