Google's Quantum AI Head Predicts Breakthrough in Five Years
Google's quantum AI Hardware department head, Julian Kelly, has stated that the practical application of quantum computing could be just five years away. During an interview, Kelly expressed his belief that quantum computers could achieve unprecedented technological breakthroughs, including conducting advanced research in physics and generating new types of data. He noted, "We believe that in about five years, quantum computers will experience a genuine breakthrough, enabling them to solve real-world problems that only quantum computers can address."
Kelly further elaborated that the initial applications of quantum computing are likely to focus on simulating advanced physics, an area of research that often exceeds the processing capabilities of traditional computers. Quantum computers, with their ability to handle multiple states simultaneously through "qubits," offer a significant advantage over traditional binary systems. This unique capability allows quantum computers to tackle complex problems far more efficiently than their classical counterparts.
The potential of quantum computing has garnered significant attention, particularly after Google's recent breakthrough in quantum error correction. In December, google announced progress in this area, which experts believe paves the way for the development of practical quantum computers. Currently, Google's most advanced quantum computer boasts 105 qubits, although experts suggest that achieving widespread, useful applications may require quantum computers with millions of qubits.
Other tech giants are also making strides in the quantum computing race. Microsoft, for instance, introduced a new quantum computing chip called "Majorana" in February. This chip operates on a novel material state, bringing quantum computing closer to practical use. Microsoft's CEO, Satya Nadella, highlighted that creating this new material state is aimed at enhancing the efficiency of quantum computers in processing information.
Meanwhile, NVIDIA, although not a producer of quantum processors, hosted a "Quantum Day" event last week. The event brought together representatives from leading quantum companies, as well as major corporations, to discuss the future potential of quantum technology. Despite the promising outlook, quantum computing still faces numerous challenges. NVIDIA's CEO, Jensen Huang, previously stated that it could take 15 years or more for quantum computers to enter the market and achieve practical applications. However, Huang later clarified his remarks, acknowledging that his earlier timeline was incorrect, though he maintained that the technology still has a long way to go. He emphasized, "Quantum computing certainly has potential, and everyone hopes it will bring extraordinary impacts, but the complexity of this technology is beyond imagination."
