报告提纲

Quantum simulators are engineered devices controllably designed to emulate complex and classically intractable quantum systems. A key challenge lies in certifying whether the simulator is truly mimicking the Hamiltonian of interest. However, neither classical simulations nor quantum tomography are practical to address this task because of their exponential scaling with system size. Therefore, developing novel certification techniques, suitable for large systems, is highly desirable. Here, in the context of fermionic spin-based simulators, we propose a global many-body spin to charge conversion scheme, which crucially does not require local addressability. A limited number of charge configuration measurements performed at different detuning potentials along a spin chain allow to discriminate the low-energy eigenstates of the simulator. This method, robust to charge decoherence, opens the way to certify large spin array simulators as the number of measurements is independent of system size and only scales linearly with the number of eigenstates to be certified. 

个人简介

Professor Abolfazl Bayat got his PhD from Sharif University of Technology in Iran in 2008 on the subject of "quantum state transfer in spin chains" under the supervision of Professor Vahid Karimipour. After that, he continued his research as a postdoc in the groups of Professor Sougato Bose at University College London (2008-2011) and Professor Martin Plenio at University of Ulm (2011-2013). He then joined the University College London on a 5-year senior position within the EPSRC funded program grant of "nano-electronic based quantum technologies", led by Professor Mike Pepper. In 2017, he got a 1000-talent youth professorship from the Chinese government with which he has started his group at the University of Electronic Science and Technology of China (UESTC) in Chengdu. Professor Bayat has also achieved Sichuan Talent fellowship in 2018.

会议简介

会议题目：2020 International Workshop on Quantum Information, Quantum Computing and Quantum Control会议时间：2020-01-02会议地点：上海主办方：上海大学
Quantum computing and quantum information processing make use of quantum systems and their non-classical properties as computational resources to outperform their classi cal counterparts. It is expected that a quantum computer solves computationally hard tasks for a classical computer, such as prime-number factorization of a large number and combinatorial problems, in a practical time. Many scientists, including mathematicians, physicists and computer scientists, are working toward physical realization of a practical quantum computer. In this workshop, we discuss these topics and related subjects including quantum control to facilitate our mutual understanding of these subject.
