Full positivity bounds for anomalous quartic gauge couplings in SMEFT
Fu-Ming Chang, Zhuo-Yan Chen, Shuang-Yong Zhou
Electroweak boson scattering at the LHC provides a crucial avenue for probing physics beyond the Standard Model, particularly regarding deviations in quartic gauge couplings. We de…
Binarisation-loophole-free observation of high-dimensional quantum nonlocality
Jia-le Miao, Elna Svegborn, Zhuo Chen +7
Bell inequality tests based on high-dimensional entanglement usually require measurements that can resolve multiple possible outcomes. However, the implementation of high-dimension…
iSwitch: QEC on Demand via In-Situ Encoding of Bare Qubits for Ion Trap Architectures
Keyi Yin, Xiang Fang, Zhuo Chen +10
Recent advances in quantum hardware and error correction have paved the way for early fault-tolerant (EFT) quantum computing. We propose iSwitch, a hybrid system architecture for t…
Optimized trajectory unraveling for classical simulation of noisy quantum dynamics
Zhuo Chen, Yimu Bao, Soonwon Choi
The dynamics of open quantum systems can be simulated by unraveling it into an ensemble of pure state trajectories undergoing non-unitary monitored evolution, which has recently be…
Optimizing Circuit Reusing and its Application in Randomized Benchmarking
Zhuo Chen, Guoding Liu, Xiongfeng Ma
Quantum learning tasks often leverage randomly sampled quantum circuits to characterize unknown systems. An efficient approach known as "circuit reusing," where each circuit is exe…
Detecting entanglement and nonlocality with minimum observable length
Zhuo Chen, Fei Shi, Qi Zhao
Quantum entanglement and nonlocality are foundational to quantum technologies, driving quantum computation, communication, and cryptography innovations. To benchmark the capabiliti…
