Local Gaussian bounds on the non-destructive discrimination of two-mode squeezed states
Mi-Jung So, James Moran, Youngrong Lim +2
Typical measurement setups in quantum systems are destructive, meaning that states are irretrievably altered after measurement. In this work, we analyse non-destructive discriminat…
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…
Formulas for Mutually Orthogonal Quantum States in Two-Qubit Systems: Orthogonal Schmidt Decompositions
Yonghae Lee, Youngho Min, Sunghyun Bae +1
We present Schmidt decomposition formulas for mutually orthogonal two-qubit pure states and classify orthonormal sets based on their entanglement structure. First, we derive explic…
Classical algorithms for estimating expectation values in linear-optical circuits
Youngrong Lim, Changhun Oh
We present a classical algorithm for approximating the expectation values of observables in linear-optical circuits with arbitrary product input states, achieving additive-error ac…
Quantum secure learning with classical samples
Wooyeong Song, Youngrong Lim, Hyukjoon Kwon +5
Studies addressing the question "Can a learner complete the learning securely?" have recently been spurred from the standpoints of fundamental theory and potential applications. In…
Upper bounds on the quantum capacity for general attenuator and amplifier
Youngrong Lim, Soojoon Lee, Jaewan Kim +1
There have been several upper bounds on the quantum capacity of the single-mode Gaussian channels with thermal noise, such as thermal attenuator and amplifier. We consider a class…
