Virtual Quantum Markov Chains
Yu-Ao Chen, Chengkai Zhu, Keming He +2
Quantum Markov chains generalize classical Markov chains for random variables to the quantum realm and exhibit unique inherent properties, making them an important feature in quant…
Enhancement of non-Stabilizerness within Indefinite Causal Order
Yin Mo, Chengkai Zhu, Zhiping Liu +2
In quantum computing, the nonstabilizerness of quantum operations is crucial for understanding and quantifying quantum speedups. In this study, we explore the phenomena of nonstabi…
Computable and Faithful Lower Bound on Entanglement Cost
Xin Wang, Mingrui Jing, Chengkai Zhu
Quantifying the minimum entanglement needed to prepare quantum states and implement quantum processes is a key challenge in quantum information theory. In this work, we develop com…
Optimal unilocal virtual quantum broadcasting
Hongshun Yao, Xia Liu, Chengkai Zhu +1
Quantum broadcasting is central to quantum information processing and characterizes the correlations within quantum states. Nonetheless, traditional quantum broadcasting encounters…
Limitations of Classically-Simulable Measurements for Quantum State Discrimination
Chengkai Zhu, Zhiping Liu, Chenghong Zhu +1
In the realm of fault-tolerant quantum computing, stabilizer operations play a pivotal role, characterized by their remarkable efficiency in classical simulation. This efficiency s…
