Direct observation of nanofabrication influence on the optical properties of single self-assembled InAs/GaAs quantum dots [PDF]
Phys. Rev. Applied 9, 064019 (2018), 2017 Single self-assembled InAs/GaAs quantum dots are a promising solid-state quantum technology, with which vacuum Rabi splitting, single-photon-level nonlinearities, and bright, pure, and indistinguishable single-photon generation having been demonstrated.

Ultrafast multi-focus 3-D nano-fabrication based on two-photon polymerization
Nature Communications, 2019 Two photon polymerization (TPP) allows nanofabrication of three dimensional objects with complex geometries, but is considered to be slow with a limited fabrication rate.

Spin Wave Magnetic NanoFabric: A New Approach to Spin-based Logic Circuitry [PDF]
, 2007 We propose and describe a magnetic NanoFabric which provides a route to building reconfigurable spin-based logic circuits compatible with conventional electron-based devices. A distinctive feature of the proposed NanoFabric is that a bit of information is encoded into the phase of the spin wave signal.

Deterministic positioning of nanophotonic waveguides around single self-assembled quantum dots [PDF]
APL Photon. 5, 086101 (2020), 2019 The capability to embed self-assembled quantum dots (QDs) at predefined positions in nanophotonic structures is key to the development of complex quantum photonic architectures. Here, we demonstrate that QDs can be deterministically positioned in nanophotonic waveguides by pre-locating QDs relative to a global reference frame using micro ...

Negative Refractive Index in Artificial Metamaterials [PDF]
Optics Letters, vol. 31, 2483-2485 (2006), 2006 We discuss optical constants in artificial metamaterials showing negative magnetic permeability and electric permittivity. Using effective field theory, we calculate effective permeability of nanofabricated media composed of pairs of identical gold nano-pillars with magnetic response in the visible spectrum.

Development of Yttrium alloy ion source and its application in nanofabrication [PDF]
, 2016 We present a new YAuSi Liquid Metal Alloy Ion Source (LMAIS), generating focused ion beams of yttrium ions, and its prospective applications for nanofabrication, sample preparation, lithographic and implantation processes. Working parameters of the AuSiY LMAIS are similar to other gold-silicon based LMAIS.

Quantum Wires and Quantum Dots for Neutral Atoms [PDF]
Eur.Phys.J.D4:57,1998, 1998 By placing changeable nanofabricated structures (wires, dots, etc.) on an atom mirror one can design guiding and trapping potentials for atoms. These potentials are similar to the electrostatic potentials which trap and guide electrons in semiconductor quantum devices like quantum wires and quantum dots.
