                Senin, 22 Oktober 2012

Random walks, Quantum walks, and Free Meixner Laws

Nobuaki Obata

Graduate School of Information Sciences

Tohoku University

 

In recent years, quantum walks have been studied extensively from various aspects in relation to quantum mechanics and quantum information. The concept of quantum walk was introduced as a quantum mechanical generalization of a random walk, but the correspondence is not straightforward. In this talk I will introduce the so-called Grover walk on a graph, in particular, on a spidernet, and discuss its peculiar property: localization.

 

A spidernet is a graph obtained from a rooted tree by suitably adding large cycles in each stratum defined by the distance from the root.

The free Meixner distribution appears as the spectral distribution of a spidernet [1], where the quantum probabilistic techniques are applied effectively [2]. It is well known that the spectrum of a graph is related to many properties of random walks. We will see that the spectral analysis is also applied effectively to showing the localization of Grover walks on spidernets [3].

[InaCombS] Fwd: [Dosen-ma] GraphMasters Workshop 2012

 

Dear all,

Saya forward-kan GRaphMasters Workshop 3.

best regards,

Edy.

Begin forwarded message:

Dear all,

KK Matematika Kombinatorika akan menyelenggarakan
GraphMasters Workshop, 18-19 Juli 2012. Informasi selengkapnya
dapat dilihat dibawah ini.

Kami ingin mengundang bapak/ibu/saudara yang berminat untuk
mengikuti workshop ini. Jumlah peserta dibatasi maksimum 30 orang.
Batas waktu pendaftaran 12 July 2012.

Terima kasih atas perhatiannya.

Salam hormat,
Suhadi

GraphMasters Workshop
ITB Bandung
July 18-19, 2012

The Combinatorial Mathematics Research Group, Faculty of Mathematics and
Natural Sciences, Institut Teknologi Bandung (ITB) in-cooperation with the
Indonesian Combinatorial Society organize a GraphMasters Workshop, July
18-19, 2012.

The aim of GraphMasters workshop is to bring together researchers in graph
theory and its applications at all levels (senior, junior, especially
graduate students) to study current problems of particularly theoretical
and practical interests. This forum is informal one, with no scheduled
presentations and mainly devoted to new research resulting from the
interactions among the participants.

In the discussions, all participants will be divided into small groups to
be able to share a common interest in a problem. All participants are
expected to actively take part in finding ways in solving the problems.
New joint-papers are expected to be the output and new collaboration are
the outcome.

All interested participants are welcome, around 30 participants are
expected. For registration, send an email to Suhadi
(suhadi@math.itb.ac.id) before 12 July 2012.

PROGRAM
GraphMasters is an informal workshop in which the participants are free to
interact with each other or to form new research groups. A schedule is
given only as a starting point for morning/afternoon sessions.

This schedule usually takes the form of participants volunteering to
briefly explain a topic or problem that they are interested in or stuck on!
And usually this attracts a spontaneous group of collaborators to tackle
the problem!


INVITED SPEAKERS
1. Mirka Miller, University of Newcastle, Australia
   Title: Open questions in the degree/diameter problem
2. Hilda Assiyatun, Institut Teknologi Bandung, Indonesia
   Title: Some problems on the locating-chromatic number of graphs
