SUMMARY:Семинар “Problems and Methods Related to Coding Theory“
DESCRIPTION:Семинарът  \nProblems and Methods Related to Coding Theory\,\nорганизиран от \nИМИ – БАН\, Секция “Математически основи на информатиката”\, \n Novosibirsk State University\, Novosibirsk\, Russia\, и \n Sobolev Institute of Mathematics\, Siberian Branch of  the Russian Academy of Sciences\, Novosibirsk\, Russia \nВи кани на поредната си сбирка\, на която \nAssist. Prof. Ivan Mogilnykh\, Novosibirsk State University\,\nще изнесе доклад на тема: \nCompletely regular codes in Johnson and Grassmann graphs\nAbstract. Completely regular codes in Johnson and Grassmann graph are interrelated with t-designs. In this talk we give an introduction to these codes and discuss several old and recent results. Martin noted that any (k-1)-(n\,k\,1)-design D is a completely regular code in the Johnson graph J(n\,k). Avgustinovich and Mogilnykh showed that {B:|B|=k+1\, B does not contain any blocks of D} is a completely regular code in J(n\,k+1). \nWe prove that when D is the Steiner quadruple system of the extended Hamming code of length n one can obtain the following completely regular code in J(n\,6): {B:|B|=6\, B does not contain any blocks of D}. \nAnalogous ideas yield a completely regular code in Grassmann graph Jq(n\,4) from Desarguesian line spread. \nСтраница на семинара: http://www.math.bas.bg/moiuser/PMCT/ \n Семинарът ще се проведе онлайн на 30 март (вторник) 2021 г. от 13:00 часа. \nJoin Zoom Meeting \nhttps://us02web.zoom.us/j/85193428253?pwd=NzIycEVQb0NEMzFReVE1aTVOU3JWQT09\nZoom ID: 851 9342 8253\nPasscode: 970063

SUMMARY:Семинар на секция “Математически основи на информатиката”
DESCRIPTION:Секция „МАТЕМАТИЧЕСКИ ОСНОВИ НА ИНФОРМАТИКАТА“ \nорганизира семинар по проект \n„Стратегии за подобряване на качеството на моделите\, намерени от алгоритми за машинно обучение с приложение към квантовата томография“. \nДоклад ще изнесат: \nВиолета Иванова-Ролинг и Никлас Ролинг\nна тема: \nQuantum state tomography as a numerical optimization problem\nАбстракт: We present a framework that formulates the quest for the most efficient quantum state tomography scheme as an optimization problem which can be solved numerically. This approach can be applied to a broad spectrum of relevant setups including measurements restricted to a subsystem. To illustrate the power of this method we present results for the six-dimensional Hilbert space constituted by a qubit-qutrit system\, which could be realized e.g. by the N-14 nuclear spin-1 and two electronic spin states of a nitrogen-vacancy center in diamond. Measurements of the qubit subsystem are expressed by projectors of rank three\, i.e.\, projectors on half-dimensional subspaces. For systems consisting only of qubits\, it was shown analytically that a set of projectors on half-dimensional subspaces can be arranged in an informationally optimal fashion for quantum state tomography\, thus forming so-called mutually unbiased subspaces. Our method goes beyond qubits-only systems and we find that in dimension six such a set of mutually-unbiased subspaces can be approximated with a deviation irrelevant for practical applications. \nСеминарът ще се проведе на 30 март (вторник) 2021 г. от 18:00 часа онлайн чрез Zoom. \nJoin Zoom Meeting\nhttps://us02web.zoom.us/j/89537593729?pwd=Wm9LYmhNeEZ5YlNkaGQvblNwMnlZdz09 \nMeeting ID: 895 3759 3729\nPasscode: 021763
