Quantum Control of Superconducting Circuits
Abstract: 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 b...

Tackling decoherence via weak quantum measurement and quantum measurement revers
Abstract: 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 ent...

QUIC seminar: Multipartite Quantum Correlations in Open Quantum Systems
Abstract: 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 quant...

Quantum Journal Club: Quantum Discord and the Power of One Qubit
Abstract: We use quantum discord to characterize the correlations present in the model called deterministic quantum computation with one quantum bit (DQC1), introduced by Knill and Laflamme [Phys. Re...

Quantum Journal Club: Detection and Control of Individual Nuclear Spins Using a
Abstract: We experimentally isolate, characterize, and coherently control up to six individual nuclear spins that are weakly coupled to an electron spin in diamond. Our method employs multipulse sequ...
