Efficient direct quantum state tomography using fan-out couplings
Jaekwon Chang, Guedong Park, Hyunseok Jeong +2
Characterizing quantum states is essential for validating quantum devices, yet conventional quantum state tomography becomes prohibitively expensive as system size grows. Direct to…
Sample- and Hardware-Efficient Fidelity Estimation by Stripping Phase-Dominated Magic
Guedong Park, Jaekwon Chang, Yosep Kim +2
Direct fidelity estimation (DFE) is a famous tool for estimating the fidelity with a target pure state. However, such a method generally requires exponentially many sampling copies…
Experimental Evidence-Based Sub-Rayleigh Source Discrimination
Saurabh U. Shringarpure, Yong Siah Teo, Hyunseok Jeong +5
We propose a Bayesian evidence-based inference framework based on relative belief ratios and apply it to discriminating between one and two incoherent optical point sources using s…
Low-Overhead Tailoring and Learning of Noise in Graph States
Guedong Park, Jinzhao Sun, Hyunseok Jeong
Graph and hypergraph states are important resource states for realizing universal quantum computation and diverse non-local physical phenomena. However, noise learning in such stat…
Error suppression in multicomponent cat codes with photon subtraction and teleamplification
Saurabh U. Shringarpure, Yong Siah Teo, Hyunseok Jeong
It is known that multiphoton states can be protected from decoherence due to a passive loss channel by applying noiseless attenuation before and noiseless amplification after the c…
Resource-efficient shadow tomography using equatorial stabilizer measurements
Guedong Park, Yong Siah Teo, Hyunseok Jeong
We propose a resource-efficient shadow-tomography scheme using equatorial-stabilizer measurements generated from subsets of Clifford unitaries. For -qubit systems, equatorial-st…
