The Landscape of Academic Literature in Quantum Technologies
In this study, we investigated the academic literature on quantum
technologies (QT) using bibliometric tools. We used a set of 49,823 articles
obtained from the Web of Science (WoS) database using a search query
constructed through expert opinion. Analysis of this revealed that QT is deeply
rooted in physics, and the majority of the articles are published in physics
journals. Keyword analysis revealed that the literature could be clustered into
three distinct sets, which are (i) quantum communication/cryptography, (ii)
quantum computation, and (iii) physical realizations of quantum systems. We
performed a burst analysis that showed the emergence and fading away of certain
key concepts in the literature. This is followed by co-citation analysis on the
highly cited articles provided by the WoS, using these we devised a set of core
corpus of 34 publications. Comparing the most highly cited articles in this set
with respect to the initial set we found that there is a clear difference in
most cited subjects. Finally, we performed co-citation analyses on country and
organization levels to find the central nodes in the literature. Overall, the
analyses of the datasets allowed us to cluster the literature into three
distinct sets, construct the core corpus of the academic literature in QT, and
to identify the key players on country and organization levels, thus offering
insight into the current state of the field. Search queries and access to
figures are provided in the appendix.Comment: 32 pages, 10 figures, draft version of a working pape
Towards Prediction of Financial Crashes with a D-Wave Quantum Computer
Prediction of financial crashes in a complex financial network is known to be
an NP-hard problem, i.e., a problem which cannot be solved efficiently with a
classical computer. We experimentally explore a novel approach to this problem
by using a D-Wave quantum computer to obtain financial equilibrium more
efficiently. To be specific, the equilibrium condition of a nonlinear financial
model is embedded into a higher-order unconstrained binary optimization (HUBO)
problem, which is then transformed to a spin- Hamiltonian with at most
two-qubit interactions. The problem is thus equivalent to finding the ground
state of an interacting spin Hamiltonian, which can be approximated with a
quantum annealer. Our experiment paves the way to study quantitative
macroeconomics, enlarging the number of problems that can be handled by current
quantum computers
The Language of the cybersouls
Debates about technology are mostly staged in a grand setting: presented as the sinister toolkit of authoritarian organisations, or as the progressive fabric of the future. Yet everyone is involved in technology as part of every microscopic action in every humdrum life. How do theories about technology cope with this political spectrum? One option is to treat technology as we treat language and specifically use Wittgenstein’s language games as an analogy. So that technology, like language, becomes inseparable from us and an intimate part of us, and this merging of technology and the human transforms us all into cyborgs
