"PHOTONIC QUANTUM ENTANGLEMENT FOR TECHNOLOGIES AND APPLICATIONS:
TOWARDS THE QUANTUM INTERNET"
THOMAS JENNEWEIN, UNIVERSITY OF WATERLOO, CANADA
Quantum information processing and quantum communication are novel
protocols that originate in the very fundamental and philosophical
questions on superposition and entanglement first raised about 100
years ago in the early days of quantum mechanics. Strikingly, these
new protocols offer capabilities beyond communication task possible
with classical physics. One very important example is the secure key
exchange based on the transmission of individual quantum signals
between communication partners. The big vision and frontier in the
field of quantum communication research is the development of a
Quantum Internet, which establishes entanglement between many
different users and devices. The basic idea is that similar to
today’s internet, the Quantum Internet will readily transfer quantum
bits, rather than today’s classical bits, between users near and far
and over multiple different channels. This Quantum Internet could be
useful for secure communications, quantum computing networks and
metrological applications such as better time keeping or enhanced
telescopes. I will discuss recent advances on implementations and
tools useful for generating and distributing photonic quantum
entanglement, as well as our work towards the Canadian quantum
satellite mission, QEYSSAT, that will demonstrate transmission quantum
signals from ground to space in the goal to cover global distances.
"SEMICONDUCTOR NANOSTRUCTURES PRODUCING SINGLE PHOTONS, TWINS AND
TRIPLETS FOR QUANTUM PHOTONICS"
GREGOR WEIHS, UNIVERSITY OF INNSBRUCK
While photonics is an established area of technology covering optical
communication, manufacturing, sensing, and many other fields of
application, hardly any of its methods actually make use of the
quantization of light. Quantum photonics applications, on the other
hand, explicitly build on the quantum properties of light to realize
secure key distribution, optical quantum computing, and quantum
computer networks.
Sources of quantum states of light are important building blocks of
such quantum photonic systems. Traditionally these sources were
realized using nonlinear optical techniques in conventional optical
laboratory setups but for any real world applications, it is clear
that we need to achieve miniaturization and integration. In our work,
we employ single semiconductor quantum dots, nanowires, and waveguides
to implement sources of single photons, entangled photon pairs and
even triplets of photons. While there are still many open research
questions, these sources have the potential to make quantum photonics
a practical reality.
"FROM LOCAL REALISM INTO A GLOBAL QUANTUM AGE"
HANNES HÜBEL, AIT AUSTRIAN INSTITUTE OF TECHNOLOGY, VIENNA
In this talk I will review the concept of entanglement, how it
radically changed our understanding of the world we live in and its
usage in quantum communication applications. Quantum key distribution
(QKD) will be highlighted as one of the most technologically advanced
application of quantum communication. There I will discuss current
trends to incorporate QKD into telecommunication networks together
with advances on photonic integration that will allow QKD to achieve a
widespread use from industrial players to home users.
"QUANTUM INFORMATION PROCESSING WITH SUPERCONDUCTING CIRCUITS"
GERHARD KIRCHMAIR, UNIVERSITY OF INNSBRUCK
Superconducting quantum circuits are one of the most promising
platforms for realizing a quantum computer. In this talk I will
present some of the research activities of the Superconducting Quantum
Circuits group in Innsbruck. I will give a short introduction to
circuit quantum electrodynamics and highlight the progress of
superconducting qubits. I will then show, how this architecture can be
used to realize a platform for quantum computation and for simulating
interacting quantum many-body systems.
„FROM QUANTUM FOUNDATIONS TO QUANTUM COMPUTING“
PHILIP WALTHER, UNIVERSITY OF VIENNA
This talk reviews the impressive pioneering work in quantum photonics
up to the current stage of photonic quantum computers. The advantages
of photonic systems have not only enabled fundamental experimental
investigations of quantum physics, but have also led to novel
applications such as quantum computing and even quantum cloud
networks. The talk will finish with a brief overview of
special-purpose quantum computers whose applications are uniquely
suited to optics.
„SKIN-INSPIRED ELECTRONICS“
ZHENAN BAO, STANFORD UNIVERSITY, USA
Skin is the body’s largest organ, and is responsible for the
transduction of a vast amount of information. This conformable,
stretchable, self-healable and biodegradable material simultaneously
collects signals from external stimuli that translate into information
such as pressure, pain, and temperature. The development of electronic
materials, inspired by the complexity of this organ is a tremendous,
unrealized materials challenge. However, the advent of organic-based
electronic materials may offer a potential solution to this
longstanding problem.
My group has been working on understanding of the fundamental design
principles of new electronic materials that have skin-like properties,
such as stretchability, self-healing ability and biodegradabaility
while maintaining excellent electronic properties. We realized
artificial skin with sensitivity and stretchability comparable to that
of human skin. We demonstrated artificial mechanoreceptors and
artificial nerve systems. In turn, the basic inventions of materials
and devices enabled a new generation of skin conformal electronics
that can be used for health monitoring wearables, wireless and
biodegradabale implantable sensors for tendon repair and
neuroprostheses.
"FERROELECTRIC POLYMERS FOR SENSITIVE OBJECT SURFACES"
BARBARA STADLOBER, JOANNEUM RESEARCH, GRAZ
Ferroelectric polymers from the PVDF-family have proven to be
multifunctional and self-sustaining materials with a broad application
range in printed and flexible electronics. They can be used for
detecting dynamic and static mechanical excitations such as pressure
or force, touch, impact and strain, for sensing human-body radiation
and proximity, as vibration sensors for structure-bourne sound
detection, as seamlessly integrated acoustics devices, as stretchable
vital parameter sensors for movement, ECG and respiratory rate
monitoring, as well as piezoelectric energy harvesting elements. Last
but not least PVDF-based fluoropolymer can also be used as actuators.
These rich properties promote the deployment of ferroelectric polymer
sensor and actuator films for sensitive object surfaces within IoT
scenarios, especially if they can be processed on versatile, flexible
and lightweight substrates of 2D or 3D format at low-costs (e.g. by
printing) and over large areas.
„QUANTUM DOT LIGHT EMITTERS: FROM DISPLAYS TO ENABLING A NEW
GENERATION OF ENERGY CONVERSION SYSTEMS“
A. PAUL ALIVISATOS, UNIVERSITY OF CALIFORNIA, BERKELEY, USA
Nanoscience has provided a new approach for designing materials that
absorb and emit light and transport charges efficiently. These are
fundamental steps that underlie many energy conversion technologies.
This presentation will focus on colloidal quantum dots, and how they
can be made to absorb and emit light, as well as to transport charge
efficiently. When the principles of nanoscience are used to prepare a
small piece of semiconductor that is fully isolated from the
environment,
it can behave as a nearly ideal light absorber and emitter. These
“quantum dots” have now left the lab and moved into practical use,
as they are widely used today in a new generation of extremely energy
efficient displays that provide exceptional color purity. The
efficiency of light emission from these quantum dots is so close to
unity that it is actually requires new approaches to measure
accurately. This in turn has prompted us to investigate what happens
when quantum dot light emitters approach the thermodynamic limit of
their luminescence efficiency. This talk will describe some entirely
new energy conversion processes that may be enabled for the first time
by using such nearly ideal light emitters. If time permits, I will
also describe recent work on a new approach to extremely efficient
ultrafast charge transport in quantum dot films.
"RATIONAL DESIGN OF THERMOELECTRIC MATERIALS FROM NANOCRYSTAL BUILDING
BLOCKS"
MARIA IBANEZ, INSTITUTE OF SCIENCE AND TECHNOLOGY AUSTRIA,
KLOSTERNEUBURG
Nanocrystals can be envisioned as artificial atoms to build-up
materials from. Colloidal synthetic routes are capable to yield
nanocrystals with precise control of size, shape, crystalline phase
and composition, thus allowing to accurately engineer such artificial
atoms. Beyond nanocrystal design, another key player on the
building-up process is the nanocrystal surface. The possibility to
modify nanocrystal surface chemistry opens a new degree of freedom to
tune final nanomaterial properties, defining the surface ligand as a
building block on its own. Last but not least, the functional
properties are as well determined by the nanocrystals organization,
interconnection, packing density and relative crystal orientation in
the final nanomaterial. Herein, we will focus on the synthesis of
nanoparticles with precisely engineered composition and surface
chemistry, and their combination and consolidation into nanostructured
materials to target the needs of thermoelectricity.
"ENERGY CONVERSION AND ENERGY STORAGE BY MOVING IONS IN SOLIDS"
JÜRGEN FLEIG, UNIVERSITY OF TECHNOLOGY, VIENNA
Improved and also novel approaches are required for chemically storing
electrical energy and for efficiently converting chemical and
electrical energy. Moving and reacting ions in solids play an
essential role in those technologies. State of the art rechearchable
lithium ion batteries, for example, rely on the motion of ions in
electrodes and future improvements can be expected from exploiting
also ion transport in solid electrolytes. Power to gas technologies
such as electrolysis of water can strongly benefit from highly mobile
and reactive ions in solids and the same is true for fuel cells used
for efficient chemical to electrical energy conversion. Moreover, ion
motion can be triggered by interaction with light, which may open
novel paths to energy storage but can also hamper operation of
devices, e.g. perovskite solar cells.
