Simultaneous Certification of Entangled States and Measurements in Bounded Dimensional Semi-Quantum Games
Xingjian Zhang, Qi Zhao
Certification of quantum systems and operations is a central task in quantum information processing. Most current schemes rely on a tomography with fully characterised devices, whi…
Experimental exploration of five-qubit quantum error correcting code with superconducting qubits
Ming Gong, Xiao Yuan, Shiyu Wang +19
Quantum error correction is an essential ingredient for universal quantum computing. Despite tremendous experimental efforts in the study of quantum error correction, to date, ther…
Universal and Operational Benchmarking of Quantum Memories
Xiao Yuan, Yunchao Liu, Qi Zhao +3
Quantum memory -- the capacity to store and faithfully recover unknown quantum states -- is essential for quantum-enhanced technology. There is thus a pressing need for operational…
One-shot Coherence Distillation with Catalysts
Senrui Chen, Xingjian Zhang, You Zhou +1
The resource theory of quantum coherence is an important topic in quantum information science. Standard coherence distillation and dilution problems have been thoroughly studied. I…
Detecting multipartite entanglement structure with minimal resources
You Zhou, Qi Zhao, Xiao Yuan +1
Recently, there are tremendous developments on the number of controllable qubits in several quantum computing systems. For these implementations, it is crucial to determine the ent…
Efficient and robust detection of multipartite Greenberger-Horne-Zeilinger-like states
Qi Zhao, Gerui Wang, Xiao Yuan +1
Entanglement is a key resource for quantum information processing. A widely used tool for detecting entanglement is entanglement witness, where the measurement of the witness opera…
Experimental Realization of Device-Independent Quantum Randomness Expansion
Ming-Han Li, Xingjian Zhang, Wen-Zhao Liu +12
Randomness expansion where one generates a longer sequence of random numbers from a short one is viable in quantum mechanics but not allowed classically. Device-independent quantum…
Randomness expansion secured by quantum contextuality
Mark Um, Qi Zhao, Junhua Zhang +6
The output randomness from a random number generator can be certified by observing the violation of quantum contextuality inequalities based on the Kochen-Specker theorem. Contextu…
