Quantum optimal control, a toolbox for devising and implementing the shapes of
external fields that accomplish given tasks in the operation of a quantum device
in the best way possible, has evolved into one of the cornerstones for enabling
quantum technologies. The last few years have seen a rapid evolution and
expansion of the field. We review here recent progress in our understanding of

AbstractMicrogravity eases several constraints limiting experiments with
ultracold and condensed atoms on ground. It enables extended times of flight
without suspension and eliminates the gravitational sag for trapped atoms. These
advantages motivated numerous initiatives to adapt and operate experimental
setups on microgravity platforms. We describe the design of the payload,
motivations for desi... hiện toàn bộ

Commercial applications of quantum computing Tập 8 Số 1 - 2021
Francesco Bova, Avi Goldfarb, Roger G. Melko
AbstractDespite the scientific and engineering challenges facing the development
of quantum computers, considerable progress is being made toward applying the
technology to commercial applications. In this article, we discuss the solutions
that some companies are already building using quantum hardware. Framing these
as examples of combinatorics problems, we illustrate their application in four

A conformal array of microfabricated optically-pumped first-order gradiometers for magnetoencephalography - 2020
Nicholas V. Nardelli, Abigail R. Perry, Sean Krzyzewski, Svenja Knappe
AbstractAn array of 21 first-order gradiometers based on zero-field
optically-pumped magnetometers is demonstrated for use in
magnetoencephalography. Sensors are oriented radially with respect to the head
and housed in a helmet with moveable holders which conform to the shape of a
scalp. Our axial gradiometers have a baseline of 2 cm and reject laser and
vibrational noise as well as common-mode en... hiện toàn bộ
Towards security recommendations for public-key infrastructures for production environments in the post-quantum era Tập 8 - Trang 1-19 - 2021
Sergey E. Yunakovsky, Maxim Kot, Nikolay Pozhar, Denis Nabokov, Mikhail Kudinov, Anton Guglya, Evgeniy O. Kiktenko, Ekaterina Kolycheva, Alexander Borisov, Aleksey K. Fedorov
Quantum computing technologies pose a significant threat to the currently
employed public-key cryptography protocols. In this paper, we discuss the impact
of the quantum threat on public key infrastructures (PKIs), which are used as a
part of security systems for protecting production environments. We analyze
security issues of existing models with a focus on requirements for a fast
transition to ... hiện toàn bộ
Field trial of a three-state quantum key distribution scheme in the Florence metropolitan area - 2019

Abstract In-field demonstrations in real-world scenarios boost the development
of a rising technology towards its integration in existing infrastructures.
Although quantum key distribution (QKD) devices are already adopted outside the
laboratories, current field implementations still suffer from high costs and low
performances, preventing this emerging technology from a large-scale deployment
