In completing the IBM task, you measured the correlation function \( D\left(\theta_{1}, \theta_{2}\right) \) and the CHSH sum \( \Sigma_{\text {Expt }}=D\left(\theta_{1}, \theta_{2}\right)+D\left(\theta_{1}, \theta_{2}^{\prime}\right)+D\left(\theta_{1}^{\prime}, \theta_{2}\right)-D\left(\theta_{1}^{\prime}, \theta_{2}^{\prime}\right) \) of the two qubit state \[ |\Phi\rangle_{-}=\frac{1}{\sqrt{2}}(|01\rangle-|10\rangle) . \] In answering this question, you will describe how you designed and implemented circuits to comlpete the task. (a) Using a diagram, describe the circuit you have designed in the IBM-Q task to implement a measurement of \( |\Sigma| \) used to test the CHSH inequality (Book 1, Equation 12.56). (b) How did your circuit create the Bell state of Equation (1)? (c) How did you implement the rotation of the qubits prior to the measurement of \( D\left(\theta_{1}, \theta_{2}\right) \) ? How does this correlation measurement differ from the experiment described in chapter 12 ? (d) What tests did you make on your circuit prior to running the experiment on the quantum computer?

Blank 1 are sources of microorganisms, or areas that can harbour Blank 2. Some common sources include humans, plants, animals and the Blank 3; however Blank 4 are the most common reservoirs, and can spread Blank 5 from one person to another. Insects can be reservoirs by carrying Blank 6 like malaria and west nile virus. Reservoirs are often found in the hospital in such areas as Blank 7 bags, and wound Blank 8.

Consider a control system described by the following state variable model $\dot{x}(t) = Ax(t) + Bu(t)$ $y(t) = Cx(t) + Du(t)$ with $A = \begin{bmatrix} -k_1 & k_2 \ -k_1 & -k_2 \end{bmatrix}$, $B = \begin{bmatrix} k_1 \ k_1 \end{bmatrix}$, $C = \begin{bmatrix} 1 & 1 \ 0 & 1 \end{bmatrix}$ and $D = \begin{bmatrix} 0 \ 0 \end{bmatrix}$ (d) For another system with the following characteristic question $\Delta(s) = s^3 + ks^2 + ks + 8 = 0$ Determine the range of $k$ to make the system stable using Routh-Hurwitz criterion.

There are few dragons left in the Kingdom of Lidd, and they have been put on the endangered species list. There are two types of dragons in Lidd. The first type have reasoned that devouring domestic animals and humans is, in the long run, not healthy for dragons. They are known as RATIONALS. The second type of dragons however, are reluctant to give up their traditional ways and still feed on animals and humans. They are known in Lidd as PREDATORS. The King of Lidd has decreed that the RATIONAL dragons shall be protected. Any Knight caught slaying a RATIONAL dragon will spend the rest of his days in the dungeon. However, if a Knight kills a PREDATOR, he will be rewarded with a pot of gold. Now you need to know that in addition to being RATIONALS or PREDATORS, dragons in Lidd are of two different colors related to their veracity. GRAY RATIONAL dragons always tell the truth, RED RATIONAL dragons always lie. On the other hand, RED PREDATORS always tell the truth while GRAY PREDATORS always lie. To make matters worse, all the dragons from the neighboring country of Wonk have been driven out of their land into the kingdom of Lidd. It is easy to tell a dragon from Wonk because they are all BLUE. But a dragon from Wonk can either be a RATIONAL (and thus be protected by the King's decree) or a PREDATOR but ALL dragons from Wonk ALWAYS lie. So to help a Knight on his quest, it would help to know the color of the dragon. However, there is an affliction that affects every person in Lidd: they are colorblind. To them, ALL dragons look gray. A knight looking for a PREDATOR to slay runs into three dragons. The Knight asks them about each of their type and color. This is how they responded: A. If asked, B would claim that C is a PREDATOR. I am GRAY. B is RATIONAL. B. If asked, C would claim that A is a RATIONAL. C is RED. C. If asked, A would claim that B is RED. A is GRAY. What color and type is each dragon? Be sure to show ALL of your work!!
