Accelerated Training Convergence in Superposed Quantum Networks
NATO Advanced Study Institute, Villa Cagnola, Italy
Acrobat
PDF
We outline a training framework for adaptive quantum networks which aims to simultaneously optimize both topological and numerical structure. The procedure is unique in harnessing a coherent ensemble of discrete topological configurations of neural networks, each of which is formally merged into the appropriate linear state space via superposition. Training is carried out within this coherent state space, allowing for parallel revision of differing topological configurations at each step. The formalism provides quantitative, numerical indications for optimal reconfiguration of network topology. Candidate physical implementations for the model are drawn from recent developments in condensed matter physics and solid-state quantum information processing.

Superpositional
Quantum Network Topologies
International
Journal of Theoretical Physics
Acrobat

We introduce superposition-based
quantum networks composed of
(i)
the classical perceptron model of multilayered, feedforward
neural networks and
(ii)
the algebraic model of evolving reticular quantum structures
as described in quantum gravity. The main feature of this
model is moving from particular neural topologies to a
quantum metastructure which embodies many differing topological
patterns. Using quantum parallelism, training is possible
on superpositions of different network topologies. As
a result, not only classical transition functions, but
also topology becomes a subject of training. The main
feature of our model is that particular neural networks,
with different topologies, are quantum states.
We consider high-dimensional quantum structures as candidates
for implementation of the model.

Quantum
State Engineering
with the rf SQUID
NATO
Advanced Research Workshop on Quantum Chaos
Acrobat PDF
The SQUID, or superconducting quantum
interference device, is a highly sensitive instrument
employed for the nondestructive measurement of magnetic
fields, with a host of applications in both biophysics and
materials technology. It is composed of a cooled superconductive
metal ring separated by a thin insulating barrier of non-superconducting
metal. Electrons tunnel across the barrier to form a Josephson
junction; an
rf SQUID
is essentially a Josephson junction with tunable current
and energy. Quantum computers take advantage of the superpositional
logic of quantum mechanics to allow for dramatic increases
in computational efficiency.
rf SQUIDs
show potential for quantum computing applications by forming
the qubit component of a quantum computer, through simply
treating the direction of current, clockwise or counterclockwise,
as the value of the bit.

Microlens array fabrication via microjet printing technologies –
Future directions in quantum communications and coherent information processing
Workshop on Optical Fabrication Technologies, FISBA Optik, TU Delft
Acrobat PDF
We review recent advances in optical microlens array fabrication using piezoelectric microchannel mounted nozzles to deposit polymer droplets to various substrates via drop-on-demand (DOD) fashion. The technique produces microlenses in a similar fashion to photoresist and can be employed to produce spherical and nonspherical lenses on the order of 20µm to 3mm at rates of up to 25 kHz on demand. Advantages include high reproducibility, flexibility and process automation while offering a simple and cost-effective fabrication solution to produce microlens arrays in multiple application domains.

Converging Technologies: The Future of the Global Information Society
UNISCA
First Committee on Disarmament and International Security
Acrobat PDF
The complex web of the global information
grid will undergo explosive changes over coming decades.
As advances in science and technology converge, a myriad
array of discoveries in biotechnology, nanotechnology
and information technology will produce unpredictable
effects that must be accounted for in any estimate of
what the world will look like in this future. A strategically
important feature of this world will be the emerging trend
of information warfare. Though still immature at present
day, this trend will become increasingly dominant in the
years to come. The information warfare of tomorrow will
be radically different from its prototype today. No longer
will it be confined to the mainframes of the Internet
or to corporate databases: the battleground of the future
will draw into its scope the scientific advances being
made today in bio and nano technologies.
The divisions between man and machine will blur. When
networked technologies are ubiquitous, a state-sponsored
attack on electronic networks can have far-reaching, and
devastating, physical consequences.

Quantum
Uncertainty: The Boundaries
of Empirical Knowledge
Towards a Science of Consciousness, MIT Press
Acrobat PDF
Modern
science has held unprecedented success in describing the
workings of the
universe. Quantum electrodynamics – the capstone
of 20th century scientific endeavour – is one of
the most accurately demonstrated theories in history.
It predicts the behaviour of the physical world to unparalleled
precision, and it has driven the most revolutionary of
our modern technological innovations. But this most fundamental
of physical theories is far from complete. The more deeply
we peer into the fundamental workings of the universe,
the more we find that we have to impose limitations not
only upon what we know, but on what we can know

Evolving
Consciousness in Silico
Towards
a Science of Consciousness, MIT Press
Acrobat PDF
The study of consciousness and its origins has experienced
radical breakthroughs with the advent of emerging technologies
in the field of neuroscience. Once overcast with a veil
of mystery, the inner workings of the brain have undergone
profound illuminations made possible by rapid advances
in the computing industry coupled with insights gleaned
through physics and the medical sciences. New technologies
such as MRI, MEG, and PET scanning have enabled scientists
to understand the neurological correlates of mental processes
in ever finer detail, allowing them to glimpse the interior
of a fully functioning brain in real-time. However, even
with these exponential advances in the field of neuroscience,
laying a theoretical foundation to explain precisely how
consciousness arises remains a cryptic and insurmountable
task. The most important scientific discovery of our time
will be when this problem is resolved.

Society
and the Future
of Artificial Intelligence
2001 French Senate Hearing
Society will soon face a crossroads. Advancing technology
has already enabled us to glimpse into the inner workings
of the brain. What will we do with this knowledge when
it allows us to control and to duplicate the very processes
that give birth to the mind? The French Senate convened
earlier this year to examine this difficult question,
bringing together leading scientists from around the world
to speculate on the potential impact artificial intelligence
will have on the future of society.
