Fast classical simulation algorithms for free-fermion dynamics with magic input
Jiwon Heo, Oliver Reardon-Smith, Michał Oszmaniec +2
The classical cost of simulating free-fermion (matchgate) circuits depends on both the input state and the computational task. We develop classical algorithms for circuits with non…

Efficient Learning of Fermionic Magic States under Free-Fermion Evolution
Jiwon Heo, Myeongjin Shin, Changhun Oh
We establish efficient learning for a family of fermionic magic states under unknown number-conserving free-fermion evolution. Each input block has a definite particle number and i…

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…
