Q & A

What is Moore's Law, and why is it important in computing?

Moore's Law refers to the observation that the number of transistors on a microchip doubles approximately every two years, leading to exponential growth in computing power. This principle has driven the rapid advancement of technology, enabling devices like smartphones and the internet to evolve.

Why is Moore's Law considered to be coming to an end?

Moore's Law is hitting physical limitations as transistors are approaching the size of individual atoms. At these scales, quantum and thermodynamic uncertainties create challenges in shrinking transistors further, limiting the traditional path of increasing computational power.

What is Artificial General Intelligence (AGI), and how does it relate to the current AI boom?

AGI refers to AI that can understand, learn, and perform any intellectual task at a human level or beyond. The AI boom is accelerating the pursuit of AGI, but achieving it requires immense computational power, which current technology may struggle to provide without significant innovations.

What role does light play in the future of computing?

Light is a crucial component for future computing advancements, especially through photonics. Photonic computing uses light to transfer data at incredibly high speeds with minimal energy loss, making it ideal for large-scale systems like AI supercomputers.

What is photonics, and how does it improve computing?

Photonics is the science of generating, detecting, and controlling photons (light). By integrating photonic components directly into computer chips, photonics can enable faster data transmission, reduce energy consumption, and solve issues related to bandwidth and latency in computing systems.

How does Light Matter’s technology integrate photonics into traditional computing chips?

Light Matter integrates photonic components into computer chips by using optical fibers and waveguides, allowing data to be transmitted using light. This integration enables faster communication between processors and reduces energy consumption, a breakthrough in the pursuit of AGI.

What are the challenges of using light for computing, and how has Light Matter addressed them?

The challenge lies in controlling light for computation, as light tends to scatter and doesn't easily stay in small spaces. Light Matter has developed new methods to control and manipulate light on a chip, making photonic computing viable at a scale never seen before.

What is the significance of Light Matter's Passage chip, and how does it work?

The Passage chip, developed by Light Matter, uses photonics to enable communication between processors at speeds exceeding 100 terabits per second. It integrates optical fibers and waveguides into the chip, bypassing traditional electrical interconnect limitations and enabling faster, more energy-efficient computing.

How does the size of transistors affect the performance of modern computers?

As transistors become smaller, they allow for faster and more efficient processing. However, as transistor size approaches the scale of individual atoms, the laws of physics, such as quantum and thermodynamic limitations, prevent further miniaturization, which stifles traditional performance improvements.

Why is the networking between chips considered the bottleneck in modern supercomputers?

In current supercomputers, chips are often limited by the speed and capacity of their interconnects, or networking, which links them together. As computing power increases, the inability of networking systems to keep up creates delays and inefficiencies, preventing systems from reaching their full potential.
