Abstract: Micro optical cavities can be used to collect photons emitted from the ions more efficiently, or to achieve strong coupling between photons and ions. In this talk, I will discuss a fundamen...
Abstract: No process in nature can perfectly copy an arbitrary quantum state. But is it possible to engineer processes that replicate quantum states with vanishingly small error? We devised a probabi...
Abstract: Surface distributions of two level system (TLS) defects and magnetic vortices are limiting dissipation sources in superconducting quantum circuits. Arrays of flux-trapping holes are commonl...
Abstract: Long-lived and high-fidelity memory for a photonic polarization qubit (PPQ) is crucial for constructing quantum networks. We present a millisecond storage system based on electromagneticall...
Abstract: The construction of a quantum computer remains a fundamental scientific and technological challenge because of the influence of unavoidable noise. Quantum states and operations can be prote...
Abstract: Statistical mechanics underlies our understanding of macroscopic quantum systems. It is based on the assumption that out-of-equilibrium systems rapidly approach their equilibrium states, fo...
