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…

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…
