DESCRIPTION:\n\nUniversity of Copenhagen\, June 17-21\, 2019\n\nInformatio
n and communication technologies are essential to modern society as the in
ternet is pervading all aspects of our lives. Quantum mechanics imposes a
fundamental limit to the communication rates\, whose determination is a pi
votal challenge. Given the amount of sensitive information sent through th
e internet\, secure communications are essential to our society. To fulfil
l this need\, the EU is investing in quantum key distribution with the 1G
€ Quantum Technology Flagship\, which has been just launched on October
29\, 2018. Quantum key distribution is a technique to generate a secret ke
y shared between two parties. The essential feature of quantum mechanics i
s that any measurement of a system unavoidably disturbs it. Quantum key di
stribution exploits this feature to detect any attempt of intercepting the
communication and hence guarantee the security of the key. Determining th
e maximum rate for secure communication that can be achieved by the forthc
oming generation of devices for quantum key distribution is another pivota
l challenge. All the internet traffic travels through electromagnetic sign
als\, which also provide the most promising platform for quantum key distr
ibution. Quantum Gaussian channels provide the mathematical model for the
propagation of electromagnetic signals in the quantum regime\, where class
ical mechanics is no longer valid. The mathematical theory of communicatio
n with quantum channels was developed by Prof. Alexander Holevo\, one of t
he founding fathers of quantum information. The determination of the maxim
um communication rates of quantum Gaussian channels had been a longstandin
g open problem for ten years\, and was finally solved by Prof. Vittorio Gi
ovannetti together with Prof. Holevo and Prof. Raúl García-Patrón. Prof
. Holevo and Prof. Giovannetti will give lectures on communication with qu
antum channels\, with particular focus on their recent fundamental advance
on quantum Gaussian channels. Quantum key distribution will be a fundamen
tal topic of the master class. Prof. Robert König will give an introducto
ry lecture\, and Prof. García-Patrón will give a lecture on the most rec
ent and promising continuous variable protocols. These lectures will bring
the participants to the forefront of the research on quantum communicatio
n\, with the goal of making them able to start a research project both com
pletely theoretical or in collaboration with experimental groups.\n\nA fun
damental part of the Quantum Technology Flagship is constituted by quantum
computing. Quantum computers will be able to exploit quantum-mechanical e
ffects to exponentially reduce the time required for certain computations\
, among which the factoring problem. A rapidly developing field of researc
h is finding new algorithms for quantum computers to extend the set of pro
blems where they have an advantage over classical computers. Prof. Seth Ll
oyd ideated one of the most important algorithms for quantum computers\, a
nd he will give a guest lecture on quantum computation with continuous var
iables. This lecture will complement the topics of the lectures on quantum
communication and will offer the participants a broader perspective on th
e applications of continuous variable platforms.\n\n \n\nLearning outcome
\n\n\nBy the end of the course\, the participants will have acquired an up
-to-date overview of the latest work in these areas and should be prepared
for further study as well as embarking on related research projects on th
eir own.\n \n\nTarget group\n\n\nThis master class will be of high intere
st for all the students and early career researchers interested in quantum
communication and continuous variable platforms\, both from a mathematica
l and from a physical perspective.\n\n \n\n \n\nSpeakers include:\n\n\n
Vittorio Giovannetti\, Scuola Normale Superiore\, Pisa\n Alexander Holevo\
, Steklow Mathematical Institute\, Moscow\n Seth Lloyd\, Massachusetts Ins
titute of Technology\n Robert König\, Institute for Advanced Study & Zent
rum Mathematik\, Technische Universität München\n Raúl García-Patron S
ánchez\, QuIC\, Université Libre de Bruxelles \n Giacomo De Palma\, Q
MATH\, University of Copenhagen\n\n\n \n\nTeaching and learning methods\n
\nLectures and exercise classes.\n\nLocation\n\nThe master class will take
place at the University of Copenhagen\, Denmark. Copenhagen is a beautif
ul harbor city\, famous for being among the safest and most enjoyable plac
es to live in the world.\nParticipants of the master class will have the o
pportunity to explore the city from the water during an excursion. Conveni
ently\, May and June are the sunniest months of the year in Copenhagen\, w
ith days lasting nearly 17 hours.\n\nOrganizers\n\n\nThe master class is o
rganized by the Villum Centre for the Mathematics of Quantum Theory (QMATH
) at the Department of Mathematical Sciences and the Niels Bohr Internat
ional Academy (NBIA). From QMATH the organizers are:\n \nGiacomo De Palm
a\nAlbert H. Werner\nJan Philip Solovej\nMatthias Christandl\nSuzanne Ande
rsen\n\nVenue\n\nThe QMATH group is located at the MATH department in the
H.C. Ørsted Institute across the park. Directions to the MATH departm
ent\, and several other useful locations\, can be found here.\n\n \n\n
\n\nAccommodation\n\nWe recommend Hotel 9 Små Hjem\, which is pleasant a
nd inexpensive and offers room with a kitchen. Another inexpensive option
is CabInn\, which has several locations in Copenhagen: Hotel City\, Hot
el Scandivania\, and Hotel Express. Somewhat more expensive\, but still
recommended\, options are Hotel Nora and Ibsen's Hotel. PhD and Master'
s students have the possibility to apply for funded accommodation.\n\nAppl
ication\n\nAn on-line application is required to be able to participate in
the master class.\n\nThe on-line application is now possible.\n\nThe appl
ication deadline is April 15 2019.\n\nParticipants will be selected on t
he basis of the applications. For PhD students\, indicating the e-mail add
ress of an academic supervisor is required\, as well as a motivated explan
ation of the interest in the workshop. The master class is worth 2.5 ECTS.
