Improvement of quantum walk-based search algorithms in single marked vertex graphs
Xinying Li, Yun Shang
Quantum walks are powerful tools for building quantum search algorithms or quantum sampling algorithms named the construction of quantum stationary state. However, the success prob…
Faster quantum mixing of Markov chains in non-regular graph with fewer qubits
Xinyin Li, Yun Shang
Sampling from the stationary distribution is one of the fundamental tasks of Markov chain-based algorithms and has important applications in machine learning, combinatorial optimiz…
Entangled state generation via quantum walks with multiple coins
Meng Li, Yun Shang
Generation of entangled state is of paramount importance both from quantum theoretical foundation and technology applications. Entanglement swapping provides an efficient method to…
Generalized exceptional quantum walk search
Meng Li, Yun Shang
We mainly study exceptional configuration for coined quantum walk search. For searching on a two-dimensional grid by AKR algorithm, we find some new classes of exceptional configur…
Experimental realization of state transfer by quantum walks with two coins
Yun Shang, Meng Li
Quantum state transfer between different sites is a significant problem for quantum networks and quantum computers. By selecting quantum walks with two coins as the basic model and…
Quantum communication protocols by quantum walks with two coins
Yun Shang, Yu Wang, Meng Li +1
We introduce some new perfect state transfer and teleportation schemes by quantum walks with two coins. Encoding the transferred information in coin 1 state and alternatively using…
Pure state `really' informationally complete with rank-1 POVM
Yu Wang, Yun Shang
What is the minimal number of elements in a rank-1 positive-operator-valued measure (POVM) which can uniquely determine any pure state in -dimensional Hilbert space $\mathcal{H}…
New bounds of Mutually unbiased maximally entangled bases in C^d\otimes C^{kd}
Xiaoya Cheng, Yun Shang
Mutually unbiased bases which is also maximally entangled bases is called mutually unbiased maximally entangled bases (MUMEBs). We study the construction of MUMEBs in bipartite sys…
