As we continue to push the boundaries of what is computationally possible, we are not just developing a new technology, but fundamentally expanding our understanding of the universe and our place within it.

While a quantum computer could certainly cause significant economic and social disruption if used to break encryption, it does not pose the same kind of direct, physical threat to humanity as nuclear weapons. The situation is somewhat mitigated by the existence of quantum-resistant or post-quantum cryptographic schemes.

My initial motivation for studying quantum computing was a desire to understand the fundamental computational limits of the universe. Even in the absence of practical applications, I believed this pursuit was worthwhile as the most rigorous test of quantum mechanics to date. In fact, I often joke that disproving quantum computing sceptics is the primary application of a quantum computer, with everything else being a bonus.

Having recently spent two years working on AI safety and ethics at OpenAI, I have been deeply engaged in examining the moral and societal implications of artificial intelligence. With AI, we face a profound civilizational question: as AI systems become increasingly capable of performing tasks previously done by humans, what role will humans play in an AI-driven world?

A quantum computer is very similar to a classical computer, with one key difference: it takes full advantage of the laws of quantum mechanics. The heart of quantum mechanics is the concept of amplitudes. An amplitude is a new kind of number, related to but distinct from an ordinary probability. Amplitudes can be positive, negative, or even complex numbers.

The strangeness of reality was apparent long before the advent of quantum mechanics. The history of science is a sequence of revelations, each showing that the true nature of things is not what it seems to the casual observer. Quantum mechanics, however, takes this weirdness to a new level.

Quantum computing is thus not just a technological pursuit, but a deeply philosophical one, aiming to probe the very foundations of our world.

Quantum computing can be seen as a monumental effort to fully confront this exponential scaling that lies at the heart of quantum mechanics. By building and testing quantum computers, we are conducting an experiment that should either indisputably confirm this exponential nature, or overturn a century of established quantum theory.

This exponential scaling reveals the immense complexity lurking beneath the surface of reality. Taking full computational advantage of these quantum laws is the essence of quantum computing.

The surprising consequence is that amplitudes can interfere with each other. If an event can happen in two different ways, one with a positive amplitude and one with a negative amplitude, the contributions can cancel out, leading to zero probability of the event occurring. Decreasing the number of paths can paradoxically increase the likelihood of an outcome.
