Gluing Randomness via Entanglement: Tight Bound from Second Rényi Entropy
Wonjun Lee, Hyukjoon Kwon, Gil Young Cho
The efficient generation of random quantum states is a long-standing challenge, motivated by their diverse applications in quantum information processing tasks. In this work, we id…
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 while…
Fast pseudothermalization
Wonjun Lee, Hyukjoon Kwon, Gil Young Cho
Quantum resources like entanglement and magic are essential for characterizing the complexity of quantum states. However, when the number of copies of quantum states and the comput…
Pseudochaotic Many-Body Dynamics as a Pseudorandom State Generator
Wonjun Lee, Hyukjoon Kwon, Gil Young Cho
Quantum chaos is central to understanding quantum dynamics and is crucial for generating random quantum states, a key resource for quantum information tasks. In this work, we intro…
