Shallow quantum circuit for generating extremely low-entangled approximate state designs
Wonjun Lee, Minki Hhan, Gil Young Cho +1
Random quantum states have various applications in quantum information science. We discover a new ensemble of quantum states that serve as an -approximate state -design whil…

Super-Polynomial Growth of the Generalized Persistence Diagram
Donghan Kim, Woojin Kim, Wonjun Lee
The Generalized Persistence Diagram (GPD) for multi-parameter persistence naturally extends the classical notion of persistence diagram for one-parameter persistence. However, unli…
