Quote of the day by Alphabet CEO Sundar Pichai: "Quantum is where AI was five years ago" — insight on the next big tech craze

The quantum computing race has started to heat up in recent years as big tech companies and university research teams (often in collaboration) have embarked on refining the weird and wonderful technology of quantum computing. Google, like IBM, Amazon, and other entities, is at the heart of this.

“The progress is so exciting. I would say quantum is there where maybe AI was five years ago. So I think in five years from now we’ll be going through a very exciting phase in quantum, and we are investing with a view towards that.”

The impact of technology

Five years ago, AI was still a term we used to describe simple machine learning functions and neural network-based research projects. Now, it's used to describe a wave of technologies that are reshaping society.

Sundar Pichai, whose own company oversees a sophisticated and promising quantum computing roadmap, spoke of the overall quantum journey the industry is undertaking in an interview with the BBC late last year.

Roadmapping quantum computing's ascendency

The holy grail in the roadmap that many legacy tech companies and newfangled startups born out of college labs are chasing is a fully fault-tolerant quantum computer that can outpace the fastest supercomputers in useful, real-world calculations.

It's not enough for the machine to simply be packed with as many qubits as possible, because they're far more error-prone than regular computing bits. Without proper error correction measures (which scientists are busy investigating), calculations cannot sustain momentum and fall apart before they can be useful.

In December 2024, Google became the first company to achieve "below threshold" error correction, meaning (in theory) the more qubits you add to a system, the more errors are removed – not added as they are now. With so many industry players making comparable breakthroughs today, it doesn't mean Google will be the first to give quantum computing its 'ChatGPT' moment within, say, five years.
