"An Introduction to Quantum Error Correction III"

Time: 15:30

Room: MC 107

Quantum Error Correction (QEC) serves as one of the most important fields, opening pathways to harness the true power of quantum computing. While quantum computing holds potential, this potential cannot be realized without ways to guarantee the stability and reliability of qubits, which are inherently prone to errors. To address this challenge, I will begin by exploring the origins of error correction, where early methods ensured reliable data transmission without fear of complete loss. From there, I will discuss the challenges of bridging classical and quantum error correction techniques. Finally, I will introduce stabilizer codes, one of the most promising class of codes in QEC. In future talks, I will build on this foundation to explore more advanced stabilizer codes, including topological codes.

"An introduction to $RO(G)$-graded cohomology theories"

Time: 09:30

Room: MC 108

n this talk, we will give an introduction to $RO(G)$-graded cohomology, which, in a certain sense, extends Bredon cohomology.

Graduate Seminar

Speaker: Siyuan Yu (Western)

"The symplectic embeddings of closed balls into the complex projective plane $\mathbb{C}P^2$"

Time: 15:30

Room: MC 108

In this presentation, we investigate the embeddings of five disjoint closed balls into the complex projective plane $\mathbb{C}P^2$. In 1985, Gromov found a new symplectic invariant called Gromov's invariant by studying the embedding of closed balls into a cylinder. This ground-breaking result opens a new era of the research of symplectic geometry. In this presentation, we explore the relationship between the homotopy type of the space of symplectic embeddings and the configuration space of $\mathbb{C}P^2$, focusing on the case of five balls.
