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…
