$\begingroup$ My question is how to get $\frac{\pi}{4} (1+\frac{|\Delta \theta|}{\theta})$? $\endgroup$

$\begingroup$ @C.C: the $|\Delta \theta|$ term is used in the case of Grover search when its used for $k$ items. The phase estimation algorithm introduces this error $|\Delta \theta|$, in estimating $\theta$, which then is passed to a Grover Search(I dont have the N&C up front), but the $k$ item Grover Search application uses, the Phase Estimation algorithm before the Grover Search to get the good states. $\endgroup$

create code fences with backticks ` or tildes ~
```
like so
```
add language identifier to highlight code
```python
def function(foo):
print(foo)
```
put returns between paragraphs
for linebreak add 2 spaces at end
_italic_ or **bold**
indent code by 4 spaces
backtick escapes `like _so_`
quote by placing > at start of line
