Quantum Walk Search
In the context of quantum computing, the quantum walk search is a quantum algorithm for finding a marked node in a graph. The concept of a quantum walk is inspired by classical random walks, in which a walker moves randomly through a graph or Lattice graph, lattice. In a classical random walk, the position of the walker can be described using a probability distribution over the different nodes of the graph. In a quantum walk, on the other hand, the walker is represented by a quantum state, which can be in a Quantum superposition, superposition of several locations simultaneously. Search algorithms based on quantum walks have the potential to find applications in various fields, including Mathematical optimization, optimization, machine learning, cryptography, and Network analysis (electrical circuits), network analysis. The efficiency and probability of success of a quantum walk search depend heavily on the structure of the Feasible region, search space. In general, quantum walk sea ...

Quantum Computing
A quantum computer is a computer that exploits quantum mechanical phenomena. On small scales, physical matter exhibits properties of wave-particle duality, both particles and waves, and quantum computing takes advantage of this behavior using specialized hardware. Classical physics cannot explain the operation of these quantum devices, and a scalable quantum computer could perform some calculations Exponential growth, exponentially faster than any modern "classical" computer. Theoretically a large-scale quantum computer could post-quantum cryptography, break some widely used encryption schemes and aid physicists in performing quantum simulator, physical simulations; however, the current state of the art is largely experimental and impractical, with several obstacles to useful applications. The basic unit of information in quantum computing, the qubit (or "quantum bit"), serves the same function as the bit in classical computing. However, unlike a classical bit, which can be in ...
