Pathways for entanglement based quantum communication in the face of high noise
Xiao-Min Hu, Chao Zhang, Yu Guo +10
Entanglement based quantum communication offers an increased level of security in practical secret shared key distribution. One of the fundamental principles enabling this security…
Experimental Entanglement Quantification for Unknown Quantum States in a Semi-Device-Independent Manner
Yu Guo, Lijinzhi Lin, Huan Cao +9
Using the concept of non-degenerate Bell inequality, we show that quantum entanglement, the critical resource for various quantum information processing tasks, can be quantified fo…
Simulating noisy variational quantum eigensolver with local noise models
Jinfeng Zeng, Zipeng Wu, Chenfeng Cao +4
Variational quantum eigensolver (VQE) is promising to show quantum advantage on near-term noisy-intermediate-scale quantum (NISQ) computers. One central problem of VQE is the effec…
A variational quantum algorithm for Hamiltonian diagonalization
Jinfeng Zeng, Chenfeng Cao, Chao Zhang +2
Hamiltonian diagonalization is at the heart of understanding physical properties and practical applications of quantum systems. It is highly desired to design quantum algorithms th…
Simulating Noisy Quantum Circuits with Matrix Product Density Operators
Song Cheng, Chenfeng Cao, Chao Zhang +4
Simulating quantum circuits with classical computers requires resources growing exponentially in terms of system size. Real quantum computer with noise, however, may be simulated p…
Fragility of quantum correlations and coherence in a multipartite photonic system
Huan Cao, Chandrashekar Radhakrishnan, Ming Su +6
Certain quantum states are well-known to be particularly fragile in the presence of decoherence, as illustrated by Schrodinger's famous gedanken cat experiment. It has been better…
