. (a) Draw the basic setup for quantum key distribution.

(b) Explain the “intercept-resend” attack that Eve can attempt (draw a simple figure).

(c) Explain how this attack is thwarted by the quantum key distribution protocol. How can Eve’s attack be detected?

(d) What does the security of quantum key distribution rely on fundamentally?

1. Explain on the basic operation of the n-channel JFET. Draw the drain characteristics or output characteristics of the mentioned JFET type and denote the important parameters on the graph 2. Explain why the JFET is called a unipolar device. Your explanation must be based on the n-channel or p-channel device which is biased to operate as an amplifier 3. A JFET amplifier has a load resistance, RL= 500 kΩ. Find the ac drain resistance, rd if the amplification factor,...

Define sampling distribution. b. Explain why the spread (variance) of a sampling distribution for estimating a mean would be smaller than the spread (variance) of the whole population. c. Discuss what happens to the shape AND spread of a sampling distribution as sample size (n) is increased. d.Explain why it is essential that the sampling distribution be normally distributed (or t-distributed) in order to do the statistical inference procedures we use in Chapters 9, 10 and 11.
