Description

technical field

[0001] The invention relates to the fields of semiconductor integrated optics technology and quantum information science, in particular to an integrable quantum device based on photonic crystals. Background technique

[0002] Quantum information science is an emerging discipline that uses quantum effects to process and transmit information. As the core of quantum information processing, quantum computing has gradually attracted widespread attention from the idea of ​​quantum computer proposed by Feynman et al. to the quantum Shor algorithm. The classical algorithm based on classical random walk has been very mature and widely used, but there are only a handful of existing quantum algorithms, and the construction of a complete quantum algorithm has become the key to realizing large-scale quantum computing and quantum computers. In the 1990s, people began to study quantum walks, began to use quantum walks to construct new quantum algorithms, and also used quan...
