Classical Simulation of Lossy Gaussian Boson Sampling beyond Square-Root Regime
Youngrong Lim
Photon loss makes Gaussian boson sampling easier to simulate classically. A standard approach replaces the lossy input by classical light, and it stays accurate while the mean numb…
Polynomial Separation between One-Way and Two-Way LOCC in Discrimination of Maximally Entangled States
Youngrong Lim
One-way local operations and classical communication (LOCC) can fail to distinguish four orthogonal maximally entangled states in every local dimension . We show that every…
Ultimate Information Rate for Quantum Sensing under Multilevel Relaxation
Changhun Oh, Seok Hyung Lie, Youngrong Lim
We determine the ultimate information rate of a relaxing multilevel quantum sensor under unrestricted adaptive control and construct an explicit strategy that attains it. We consid…
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…
Quantum Circuit Representation of Combinatorial Matrix Functions
Minhyeok Kang, Gwonhak Lee, Youngrong Lim +1
Permanents, hafnians, and loop-hafnians are combinatorial matrix functions closely related to perfect matchings in graphs. These matrix functions arise in the quantum amplitudes of…
