Fernando Brandao, California Institute of Technology
Boundary States and Entanglement Spectrum from Strong Subadditivity
In this talk I will consider quantum states satisfying an area law for entanglement (e.g. as found in quantum field theory or in condensed matter systems at sufficiently low temperature). I will show that both the boundary state and the entanglement spectrum admit a local description whenever there is no topological order. The proof is based on strong subadditivity of the von Neumann entropy. For topological systems, in turn, I'll show that the topological entanglement entropy quantifies exactly how many extra bits are needed in order to have a local description for the boundary state. This latter result is based on a recent strengthening of strong subadditivity.
Based on joint work with Kohtaro Kato (University of Washington)
John Cardy, University of California, Berkeley
Modular hamiltonians in 2d CFT
I enumerate the cases in 2d CFT when the modular hamiltonian (log of the reduced density matrix) may be written as an appropriate integral over the energymomentum tensor times a local weight. This includes known examples as well as new timedependent ones. In all these cases the entanglement spectrum is that of an appropriate boundary CFT. I point out the obstruction to the existence of such a result for more complicated bipartitions of the space. This is joint work with Erik Tonni.
Netta Engelhardt, University of California, Santa Barbara
Towards a Reconstruction of General Bulk Metrics
I will describe a procedure for reconstructing the metric of a general holographic spacetime (up to an overall conformal factor) from distinguished spatial slices  “lightcone cuts”  of the conformal boundary. This reconstruction can be applied to bulk points in causal contact with the boundary. I will also discuss a prescription for obtaining the lightcone cuts from divergences of correlators in the dual field theory.
Matthew Headrick, Brandeis University
A new perspective on holographic entanglement
The bynow classic RyuTakayanagi formula associates the entanglement entropy of a spatial region in a holographic field theory with the area of a certain minimal surface in the bulk. Despite its simplicity and beauty, this formula raises a number of stubborn conceptual problems. I will present a reformulation which does not involve the areas of surfaces. This reformulation leads to a picture of entanglement in the field theory being carried by Planckthickness "bit threads" in the bulk. I will argue that this picture helps to resolve a number of the conceptual difficulties surrounding the RT formula.
Renato Renner, ETH Zurich
An Extension of the Wigner’s Friend Gedankenexperiment
In this talk I consider the following principle that one may impose on any physical theory T:
"If an agent uses T to describe a system which includes another agent who herself uses T then no logical contradictions should arise.”
I then propose a gedankenexperiment, which can be regarded as an extension of the Wigner’s Friend experiment, to test whether this principle holds for quantum mechanics. The conclusion is that this is indeed the case for “plain" quantum theory, but that the principle is violated by many of its common interpretations and extensions.
Daniel Roberts, Massachusetts Institute of Technology
Holographic complexity by design
Douglas Stanford, Institute for Advanced Study
The SachdevYeKitaev model and AdS2/CFT1
The application of holography to fundamental problems in quantum gravity has been hindered by the lack of a solvable model. However, building on work by Sachdev and Ye, Kitaev has proposed a solvable QM system as a dual to an AdS2 black hole. I will discuss the model and its possible bulk interpretation.
Guifre Vidal, Perimeter Institute
Tensor Networks for Quantum Fields:
Conformal Invariance and Emergent de Sitter Space
The multiscale entanglement renormalization ansatz (MERA) is a tensor network that efficiently represents the ground state wavefunction of a lattice Hamiltonian. Similarly, its extension to the continuum, the continuous MERA [proposed by Haegeman, Osborne, Verschelde and Verstraete, Phys. Rev. Lett. 110, 100402 (2013), arXiv:1102.5524], aims to efficiently represent the vacuum state wavefunctional of a quantum field theory. In this talk I will first review MERA and cMERA, with emphasis on why we should care about these two constructions, including their conjectured connection to the AdS/CFT correspondence. Then, using the simplified context of the free boson CFT in 1+1 dimensions, I will discuss two new results: (1) the cMERA wavefunction, which has an explicit UV cutoff, is nevertheless invariant under the conformal group (but with modified Virasoro generators: the stress tensor is nonlocal at short distances); (2) cMERA can be regarded as an evolution in de Sitter space. Talk based on joint work with Qi Hu, in preparation.
There was a tremendous amount of interest for the “It from Qubit” summer school being hosted at Perimeter Institute from July 1829, 2016. As we were not able to accept everyone into the program, arrangements have been made for livestreaming, and satellite workshops have been established in some select locations. More information regarding these options is listed below:
Main Lectures: Live Streaming Setup and Chat
Perimeter will be livestreaming the conference talks to allow satellite schools and remote attendees to follow the proceedings  see the URL below. The Livestream service supports all Flash playing browsers.
Streaming and Chat URLs
http://perimeterinstitute.ca/itqubitsummerschool/livestreamsession1 (Main page)
http://perimeterinstitute.ca/itqubitsummerschool/livestreamsession2 (Secondary page)
The main page will live stream all lectures and seminars taking place in the Theatre, ie, at 9am, 11am and 5pm (Waterloo time)  see the Schedule. The secondary page will only be active for the 9am lecture on Monday July 18th, Tuesday July 19th and Wednesday July 20th and will show the lecture given in the Bob Room.
If you would like to submit questions through the Live Chat, we ask that you apply the following Etiquette:
 Introduce yourself  Start your comment with your name and location (eg, "Lenny Susskind, Stanford: I'd like to ask ..." so we know who you are.
 Be concise  keep comments or questions short so we have a chance to read and respond to them without a long delay.
 Avoid abbreviations  avoid abbreviations and acronyms unless they are standard physics conventions.
 Avoid followup questions, thanks or good byes  keep to a single comment or question to respect time constraints
If you have difficulties viewing the live stream, please, contact: Jeff Leithwood <jleithwood@perimeterinstitute.ca>
All lectures (including focus lectures) will be recorded and the recordings will be available on PIRSA at the URL below. Every effort will be made to have the recordings posted within a few hours of presentation
http://pirsa.org/C16003
Remote Participants
Remote participants will be able to both watch the live video feed and send questions and comments via the chat feature at the links above. Remote participants are also invited to consider the practice problems which will be posted to the conference website, as the school progresses. (Solution sets will also be provided in due course.)
Satellite Schools
The satellite schools will be organized at select locations to allow students view the lectures and work on the practice problems in a group. If you are interested in participating in one of the satellite schools, we kindly request that you contact the following individuals at the location most convenient for you. If you are interesting in organizing a new satellite school and have it advertised here, please contact Stephanie Mohl at smohl@perimeterinstitute.ca

Generally, the morning lectures will take place in the Mike Lazaridis Theatre on the 1^{st} floor. The first lecture begins at 9am and the second lecture, at 11am. Please ensure that you arrive promptly in order to guarantee a seat and to cause no disruption to the lecture. The lectures will also be shown in the Bob Room on the 4^{th} floor, in case the seating in the theatre reaches maximum capacity.
At 9am on the first three days of the conference, there will be an exception to the above arrangements and instead there will be two simultaneous lectures. The first will be in the Bob Room and will be directed at QI students interested in learning more about gravity and quantum field theory. The second will be in the Theatre and will be directed at HE students interested in learning about quantum information basics.
Summer School Problem Solving sessions:
Due to the number of students who will be participating in the “It from Qubit” summer school, it was necessary to hold the problem solving session in two separate rooms: the 2^{nd} Floor Bistro or the Space Room (on the 4^{th} floor). On the back of your nametag, you will see to which of these two rooms you have be assigned. Please go to the room indicated as there is a limited number of spaces in each room and the spaces have been set up based on your placement.
You will also see a coloured dot on the front of your nametag. A red dot indicates that our information was that your primary background was in Quantum Information whereas a blue dot indicates a High Energy background. Please, do not worry if you feel we have made an error in this assignment. Both of the rooms are arranged with tables for 8 students each. We are going to ask you to arrange yourselves so that each table seats (roughly) 4 QI students and 4 HE students. A few printed copies of the problem sets will be provided at each table. The problem sets can also be on the conference website. (Solutions will also be posted there in due course.)
Further we are encouraging the students to help each other in these sessions. So feel free to discuss the problems (as well as the morning’s lectures) in your group and seek advice from someone with a different background than yours. There will also be two tutors supervising each session and so you can also ask them when you get stuck. Each of the morning’s lecturers will also visit the problem solving sessions at some point in the afternoon and so again we encourage you to ask them about the problems (as well as the morning’s lectures).
Focus Lectures:
Two focus lectures have been scheduled for each day from 5–6pm; one in the Alice Room (3^{rd} floor) and one in the Bob Room (4^{th} floor). These are supplementary lectures which we hope will help provide a greater understanding of the material presented in the morning courses. Please feel free to attend which ever lecture you think you will benefit from the most. Advanced students should also feel free to attend the workshop seminar which will be taking place at the same time in the Theatre.
Final Note:
This summer school has been organized by the "It from Qubit" Simons Collaboration to promote communication and learning between the high energy physics and quantum information theory communities. Hence, we are catering to a very broad spectrum of students and we have arranged a diverse set of activities. The school is also being held concurrently with a research workshop of the "It from Qubit" Collaboration. However, you will simply not be able to attend all of the lectures, seminars and other activities that are taking place here at Perimeter in the next two weeks! You will have to make choices. So we are asking each of you to choose to participate in those activities that you think will maximally benefit your own learning. As a side note, let us add that all of the lectures and seminars will be recorded and should appear at http://pirsa.org/C16003 within a few hours of their completion.
Please, enjoy your stay here at Perimeter!

Tuesday Jul 26, 2016
the multiscale entanglement renormalization ansatz (MERA) is a tensor network that efficiently represents the ground state wavefunction of a lattice Hamiltonian. Similarly, its extension to the continuum, the continuous MERA [proposed by Haegeman, Osborne, Verschelde and Verstraete, Phys. Rev. Lett. 110, 100402 (2013), arXiv:1102.5524], aims to efficiently represent the vacuum state wavefunctional of a quantum field theory.
