Heralded high-dimensional module-based quantum computation
Xiao Zhang, Wen-Qiang Liu, Hai-Rui Wei
Parity measurements have been explored as building blocks for preparing and discriminating entangled states, as well as for implementing quantum computation. We first develop two a…
Effective schemes for fusion of hyperentangled W states
Wen-Xiu Zhang, Wen-Qiang Liu, Hai-Rui Wei
Hyperentangled states are fascinating resources in quantum information processing as they can significantly increase the channel capacity and enhance noise resistance. We explore a…
Remote state preparation of single-partite high-dimensional states in complex Hilbert spaces
Jun-Hai Zhao, Si-Qi Du, Wen-Qiang Liu +2
High-dimensional quantum systems offer a new playground for quantum information applications due to their remarkable advantages such as higher capacity and noise resistance. We pro…
Efficient and deterministic high-dimensional controlled-swap gates on hybrid linear optical systems with high fidelity
Gui-Long Jiang, Jun-Bin Yuan, Wen-Qiang Liu +1
Implementation of quantum logic gates with linear optical elements plays a prominent role in quantum computing due to the relatively easier manipulation and realization. We present…
Deterministic generation of multi-qubit entangled states among distant parties using indefinite causal order
Wen-Qiang Liu, Hai-Rui Wei
Quantum entanglement plays an irreplaceable role in various remote quantum information processing tasks. Here we present protocols for generating deterministic and heralded -qub…
