Sharing EPR steering between sequential pairs of observers
Qiao-Qiao Lv, Jin-Min Liang, Zhi-Xi Wang +1
The recycling of quantum correlations has attracted widespread attention both theoretically and experimentally. Previous works show that bilateral sharing of nonlocality is impossi…
Assisted quantum simulation of open quantum systems
Jin-Min Liang, Qiao-Qiao Lv, Zhi-Xi Wang +1
Universal quantum algorithms (UQA) implemented on fault-tolerant quantum computers are expected to achieve an exponential speedup over classical counterparts. However, the deep qua…
Unified multivariate trace estimation and quantum error mitigation
Jin-Min Liang, Qiao-Qiao Lv, Zhi-Xi Wang +1
Calculating the trace of the product of -qubit density matrices (multivariate trace) is a crucial subroutine in quantum error mitigation and information measures estimation.…
Improved iterative quantum algorithm for ground-state preparation
Jin-Min Liang, Qiao-Qiao Lv, Shu-Qian Shen +3
Finding the ground state of a Hamiltonian system is of great significance in many-body quantum physics and quantum chemistry. We propose an improved iterative quantum algorithm to…
Revealing hidden standard tripartite nonlocality by local filtering
Qiao-Qiao Lv, Jin-Min Liang, Zhi-Xi Wang +1
Quantum nonlocality is a kind of significant quantum correlation that is stronger than quantum entanglement and EPR steering. The standard tripartite nonlocality can be detected by…
An alternative framework for quantifying coherence of quantum channels
Shi-Yun Kong, Ya-Juan Wu, Qiao-Qiao Lv +2
We present an alternative framework for quantifying the coherence of quantum channels, which contains three conditions: the faithfulness, nonincreasing under sets of all the incohe…
Quantum Information Masking in Non-Hermitian Systems and Robustness
Qiao-Qiao Lv, Jin-Min Liang, Zhi-Xi Wang +1
By studying quantum information masking in non-Hermitian quantum systems, we show that mutually orthogonal quantum states can be deterministically masked, while an arbitrary set of…
Tighter Constraints of Multipartite Systems in terms of General Quantum Correlations
Jin-Hong Hao, Ya-Ya Ren, Qiao-Qiao Lv +2
Monogamy and polygamy relations characterize the quantum correlation distributions among multipartite quantum systems. We investigate the monogamy and polygamy relations satisfied…
