Classical simulation of a quantum circuit with noisy magic inputs
Jiwon Heo, Sojeong Park, Changhun Oh
Magic states are essential for universal quantum computation and are widely viewed as a key source of quantum advantage, yet in realistic devices they are inevitably noisy. In this…

Matrix product state approach to lossy boson sampling and noisy IQP sampling
Sojeong Park, Changhun Oh
Sampling problems have emerged as a central avenue for demonstrating quantum advantage on noisy intermediate-scale quantum devices. However, physical noise can fundamentally alter…

Classical algorithms for measurement-adaptive Gaussian circuits
Changhun Oh, Youngrong Lim
Gaussian building blocks are essential for photonic quantum information processing, and universality can be practically achieved by equipping Gaussian circuits with adaptive measur…
