91. Quantum Computing: A New Kind of Computer

According to the essay, what is the fundamental component that makes quantum computers different from normal computers?
1. Advanced cooling systems
2. Artificial intelligence
3. Qubits
4. Faster processing chips
What special property do qubits have, according to the rules of quantum physics?
1. They are completely error-free.
2. They can be both 0 and 1 at the same time.
3. They are much larger than regular bits.
4. They only work at very high temperatures.
The essay suggests quantum computers could be useful for all of the following EXCEPT:
1. Discovering new medicines
2. Replacing all home computers for everyday use
3. Improving financial planning
4. Making transportation more efficient
Why is building a quantum computer so difficult?
1. They require too much electricity to operate.
2. Qubits are very sensitive and can easily lose information.
3. The materials needed are not available on Earth.
4. They are too large to fit in a standard laboratory.
What is the current state of quantum computing, as described in the essay?
1. It is already a common technology in most homes.
2. It is a mature technology that has solved all major challenges.
3. It is still in early stages, with companies and governments actively researching it.
4. It has been abandoned due to its many difficulties.
