This slide is to learn English and presentation for me.
So, It might have some mistakes.
1.1 Social background
1.2 Whai is Quantum Annealing ?
1.3 Purpose of Quantum Annealing
1.4 How to solve the optimization problem
transistor’s scale Moore's law : The number of transistors doubles every two years. However, It is becoming difficult to make the transistor small. ◦ Problem 2 : The increase in power consumption IT consumes 10% of the total electricity generation in the world. Especially the server uses huge amount of power. 4
small chips. Supercomputer K (京) 's power consumption is about 12 MW. On the other hand, the power consumption of the D-wave quantum annealing machine is about 20 kW. 5 Quantum annealing is an ecological computer.
bits are always coupled to each other. Because noise acts on the entire system, it is smaller than it works individually. 7 1.2 What is Quantum Annealing Quantum Annealing is easy to operate stably. http://obeidlab.blogspot.com/2011/06/ising-model-quantum-mechanics-and-very.html
model belongs to the combinatorial optimization problem. Each Ising spin takes two values of ± 1. So, the total number of combinations is 2. 10 1.4 How to solve the optimization problem https://www.zaikei.co.jp/photo/237081.html
