Harvard-quantum-initiative] Harvard Quantum Information Meeting

by Xun Gao

Dear all, This week will be the final "Harvard Quantum Information Group Meeting” this semester, which will be held on Thursday, December 1st at 4:30 pm in Jefferson 250. This week, Eric Anschuetz from MIT will talk. Title: Contextuality for Quantum Advantage Abstract: Quantum machine learning models have been widely studied in recent years, given their potential practical utility and recent results regarding their ability to efficiently express certain classical data. However, analytic results to date typically rely on assumptions and arguments from complexity theory. Due to this, there is little intuition as to the source of the expressive power of quantum neural networks or for which classes of classical data any advantage can be reasonably expected to hold. In this tutorial, I will discuss recent results (arXiv:2101.08354, arXiv:2209.14353) studying the relative expressive power between a broad class of machine learning models and a class of recurrent quantum models. I will discuss how the presence of quantum contextuality can be used to show an unconditional memory separation in the expressivity of quantum machine learning models. Additionally, I will discuss the implications of these techniques in showing quantum advantages on practical translation data sets. Here is the link of <https://calendar.google.com/calendar/u/0?cid=Y185MWI0YjdkMWE3YmJjYzkwODNlNT…>google calenda <https://calendar.google.com/calendar/u/0?cid=Y185MWI0YjdkMWE3YmJjYzkwODNlNT…>r for the next few meetings. The meeting is open to everyone at Harvard interested in quantum information, including those in condensed matter physics, AMO physics, high energy physics, computer science, chemistry, etc. The format includes weekly tutorials (by both external and internal speakers) of contemporary topics in quantum information and quantum computing, aimed for a broad scientific audience. We will also try to foster connections between different groups at Harvard which are interested in or involved with quantum information, and build a broader community. Hope to see you all there. If you would like to join the mailing list for this meeting, please e-mail harvardqimeeting(a)gmail.com <mailto:harvardqimeeting@gmail.com> which will add you.

Note about office hours and check-in

by Sule, Nishant V.

Hello everyone, Starting next week (week of Nov. 28th) I am going to have weekly office hours. The office hours are times when you can expect to find me in person to talk about anything (a question you might have, a second opinion on a course you might be thinking of, something that might be bothering you, something that you want to brainstorm, be a sounding board, you get the point…) You can of course, always reach out over Slack or email, but during the office hours you can just drop by. Below are the office hours times and locations. Please make a note on your calendar if that helps. Office hours When: Monday 10am–12:30pm, Where: MD 116 When: Tuesday 11am-1pm, Where: MD 116 I addition, I would like to meet each one of you individually for say no more than 20 mins, ideally by the end of this semester. Please use this Calendly link<https://calendly.com/nishantsule/20min> to sign-up for a slot that works for you. I’d prefer in-person meetings unless unavoidable, in which case Zoom could be an option. The goal for this short check in is just to gauge how things are going so far for you and get feedback on some general items. Hope you all have a nice Thanksgiving break!

[Harvard-quantum-initiative] Harvard Quantum Information Meeting

by Xun Gao

Dear all, This week will be the 8th "Harvard Quantum Information Group Meeting", which will be held on Thursday, November 17th at 4:30 pm in Jefferson 250. This week, Eugene Tang from MIT will give a tutorial first, then Aleksander Kubica from AWS center for quantum computing will give a talk. Title: Overview of Quantum Error-Correction (by Eugene) Abstract: In the first part of the talk, we will provide a tutorial overview of quantum error-correction. We will talk about quantum CSS codes, the homological view of the toric code, noise models, and the syndrome decoding problem. We will then talk about minimum-weight perfect matching (MWPM) decoding of the toric code, including how to handle the case of noisy syndrome measurements. This part of the talk will be intended for audiences with minimal familiarity with quantum error-correction with the goal of setting up for Alex's second part. Title: Single-shot quantum error correction (by Alex) Abstract: Fault-tolerant protocols and quantum error correction (QEC) are essential to building reliable quantum computers from imperfect components that are vulnerable to errors. Optimizing the resource and time overheads needed to implement QEC is one of the most pressing challenges. In this talk, I will introduce a new topological QEC code, the three-dimensional subsystem toric code (3D STC). I will explain how the 3D STC allows for single-shot QEC, i.e., reliable QEC with no time overhead even in the presence of measurement errors. Due to its high QEC threshold together with local parity checks of small weight, the 3D STC is particularly appealing for realizing fault-tolerant quantum computing. Based on A. Kubica, M. Vasmer, Nat. Commun. 13, 6272 (2022). Here is the link of <https://calendar.google.com/calendar/u/0?cid=Y185MWI0YjdkMWE3YmJjYzkwODNlNT…>google calenda <https://calendar.google.com/calendar/u/0?cid=Y185MWI0YjdkMWE3YmJjYzkwODNlNT…>r for the next few meetings.

[Harvard-quantum-initiative] HQI Joint Quantum Seminar - Prof. Jason Cong (UCLA)

by Harvard Quantum Initiative

Joint Quantum Seminar - Prof. Jason Cong Wednesday November 16, 2022 Pierce Hall 301 4:00 PM - 6:00 PM Title: “FPGAs, Real-Time Processing, and Quantum Computing” Abstract: An Field Programmable Gate Array (FPGA) is a programmable integrated circuits that one can customize in his/her office/lab to get a dedicated application-specific circuit for his/her own applications with much reduced processing latency and power consumption compared to general-purpose CPUs. In this talk, I shall start with a quick tutorial of the FPGA technology, including its architecture and design flow. Then, I shall give examples how FPGAs are used for real-time processing and control, including recent works on FPGA-based in-vivo calcium image processing and decoding and high-throughput real-time processing for Compact Muon Solenoid (CMS) detector in the Large Hadron Collider at CERN. Next, I shall discuss how FPGAs can be used in quantum computing, such as closed-loop feedback for stabilizing frequency fluctuations and state initialization for the superconducting qubits. Finally, I shall present our latest progress on high-level synthesis (HLS) that supports dataflow programming and latency-insensitive designs. Our goal is to facilitate researchers (e.g. everyone in the HQI community) to efficiently design FPGAs with no or little prior circuit design experience. Student presentation begins at 4:00 PM Refreshments begins at 4:15 PM Guest Presentation begins at 4:30 PM ---- SPEAKER BIO: JASON CONG is the Volgenau Chair for Engineering Excellence Professor at the UCLA Computer Science Department (and a former department chair), with joint appointment from the Electrical and Computer Engineering Department.
