The possible prospects for the improvement of the resolution and of the sensitivity in quantum-optics ex- periments are discussed as well as possible applications of quantum-optics methods for the solution of fundamen- tal physical problems.
The algorithm is based on the combination of quantum evolutionary algorithm(QEA) and ant colony system(ACS),a new algorithm,quantum ant colony algorithm(QACA) is proposed.The core is that Q-bit and quantum rotation gate adopted in QEA are introduced into ACS to represent and update the pheromone respectively,so it has better diversity and global search capacity.The ex-perimental result demonstrates that QACA can get better solutions to some traveling salesman problems(TSP) than the solutions given in existing bibliographer,it indicate that the algorithm is effective to solve TSP.
In this paper I will discuss the underlying philosophy of physics. A new definition of observer is presented, then the meaning of two words, ex-istence and reality, will be re-examined. With changes made for these three items a new philosophy emerges that allows an examination of the concepts of cause and effect, time, space and how mathematics enters into physics. The new philosophy suggests a structure of the universe that indicates both an understanding of the double slit ex-periment and a new approach to the quantization and root cause of gravitation.
