Majorana zero modes and topological quantum computing based on Meissner effect and Abrikosov vortex
演讲人：刘鑫 [华中科技大学]时间：16:00-17:00, Oct 28, 2025 (Tue)地点：RM S327, MMW Building内容：Majorana zero modes (MZMs) exhibit non-Abelian braiding statistics, rendering them a cornerstone for topological quantum computing. A robust MZM platform demands a wide topological superconducting parameter space that facilitates experimental detection and control of MZMs and provides a promising de...

Generalized Planar and Toric Codes as High-Efficiency Quantum Memories
演讲人：陈昱安 [北京大学]时间： 16:00-17:00, Oct 21, 2025 (Tue)地点：RM S327, MMW Building内容：The Kitaev toric code remains a benchmark for fault-tolerant quantum computation, yet standard techniques for increasing its logical dimension—lattice surgery, punctures, or concatenation—incur substantial qubit overhead. I will present a unified construction and analysis framework that alleviates ...

Genuine quantum scars in many-body spin systems
演讲人： Andrea Pizzi [Trinity College, Cambridge] 时间： 10:00-11:00, Sep 17, 2025 (Wed)地点：RM 1-222, FIT Building内容：Chaos makes isolated systems of many interacting particles quickly thermalize and forget their past. While this picture applies to simple observables such as order parameters and correlators, it need not extend to more complex quantities like wavefunction amplitudes, that a...

General Approach to Error Detection of Bosonic Codes via Phase Estimation
演讲人： 金缘德 [中国科学院半导体研究所/中国科学院大学]时间： 10:00-11:30, Sep 12, 2025 (Fri)地点：RM S527, MMW Building内容：Quantum phase estimation (QPE) is an important algorithm in quantum information processing, designed to estimate the eigenvalues of a unitary operator, and it plays a significant role in quantum metrology. In our previous work [1], we have established a general framework...
