Invitation to a relevant thesis seminar
|You are invited to come to the M.Sc. thesis seminar of the TA (Rotem) about QIP.|
M.Sc. Thesis Seminar by Rotem Liss
Time and Place: 18/04/2017 15:00 in Taub 601
Speaker: Rotem Liss
Title: Entanglement and Geometrical Distances in Quantum Information and Quantum Cryptography
Supervisor: Prof. T. Mor
The counter-intuitive features of Quantum Mechanics make it possible to solve problems and perform tasks that are beyond the abilities of classical computers and classical communication devices.
Entanglement is an important feature of quantum states, and it is important in quantum information, quantum communication, and quantum computing. In the main part of this talk, we provide a geometrical analysis of entanglement and separability for all the quantum mixed states that are of rank 2. For each rank-2 mixed state, we define its unique Bloch sphere (a geometrical representation of its "neighboring" states); we characterize those Bloch spheres into exactly five classes of entanglement and separability, give examples for each class, and prove that those are the only classes.
Quantum Key Distribution (QKD) protocols make it possible for two parties to share a secret random key (an impossible task in classical communication). Several important QKD protocols, including the first protocol of Bennett and Brassard (BB84), have their unconditional security proved against very powerful adversaries. In this talk, we discuss a slightly different protocol, named "BB84-INFO-z", and prove it secure against a broad class of attacks (the collective attacks). Moreover, we make use of a quantum geometrical distance (the "trace distance") to make our security proof more composable than similar security proofs of BB84.
The talk is self-contained and requires no prior knowledge of quantum information.
The talk will be given in English.
Final grades have been published
|We have published the final grades in the course and have submitted them to the secretaries.|
We apologize for the delay in publishing the grades.
Good luck in your studies.
Some additional messages
|The project-related work to be completed before each lesson (on Wednesday) is expected to be accomplished by Monday at 17:00, so that it can be checked by us and feedback can be given before or during the lesson; and is expected to be presented during the lesson.|
For example: the project-related work to be completed by the lesson of Wednesday 4/1/2017 is expected to be accomplished by Monday 2/1/2017 at 17:00 and to be presented during the lesson.
The two office hours of Rotem before the next lesson (Mondays, 26/12/2016 and 2/1/2017) will be given.
The next office hour of Tal (Wednesday 28/12/2016) is during Hanukkah vacation and therefore might not be given.
HW for next week and plan for the rest of the semester
|For the lesson next week (21/12/2016), each student should prepare a 15-20 minutes talk (not including the questions), presenting:|
1. A proposal for the wiki-project.
2. The work done so far for the project (and not for the side-issues).
3. The planned work to be accomplished until 4/1/2017 (how the project should look like at this stage).
4. The planned work to be accomplished until 18/1/2017 (finishing the project).
Then, questions and comments will be suggested by the other students, by the lecturer, and by the TA.
It is not necessary to use slides for the talks.
Today we will informally discuss those points and draft the talks together.
Until Monday (19/12/2016) at 23:59, each student should send an e-mail to the lecturer and to the TA, shortly explaining points 1+3+4.
Starting from 21/12/2016 (excluding Hanukkah vacation), work on the project is expected each week until 18/1/2017.
In each of the remaining lessons (4/1/2017, 11/1/2017, 18/1/2017), the students will present their work in the recent week, and their plans for the next week. In particular, the students will have to review the commitments of items 3+4 above and show how they have been accomplished. Projects should be finished until 18/1/2017.
The last lesson (25/1/2017) is kept for conclusions, feedback, discussion of changes and comments by other Wikipedians, and a last chance of presentations for the students who could not finalize their projects by January 18.
|Please bring laptops to all the lessons from now on.|
|Some amount of contributions to Wikipedia is expected each week.|
In addition, until the lesson of 30/11/2016, each student should add a reference to a QIP-related article.
HW to be completed until the lesson of 9/11/2016
|Slightly edit a Wikipedia article that you choose (doing a little more than just correcting a typo).|
HW to be completed until the lesson of 2/11/2016
|1. Create an account in the English Wikipedia, and send the user name by e-mail to both Tal and Rotem.|
2. Experiment with editing in your sandbox (link is available in the top line of the English Wikipedia, when logged in).
Please bring laptops to the next lesson (2/11/2016).
[The students who did not attend the first lesson should also read the first two parts ("Welcome" and "The Core") of the orientation for students in Wikipedia:
