The advent of “commercially useful” quantum computers is on the horizon, with top executives predicting their arrival within the next five to seven years. This transformative technology is expected to follow a trajectory similar to the exponential growth seen in semiconductor capabilities, potentially ushering in a new era of computational power.
Peter DeSantis, who recently took the helm of a new Amazon division dedicated to AI, chips, and quantum computing, shared these insights, drawing a parallel to Moore’s Law. This principle, which observes the doubling of transistors on a microchip roughly every two years, has driven unprecedented advancements in classical computing. DeSantis believes a similar, albeit distinct, growth pattern will emerge for quantum systems.
“I actually do believe, over the next five-to-seven years, we’re going to start to see the first commercially useful small-scale quantum computers,” DeSantis told CNBC. “From there, we’re going to see something that looks a lot like Moore’s Law, where they’re going to get bigger and bigger every year, and they’re going to be able to tackle more and more interesting problems.”
This marks Amazon’s first concrete timeline projection for practical quantum computing applications. The potential of quantum computing lies in its ability to address complex problems that remain intractable for even the most powerful classical computers. Unlike classical bits, which represent either a zero or a one, quantum bits, or qubits, can exist in a superposition of states, allowing for exponentially more complex computations.
“One of the misnomers is a quantum computer is going to be a faster computer; that’s not it at all,” DeSantis clarified. “A quantum computer is going to solve a very particular type of problem that isn’t solved well today with a classic computer, and it’s going to solve it much better.”
The field is experiencing intense competition, with major technology players like Microsoft, Google, and IBM heavily invested in quantum research and development, alongside a burgeoning ecosystem of startups. Amazon has also made significant strides, unveiling its Ocelot quantum computing chip last year, specifically designed to tackle error correction, a critical hurdle in quantum technology.
DeSantis’ forecast positions Amazon’s timeline as a moderate outlook within the broader industry predictions. Google, for instance, has previously suggested that practical quantum applications could emerge within five years, while Microsoft has set a target of 2029 for a commercially viable quantum machine. Earlier, Nvidia CEO Jensen Huang had offered a more distant projection, suggesting 15 to 30 years, although he later qualified those remarks.
The initial wave of quantum applications is anticipated to focus on “quantum-based problems,” according to DeSantis. These include areas like chemistry and material science, where simulating molecular interactions with high fidelity is currently beyond the reach of classical computing. The advent of effective quantum computers promises to unlock significant breakthroughs in these fundamental scientific disciplines.
The development of quantum computing represents a paradigm shift in computational capabilities, with the potential to revolutionize diverse sectors from drug discovery and financial modeling to advanced materials design and artificial intelligence. As the technology matures and its accessibility increases, the implications for scientific research and industrial innovation are profound.
