Practice Listening: Multiple Choice, Single Answer ID: #43880 Medium QuantumBits
Instructions ›
You will see a video about the development of quantum bits and their manufacturing. Listen to the recording and answer the multiple-choice question by selecting the correct response. Only one response is correct.

Transcript:

And over the last 20 years or so, since the idea came about that we could actually start manufacturing quantum bits, there's been a lot of progress on the academic side. It's actually, I think, a really funny way how this kind of started was that already sort of in the early 1900s? We knew that we could calculate using the idea of quantum bits, or at least according to the rules of quantum mechanics. Yeah.
Uh, we just had no physical way in which we had precise enough control over those units of quanta that we could actually do anything with this. And not just that, but also just not even the tools to make it artificially so the same. So the chips you see here, especially the. Top left, top right, bottom, right. Those are manufactured specifically using current nano fabrication techniques that have only existed. Now for let's say the last 20 years or so.

What was the main challenge in using quantum bits in the early 1900s?

Option 2: "Inability to control units of quanta precisely."

Explanation: The text explicitly states that there was no physical way to have precise control over the units of quanta, which is identified as the main challenge in using quantum bits during that time. This option is correct as it directly reflects the main idea presented in the text.

Option 1: "Lack of theoretical understanding of quantum mechanics."

Explanation: The text indicates that there was an understanding of quantum mechanics in the early 1900s, as it mentions that we knew we could calculate using the idea of quantum bits. Therefore, this option is incorrect because it contradicts the information provided in the text.

Option 3: "Absence of computational problems to solve."

Explanation: The text does not mention anything about the absence of computational problems. Instead, it focuses on the inability to control quanta. Thus, this option is incorrect as it introduces information that is not supported by the text.

Option 4: "Limited interest in quantum computing research."

Explanation: The text does not discuss interest levels in quantum computing research. It focuses on the technical challenges faced in the early 1900s. Therefore, this option is incorrect as it does not align with the content of the text.
