Space-Efficient Quantum Algorithm for Elliptic Curve Discrete Logarithms with Resource Estimation
时 间：10:30-12:00, May 12, 2026 (Tue)地 点：RM S327, MMW Building内容：Solving the Elliptic Curve Discrete Logarithm Problem (ECDLP) is critical for evaluating the quantum security of widely deployed elliptic-curve cryptosystems. Consequently, minimizing the number of logical qubits required to execute this algorithm is a key object. In implementations of Shor's algorithm, the space comple...

Exponential quantum advantage in processing massive classical data
时 间：10:00-11:30, May 8, 2026 (Fri)地 点： RM S527, MMW Building内容：Broadly applicable quantum advantage, particularly in classical data processing and machine learning, has been a fundamental open problem. In this work, we prove that a small quantum computer of polylogarithmic size can perform large-scale classification and dimension reduction on massive classical data by processing sa...

Beyond Bell: falsifying direct causation
时 间：14:00-15:00, Apr 27, 2026 (Mon)地 点： RM S327, MMW Building内容：According to Reichenbach's criterion, correlations may come through two structures: common cause, or direct causation. For the case of correlations obtained by measuring entangled systems, Bell famously excluded any explanation relying only on a common cause. A few years ago, we first intuited [1,2] and then finally pr...

2,400镱原子光镊阵列的高效率装载
时 间：13:00-15:00, Apr 21, 2026 (Tue)地 点：Seminar Room 2, 19th Floor, Tower C, TusPark内容：中性原子阵列已成为量子计算、量子模拟和量子精密测量的重要平台。其中，类碱土原子展现出长相干时间、高保真度量子门和擦除误差转化等独特优势，但其阵列规模长期落后于碱金属原子。我们在光镊阵列中成功俘获2400个镱-174原子，并实现了83.5(1)%的单原子增强装载效率，打破碱土金属原子光镊阵列规模纪录。我们进一步发现...

World Modeling from Reconstruction, Simulation and Action
时 间：13:00-15:00, Apr 21, 2026 (Tue)地 点：Seminar Room 2, 19th Floor, Tower C, TusPark内容：Building world models that internally represent how the world looks, evolves, and responds to actions is increasingly recognized as a foundation for embodied intelligence. As Vincent Sitzmann suggests, traditional vision tasks like 3D reconstruction, segmentation, and detection may ultimately serv...

Harnessing quantum physics for the next generation of continuously monitored sensors
演讲人：杨大猷 [中国科学技术大学]时 间：16:30-18:00, Apr 17, 2026 (Fri)地 点：RM 1-222, FIT Building内容：Continuous monitoring of driven-dissipative quantum optical systems provides key strategies for the implementation of quantum metrology, with prominent examples ranging from the gravitational wave detectors to the emergent driven-dissipative many-body sensors. Nevertheless, fundamental ...
