ISQS 2340 Exam 3 Questions and
Answers | 100% Pass


In quantum computing, "A" is represented as what combination of numbers as

explained to the child? - ✔️✔️Correct-01000001


When the woman is explaining to the teenager, she uses the analogy of the giant penny

and deciding whether it is heads or tails whilst spinning on its side. What property of

quantum computing is she describing in the use of this analogy? - ✔️✔️Correct-

superposition

Describe the property of "entanglement" as you understand it based off of how the

woman explained it to the teenager. - ✔️✔️Correct-taking two independent occurrences

and causing one to subsequently mimic the other

-very hard to undo an entanglement

-after entanglement, even if tested at the exact same time, the two occurrences would

still be exactly correlated

What name does the woman give the machine when talking to the teenager? -

✔️✔️Correct-dilution refrigerator

What does the dilution refrigerator do? - ✔️✔️Correct-a device used to cool quantum

chips to a temperature cold enough that superposition and entanglement can be

created through cubits without the information being lost to the environment

What is one of the things the woman says quantum computers can be used for when

she talks to the teenager? - ✔️✔️Correct-simulating chemical bonding

How do the "levels" work on a quantum computer as described to the undergrad

student? - ✔️✔️Correct-the levels get colder as you go from top to bottom

What is "room temperature" in terms of quantum computing? - ✔️✔️Correct-300 Kelvin

What temperature are quantum chips when they reach the bottom of the dilution fridge?

- ✔️✔️Correct-10 million Kelvin

What third quantum property is introduced when the woman speaks to the undergrad? -

✔️✔️Correct-interference

Name the 2 types of interference and briefly describe them. - ✔️✔️Correct-1. constructive

(wave amplitudes that *add* so that the signal gets larger)

2. destructive (wave amplitudes that cancel the original amplitudes)

How does interference work in quantum computing? - ✔️✔️Correct-you can control

quantum states and *amplify* the signals leading to the right answer (constructive) and

*cancel* the signals leading to the wrong answer (destructive)

What is the first step in building a quantum computer? - ✔️✔️Correct-must have a

physical device that can actually be put into the states of superposition, entanglement,

and interference (called *"qubits"* or *"quantum bits"*)

When talking to the undergrad, what name does the woman give the device that she

says can support a quantum state as well as allow scientists to manipulate that

quantum state? - ✔️✔️Correct-"superconducting qubits"

What scenario does the woman tell the undergrad is really hard for standard computers

to do that would be easier if done by a quantum computer? - ✔️✔️Correct-simulating the

system of nature

How are qubits coded as described to the grad student? - ✔️✔️Correct-with microwave

pulses of different frequencies and durations that will put the qubit(s) into a certain state

of quantum computation

What are the 2 main classes of quantum algorithms as described to the grad student? -

✔️✔️Correct-1. factoring algorithms

2. search algorithms

When the woman is speaking to the grad student she says: "The key is to come up with

algorithms where the result is __________________." - ✔️✔️Correct-deterministic

As described to the grad student, what do quantum computers require that would allow

them to process search and factoring algorithms that is not yet available? - ✔️✔️Correct-

fault tolerance

How many error corrected qubits does the woman tell the grad student that we have

today? - ✔️✔️Correct-around 50

How does the woman tell the grad student people can get involved with quantum

computing? - ✔️✔️Correct-going out and trying it and thinking about what they can do

with it

What does the professional say is ultimate task of quantum computer scientists? -

✔️✔️Correct-"build a nearly perfect computer out of a whole bunch of imperfect parts"
