Deterministic loading and phase shaping of microwaves onto a single artificial atom

W. -J. Lin, Y. Lu, P. Y. Wen +12

Loading quantum information deterministically onto a quantum node is an important step towards a quantum network. Here, we demonstrate that coherent-state microwave photons, with a…

Hybrid quantum-classical classifier based on tensor network and variational quantum circuit

Samuel Yen-Chi Chen, Chih-Min Huang, Chia-Wei Hsing +1

One key step in performing quantum machine learning (QML) on noisy intermediate-scale quantum (NISQ) devices is the dimension reduction of the input data prior to their encoding. T…

Discrimination of quantum states under locality constraints in the many-copy setting

Hao-Chung Cheng, Andreas Winter, Nengkun Yu

We study quantum hypothesis testing between orthogonal states under restricted local measurements in the many-copy scenario. For testing arbitrary multipartite entangled pure state…

Phase Analysis on the Error Scaling of Entangled Qubits in a 53-Qubit System

Wei-Jia Huang, Wei-Chen Chien, Chien-Hung Cho +6

We have studied carefully the behaviors of entangled qubits on the IBM Rochester with various connectivities and under a "noisy" environment. A phase trajectory analysis based on o…

On the Compressed-Oracle Technique, and Post-Quantum Security of Proofs of Sequential Work

Kai-Min Chung, Serge Fehr, Yu-Hsuan Huang +1

We revisit the so-called compressed oracle technique, introduced by Zhandry for analyzing quantum algorithms in the quantum random oracle model (QROM). To start off with, we offer…

Full-polaron master equation approach to dynamical steady states of a driven two-level system beyond the weak system-environment coupling

Chien-Chang Chen, Thomas M. Stace, Hsi-Sheng Goan

We apply a full-polaron master equation and a weak-coupling non-Markovian master equation to describe the steady-state time-averaged properties of a driven two-level system, an ele…
