Trade-off between Information Gain and Disturbance in Local Discrimination of Entangled Quantum States
Youngrong Lim, Minki Hhan, Hyukjoon Kwon
We establish an information gain-disturbance trade-off relation in local state discrimination. Our result demonstrates a fundamental limitation of local strategy to discriminate en…

Extending Classically Simulatable Bounds of Clifford Circuits with Nonstabilizer States via Framed Wigner Functions
Guedong Park, Hyukjoon Kwon, Hyunseok Jeong
The Wigner function formalism has played a pivotal role in examining the non-classical aspects of quantum states and their classical simulatability. Nevertheless, its application i…

Quantum error cancellation in photonic systems -- undoing photon losses
Adam Taylor, Gabriele Bressanini, Hyukjoon Kwon +1
Real photonic devices are subject to photon losses that can decohere quantum information encoded in the system. In the absence of full fault tolerance, quantum error mitigation tec…
