Q & A

What is the current state of quantum computing according to the speaker?

The speaker states that quantum computing is still in a very early stage, with only a handful of algorithms designed and tested on a limited basis. It is not yet defined and is still largely in the realm of science fiction for practical use.

What does the speaker believe about the possibility of seeing quantum computing in their lifetime?

The speaker does not believe they will live to see quantum computing become a reality for the general public, as it is still extremely far off and requires overcoming significant technical challenges.

What is the significance of the leap from CPUs to GPUs in AI and how does it relate to potential quantum computing advancements?

The leap from CPUs to GPUs was significant because it allowed for the handling of complex matrix calculations required for deep learning, which was previously not feasible. A similar leap to quantum computing could drastically increase processing speed by simplifying these calculations.

What are the technical challenges that need to be overcome for quantum computing to become practical?

Quantum computing requires extremely stable conditions, such as being close to absolute zero to prevent any excitation that could flip the quantum bit. There is also the challenge of finding the best materials and methods to stabilize quantum states.

What is the speaker's view on the potential impact of quantum computing on AI and machine learning?

The speaker suggests that if quantum computing were to become practical, it could significantly enhance AI and machine learning by allowing complex calculations to be performed much more quickly and efficiently.

What does the speaker mention about the use of GPUs in the early days of AI and deep learning?

The speaker mentions that GPUs were initially used for graphics but were later adopted for AI and deep learning because of their ability to handle matrix calculations more efficiently than CPUs.

What historical example does the speaker provide to illustrate the potential for unexpected technological advancements?

The speaker talks about the use of PlayStation 2 consoles in parallel to create a makeshift GPU setup for running projects that required significant computational power when GPUs were not yet available.

Why does the speaker compare the potential of quantum computing to a 'quantum leap' in technology?

The comparison is made because quantum computing could theoretically allow for the simultaneous processing of multiple states, leading to an exponential increase in computational power, much like the leap from CPUs to GPUs.

What are some of the practical limitations that quantum computing faces according to the speaker?

Practical limitations include the need for extremely low temperatures to maintain quantum states, the sensitivity of quantum bits to any form of interference, and the current lack of knowledge about the best materials and methods for stabilization.

What is the speaker's opinion on the future of computer architecture and its potential limitations?

The speaker believes that current computer architecture has reached a plateau that is difficult to surpass, with physical limitations such as the size of transistors approaching the atomic level, where quantum effects start to interfere with their function.

What is the significance of Alan Turing's work mentioned by the speaker?

Alan Turing's work is significant because it laid the foundational concepts for what is computable and what is not, establishing the limits of what computers can achieve and introducing the idea of non-computable numbers.
