Writing Artists’ Lives Across Nations and Cultures: Biography, Biofiction and Transnationality
Full text linkAs an introduction to the volume, this chapter explores recent developments relating to the study and practice of biography across nations and cultures, discussing key issues in the humanities that have significant implications for writing the lives of writers, musicians and visual artists. These include the resurgence in scholarly interest in artists’ biographies; the rise of biofiction and the ways in which this mode of writing is distinguished from biography; the death and return of the Author; and the prominence that transnationality has assumed in studies of life writing, challenging the traditional framework of the nation-state. It also outlines the aims and scope of the volume, and concludes with a one-paragraph summary of each of its chapters in turn
Unifying S\o rensen-M\o lmer gate and Milburn gate with an optomechanical example
Full text linkS\o rensen-M\o lmer gate and Milburn gate are two geometric phase gates,
generating nonlinear self-interaction of a target mode via its interaction with
an auxiliary mechanical mode, in the continuous and pulsed interaction regime,
respectively. In this paper, we aim at unifying the two gates by demonstrating
that S\o rensen-M\o lmer gate is the continuous limit of Milburn gate,
emphasising the geometrical interpretation in the mechanical phase space. We
explicitly consider imperfect gate parameters, focusing on relative errors in
time for S\o rensen-M\o lmer gate and in phase angle increment for Milburn
gate. We find that, although the purities of the final states increase for the
two gates upon reducing the interaction strength together with traversing the
mechanical phase space multiple times, the fidelities behave differently. We
point out that, the difference exists because the interaction strength depends
on the relative error when taking the continuous limit from the pulsed regime,
thereby unifying the mathematical framework of the two gates. We demonstrate
this unification in the example of an optomechanical system, where mechanical
dissipation is also considered. We highlight that, the unified framework
facilitates the new method of deriving the dynamics of the continuous
interaction regime without solving differential equations.Comment: 13 pages including Appendix, 8 figures, accepted by Physical Review
Exemplary Europeans. Romain Rolland and Stefan Zweig
No full textThe friendship between Romain Rolland (1866-1944) and Stefan Zweig (1881-1942) offers a prime example of intellectual encounter in interwar Europe. The two writers maintained intensive contact between the World Wars and exchanged ideas on the future of Europe and the role of literature in the revitalisation of European values. A particularly interesting aspect of their dialogue is the discussion of literary and biographical methods of writing Europe. A close look at the personal and literary relations of Rolland and Zweig will illustrate that cross-border encounters played a crucial role in the development of new intellectual approaches to the recovery of Europe after the First World War
Introduction: European Encounters. Intellectual Exchange and the Rethinking of Europe (1914-1945)
No full textThis introductory chapter explores the concepts of intellectual 'encounter' and 'exchange' that are central in this volume. It addresses theoretical and methodological issues related to historical research on the interwar period as an age of intense cultural exchange among writers, artists and academics who are directly or indirectly engaged with the reevaluation of the concept 'Europe'. The transnational perspective is offered as a tool for analyzing cross-border encounters within a European context. Europe is presented here as both an idea and a zone of intellectual exchange. More specifically, the concepts of European 'spaces' and 'Europeanization' are used to study the relevance of encounters and exchange for the rethinking of Europe

Toward a M{\o}lmer S{\o}rensen Gate With .9999 Fidelity
Full text linkRealistic fault-tolerant quantum computing at reasonable overhead requires
two-qubit gates with the highest possible fidelity. Typically, an infidelity of
is recommended in the literature. Focusing on the
phase-sensitive architecture used in laboratories and by commercial companies
to implement quantum computers, we show that even under noise-free, ideal
conditions, neglecting the carrier term and linearizing the Lamb-Dicke term in
the Hamiltonian used for control-pulse construction for generating
M{\o}lmer-S{\o}rensen XX gates based on the Raman scheme are not justified if
the goal is an infidelity target of . We obtain these results with a
gate simulator code that, in addition to the computational space, explicitly
takes the most relevant part of the phonon space into account. With the help of
a Magnus expansion carried to the third order, keeping terms up to the fourth
order in the Lamb-Dicke parameters, we identify the leading sources of coherent
errors, which we show can be eliminated by adding a single linear equation to
the phase-space closure conditions and subsequently adjusting the amplitude of
the control pulse (calibration). This way, we obtain XX gates with infidelities
