Sample-Efficient Tomography of a Class of Mixed States with Extensive Entanglement and Magic
Pengcheng Liao, Quntao Zhuang
Full tomography of a generic many-qubit quantum state requires exponentially many copies, while suitable structural constraints can make reconstruction sample-efficient. Existing a…
Variational Quantum Transduction
Pengcheng Liao, Haowei Shi, Quntao Zhuang
Quantum transducers are critical for quantum interconnect, enabling coherent signal transfer across disparate frequency domains. Beyond material and device advances, protocol desig…
Complexity of quantum tomography from genuine non-Gaussian entanglement
Xiaobin Zhao, Pengcheng Liao, Francesco Anna Mele +2
Quantum state tomography, a fundamental tool for quantum physics, usually requires a number of state copies that scale exponentially with the system size, owing to the intricate qu…
Quantum-enhanced learning with a controllable bosonic variational sensor network
Pengcheng Liao, Bingzhi Zhang, Quntao Zhuang
The emergence of quantum sensor networks has presented opportunities for enhancing complex sensing tasks, while simultaneously introducing significant challenges in designing and a…
Optimal noisy entanglement testing for ranging and communication
Pengcheng Liao, Quntao Zhuang
Given a quantum system entangled with another system , the entanglement testing problem arises, prompting the identification of the system within a set of iden…
