Approximating outcome probabilities of linear optical circuits
Youngrong Lim, Changhun Oh
Quasiprobability representation is an important tool for analyzing a quantum system, such as a quantum state or a quantum circuit. In this work, we propose classical algorithms spe…
Spoofing cross entropy measure in boson sampling
Changhun Oh, Liang Jiang, Bill Fefferman
Cross entropy (XE) measure is a widely used benchmarking to demonstrate quantum computational advantage from sampling problems, such as random circuit sampling using superconductin…
Information transmission with continuous variable quantum erasure channels
Changchun Zhong, Changhun Oh, Liang Jiang
Quantum capacity, as the key figure of merit for a given quantum channel, upper bounds the channel's ability in transmitting quantum information. Identifying different type of chan…
Optimal estimation of conjugate shifts in position and momentum by classically correlated probes and measurements
Kimin Park, Changhun Oh, Radim Filip +1
Multi-parameter estimation is necessary for force sensing due to simultaneous and nontrivial small changes of position and momentum. Designing quantum probes that allow simultaneou…
Quantum-inspired classical algorithm for molecular vibronic spectra
Changhun Oh, Youngrong Lim, Yat Wong +2
We have recently seen the first plausible claims for quantum advantage using sampling problems such as random circuit sampling and Gaussian boson sampling. The obvious next step is…
