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…
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…
Gaussian boson sampling at finite temperature
Gabriele Bressanini, Hyukjoon Kwon, M. S. Kim
Gaussian boson sampling (GBS) is a promising candidate for an experimental demonstration of quantum advantage using photons. However, sufficiently large noise might hinder a GBS im…
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…
Estimating Entanglement Entropy via Variational Quantum Circuits with Classical Neural Networks
Sangyun Lee, Hyukjoon Kwon, Jae Sung Lee
Entropy plays a crucial role in both physics and information science, encompassing classical and quantum domains. In this work, we present the Quantum Neural Entropy Estimator (QNE…
Gaussian boson sampling with click-counting detectors
Gabriele Bressanini, Hyukjoon Kwon, M. S. Kim
Gaussian boson sampling constitutes a prime candidate for an experimental demonstration of quantum advantage within reach with current technological capabilities. The original prop…
