Advanced optical devices have the potential to satisfy the ever-increasing requirements of computing and communication systems. Applications can be envisioned in computational algorithms, in data transfer and routing, in memory and storage, and in clock stability. Increasingly these applications exploit the coherent and quantum characteristics of the interactions of optical fields with atomic and nanostructured materials. These are variously represented by optical and quantum interference and quantum entanglement phenomena; by spectral discrimination and dispersion of resonant transitions; and by incorporation of nonlinearity and feedback. The promises of quantum computing are well-recognized. They depend on the realization of material systems that exhibit slow decoherence as well as singular interactions with data and control signals from the programming environment. Development of these attributes is near fruition in optical materials with laser-born signal interactions. This capability is a continuing theme of this conference.

These principles connect naturally to those of quantum interconnects, dependent for bandwidth, power efficiency, timing and fidelity on the attributes of entanglement. Alternatively, manipulation of atomic or morphological dispersion can impact this requirement. Interfacing between different photonic and material systems is critical to the development of practical quantum information processing, as storage, processing nodes, and communication links will likely not all be directly compatible. Interfaces will include single-photon frequency and bandwidth conversions and conversions between photonic and material states as well as the development of hybrid photonic components. Possible systems include atoms, Rydberg atoms, spins, quantum dots, rare earth ions, photonic crystal molecules all of which may be in conventional and photonic crystal cavities. Another mechanism at the interface between quantum data processes and quantum communications, and amenable to implementation at sub-wavelength scale, is quantum plasmonics. The functionality of plasmons in connecting optical fields to charge oscillations comprises both electric and magnetic aspects, and can be manipulated by nano-scale morphology and materials properties, both inherent and engineered. Surface plasmon connections to boundary condition characteristics and super-resolution capabilities represent emerging capabilities.

Signal switching using the features of optical resonance represents an emerging application area. Important goals include few- and single-photon control of the switch, along with low energy dissipation and high frequency operation. These same attributes can also provide the foundation for accurate high-repetition-rate low-dissipation clocks. Feedback mechanisms with minimal dispersion that exploit recently identified nonlinearities could revolutionize this application. In memory applications, optics contributes both to high capacity and high data transfer. Spectral hole-burning, photon echo, and slow light are at various stages of development. Their introduction depends upon development of efficient interfaces to conventional computer systems requiring novel optoelectronic interfaces, including source and signal routing architectures and smart photodetectors. Device operation must be compensated by data encoding and error control codes to ameliorate noise and crosstalk. The objective of this conference is to bring together researchers whose expertise covers the entire spectrum between materials/devices and computer systems thus providing a forum for the discussion of the capabilities and limitations of advanced optical data manipulation, transfer, and memory for computing and communications capabilities.

Nano-sized optical probes, fluorescence nano-markers, and narrowband ultra-sharp filters have opened a door to possibilities of probing biological and quantum biological systems in all their details. Single cell plasmonic and spectroscopic probes can be used to couple optical radiation to the cell or even to a single molecule in it. The conference invites papers on living and non-living biological systems using novel concepts in quantum photonics and plasmonics. 

Quantum operations and devices that exploit them often depend on external bias and control. Bias fields, coherent and incoherent, cavities and slits, for example, are often treated classically – without noise, or with Poisson statistics – as if they do not derive from quantum ensembles. These, of course, also exhibit quantum characteristics which influence the throughput of the intended quantum operation. And of interest for a number of important applications is pushing these controls to the single-photon and single-particle level. Understanding and capability are maturing so that either the quantum aspects of these bias processes can be addressed and controlled or they can be supplanted by quantum-scale effects and operational concepts.

A newly-emerging photonics application is the use of photonic circuits to simulate quantum systems that are otherwise hard to test experimentally, such as extreme magnetic fields and topological states. With tools to fabricate large scale waveguide chips becoming more available photonic simulations of exotic systems is becoming a reality. The fabrication and control of such photonic chips is also of much practical interest for components in optical processing and communication systems. This conference invites papers on the full range of these topics.
 Diamond optical color centers, such as N-V centers, are recognized as the most interactive single-atom-like quantum mechanical systems. Such centers are addressable by single- and multiple-photon sources, can be entangled, and lately, can be produced with great control and precision on optical platforms. Thus, the so called "diamond photonics" has provided a new paradigm for nano-sensing and probing, quantum entanglement and computing, and, biophotonics with unprecedented precision and resolution.
 This conference will include special sessions on diamond and rare-earth photonics and biophotonics. The topics of interest will also include the quantum structures themselves; waveguides, dielectric resonators, metallic or plasmonic structures, and hybrid structures that combine bulk diamond or diamond nanoparticles with other materials.
