Coherent-disorder-driven complexity transitions in a quantum-advantage architecture
Sung-Bin B. Lee, Chae-Yeun Park, Changhun Oh +1
While decoherence is known to erode classical hardness in quantum random sampling, the impact of coherent spatial disorder remains an open question. We study a square-lattice insta…
Scalable projected entangled-pair state representation of random quantum circuit states
Sung-Bin B. Lee, Hee Ryang Choi, Daniel Donghyon Ohm +1
Classical simulation of a programmable quantum processor is crucial in identifying the threshold of a quantum advantage. We demonstrate the simple update of projected entangled-pai…
Entanglement switching via mobility edges in a quasiperiodic chain
YouYoung Joung, Junmo Jeon, SungBin Lee
We propose quasiperiodic chains with tunable mobility edge physics, as a promising platform for engineering long-range quantum entanglement. Using the generalized Aubry-André mode…
Interaction tuned pattern-selective superconductivity: Application to the dodecagonal quasicrystal
Junmo Jeon, SungBin Lee
Quasicrystals exhibit superconductivity under the unique interplay of long-range order and strong inhomogeneity, distinguishing them from both crystalline and amorphous systems. Un…
Reallocation of Nonlocal Entanglement in Incommensurate Cold Atom Arrays
Jemin Park, Junmo Jeon, SungBin Lee
Cold atom arrays in optical lattices offer a highly tunable platform for exploring complex quantum phenomena that are difficult to realize in conventional materials. Here, we inves…
Hidden hyperspace geometry and long-distance quantum coupling
Junmo Jeon, SungBin Lee
Most periodic systems are governed by short-range interactions as long-range interactions in these systems diminish uniformly. In this letter, however, we demonstrate that this is…
