QC WORKSHOP 18: Quantum Simulation Using Atoms and Ions

Posted on by daiweizhu

在过去的二十年里，用于研究多体系统的量子模拟和计算方法发展出了两类互补的方案。自上而下的方案通过对多粒子体系进行全局相互作用来模拟匀质体系。自下而上的方案通过整合多个可被高精度控制的粒子来构建大型系统。本次报告将介绍属于自上而下方案的玻色-爱因斯坦凝聚体量子模拟系统和属于自下而上方案的离子阱量子计算系统。在介绍技术细节的基础上，我们将进一步讨论应用这些体系来研究多种物理问题。

Quantum Simulation and computation on many-body systems has branched to two complementary strategies over the last two decades. The top-down strategy uses ensembles of many particles with control over global interactions, where the granular details can be ignored and the ensemble can be treated as a smooth medium. The bottom-up strategy uses high-fidelity control over individual particles and builds large many-body systems by assembling them together. In this talk, I will talk about both approaches with Bose-Einstein condensates in the top-down approach and trapped ions in the bottom-up approach. Building on the interacting atomic quantum system, we will talk about investigating interesting physics ranging from condensed matter to cosmology, such as quantum phase transition, spin domain confinement, many-body localizations and even Unruh radiations.

主讲人介绍： Dr. Lei Feng works on quantum simulation and quantum computing at Duke University. His current postdoctoral research focuses on building a new generation of programmable quantum computing platform using trapped Yb ions. Lei got his Ph.D. in physics from the University of Chicago on quantum simulation using ultra-cold neutral atoms, where Bose-Einstein Condensation is used to study phase transitions and matter-wave radiations. He is also a winner of Sidney Nagel Prize for Creativity in Research and the OCPA Outstanding Dissertation Award.

FinQ Quantum Algorithm Journal Club

Posted on by Leon

Having a huge algorithm knowledge reservoir is crucial to scientists trying to develop new algorithms or apply algorithms to real-world problems. The goal of this journal club is to supercharge the algorithm knowledge of participating members. 

Format:

Each session will include a 25-minute presentation followed by a 20-minute discussion. Each presentation should cover the “what, how, why” aspects of the algorithm: what does the algorithm do; How does the algorithm work; why is this algorithm in any sense better than its classical counterpart. Such three aspects should be introduced in an intuitive but self-consistent approach. Mathematical rigorousness is not required.

All the participants will take turns (signup-based) presenting papers. For our first-round cohort, we limit our discussion group to 12 people for effective communication. We will close registration once the limit is reached.

The first two sessions will be held by our core members Daiwei Zhu and Yue Sun. Time to be determined and will be announced to participating members. Register now if you are interested!

FinQ Case Study Series #1

Posted on by syzq

Aircraft Loading Optimisation with QUBO

Recently, Airbus announced their winner to The “Airbus Quantum Computing Challenge” (AQCC): the team Machine Learning Reply (MLR). In the fifth challenge — “Aircraft Loading Optimisation”, they formulated the problem and its constraints into cost functions in the form of Quadratic Unconstrained Binary Optimization (QUBO) problems. These cost functions are compatible with quantum annealers, as well as other hybrid classical-quantum optimization algorithms such as Quantum Approximate Optimization Algorithm (QAOA). Then they benchmarked the model on different solvers to evaluate the performances and capabilities of current technologies. 

In our case study, we will reimplement MLR’s approach in Python. Then, we can think of ways to improve their method, such as adding additional constraints and features. 

We expect that most participants would finish their assignments within 8 weeks, with a 4-hour weekly commitment and one 1-hour meeting biweekly. We will host an orientation / kick-off on October 16, 2021 and the session will conclude on December 11, 2021.

Participants would work together in groups of 3 or less. In this session, we plan to have a maximum of 3 groups.

How to register?

Registration details will be shared in WeChat group. Please add FinQ’s official account to join our WeChat groups.
