Quantum communication with realistic devices
Abstract: Quantum key distribution is proven to offer unconditional security in communication between two remote users with ideal devices. Unfortunately, ideal devices never exist in practice and dev...

Quantum Journal Club: Chip-Scale Nanofabrication of Single Spins and Spin Arrays
Abstract: We demonstrate a technique to nanofabricate nitrogen vacancy (NV) centers in diamond based on broad-beam nitrogen implantation through apertures in electron beam lithography resist. This me...

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...
