[仿真]Microwave Simulation of Grover's Quantum Search Algorithm

An analog of a quantum search method, known as Grover's Algorithm, is modeled without entanglement on the macroscopic 9oA
.!4q  
level, using numerical simulation of microwave devices and methods. An array of microstrip annular-ring resonators simulates 1u0NG)*f  
a quantum bit array. An oracle that performs a test to determine which element in the array is the answer to the search ,zY!EHpx  
algorithm is provided by a microwave-frequency plane wave, modulated by a Gaussian pulse. A single annular ring with a #s'  
resonant frequency identical to the frequency of the incident pulse serves as the answer to the search. It is shown that the kKg%[zXS  
number of Gaussian pulses needed to identify the answer element is equal to the NN iterations predicted by the Grover ^atB

algorithm. The decay in a microwave-resonator element is used to show that the quantum dual - a spontaneous decay of the 1p9+c~4l:  
excited energy level of a quantum bit, also described as its decoherence - can be a serious obstacle to the development of )q+9_KUq
