#那些听着特别有理的广告#
喜欢给人安利的人，自己也会非常容易吃安利。
以下是今天下午的事：
_带傻秋去洗澡驱虫，家门口去年年末新开的宠物店里，老板是猫奴特别会聊天，特别懂怎么照顾猫。我们分享了彼此家毛孩子的照片视频，老板给我喝了他新买的胶囊咖啡。

_傻秋洗了一个多小时，我跟老板聊了一个多小时。
...
_去的时候背着一只猫去，回来的时候背着一只猫两手拎着两个大袋子回来[跪了]

工作以有爱为最佳。
The golden rule is follow your passion and money will follow you.

spin up or spin down relative to the direction of the magnetic field.

Spin 1/2 objects like an electron have to be rotated around by 720 degrees instead of just the usual 360 in order to return to their original state. One way of visualizing how this could work via analogy is with the belt trick.

Bell state 泛化为 GHZ state
Understanding the entanglement of qubits requires an understanding of the Bell states.

Quantum computing
How to construct the matrix form of X-gate ? A is gate

inner product rule, which is ⟨ab|cd⟩ = ⟨a|c⟩ ⟨b|d⟩

可以看出对于给定的s，可以取“2s+1”个不同的值。例如：对于自旋为1/2的粒子，"sz"只能取两个不同的值，+1/2或-1/2。相应的量子态为粒子自旋分别指向+z或-z方向，一般我们把这两个量子态叫做"spin-up"和"spin-down"。

Unexpectedly, tomatoes that are common in our daily life are very useful in Spain.They have a festival related to tomatoes,Called the Tomato Festival,Also known as the Tomato Festival,On the last Wednesday of August each year,This is also one of the traditional festivals in the Spanish civilized world.Every time this holiday,The organizer will send several large trucks to bring tomatoes,Then gave an order,The revellers grabbed tomatoes and threw them at the "enemies" beside them,The rule of the game is that tomatoes must be crushed before they can be shot.After each scuffle,The entire city center will become a "sea of tomatoes",Then people will join another battle-sweeping the streets.it's here,Tomatoes bring more than just the joy of harvest,And the joy of carnival.
