Saving resources through repeat-until-success positive-operator-valued-measure measurements in quantum computation
Hefeng Wang, Sixia Yu, Hua Xiang
We present a quantum computation approach in which computation is guided by positive-operator-valuedmeasure (POVM) measurements following a given computation path in multisteps. In…

Quantum algorithm for PageRank computation through multistep quantum resonant transitions
Chuqing Wang, Hefeng Wang, Hua Xiang
We present a quantum algorithm for obtaining a quantum state that encodes the PageRank vector of the Google matrix through multistep quantum resonant transition (mQRT). In the algo…

A Practical Semi-Quantum Signature Protocol with Improved Eavesdropping Detection
Zengyu Pang, Hua Xiang
Semi-quantum signature (SQS) schemes aim to enable quantum signature functionality in scenarios where only a subset of participants possess full quantum capabilities, thereby impro…
