Students have asked these similar questions
(a) Algebraically determine the output state |q3q2q1q0> (which is a 4-qubitvector in 16-dimensional Hilbert space). Show all steps of your calculations.
(b) Run a Qiskit code which implements the circuit and append threemeasurement gates to measure the (partial) output state |q2q1q0> (which is a 3-qubit vector in 8-dimensional Hilbert space).
this is for quantum soft dev class, you can use stuff like Deutsch Jozsa if u want
Write a C++ program that will count from 1 to 10 by 1. The default output should be
1, 2, 3, 4, 5, 6 , 7, 8, 9, 10
There should be only a newline after the last number. Each number except the last should be followed by a comma and a space.
To make your program more functional, you should parse command line arguments and change behavior based on their values.
Argument
Parameter
Action
-f, --first
yes, an integer
Change place you start counting
-l, --last
yes, an integer
Change place you end counting
-s, --skip
optional, an integer, 1 if not specified
Change the amount you add to the counter each iteration
-h, --help
none
Print a help message including these instructions.
-j, --joke
none
Tell a number based joke.
So, if your program is called counter
counter -f 10 --last 4 --skip 2
should produce 10, 8, 6, 4
Please use the last supplied argument. If your code is called counter,
counter -f 4 -f 5 -f 6
should count from 6.
You should count from first to last inclusively.…
