The race to develop the first quantum computer is fiercely competitive among various tech giants.
In the ever-advancing landscape of technology, quantum computing has emerged as the next frontier in the pursuit of unimaginable computational power. So, what exactly is quantum computing? Well, it’s a super-powered computer designed to tackle problems that would take regular computers ages to solve, thanks to its impressive computing power.
Quantum computers gain significant computational power as more qubits are connected, while classical computers rely on increased transistors for their power. Transistors are electronic components in traditional computers that control the flow of electrical signals. On the other hand, qubits are the fundamental information units in quantum computers, leveraging the principles of quantum mechanics to encode and manipulate data.
As traditional computers approach their limits in solving complex problems, tech giants have embarked on a thrilling race to harness the potential of quantum supercomputers. Companies like IBM, Google, Microsoft and others are investing heavily in research and development, aiming to transform the theoretical possibilities of quantum computing into tangible applications with the potential to revolutionize industries across the board.
Quantum vs. Traditional Computers: A race to redefine computing
Quantum and traditional computers are fundamentally different in how they operate, representing distinct computing paradigms. Quantum computers necessitate more precise control over physical conditions due to the principles of quantum mechanics. In contrast, classical computers have lower computational power and limited scalability than quantum computers. Another distinction lies in the basic units of data used: classical computers employ bits, whereas quantum computers utilize qubits.
In 2019, Google announced that they conducted a calculation on a quantum computer that would take a classical computer 10,000 years to complete, but it only took them a few minutes. A little over a year later, a Chinese team surpassed this achievement by performing a calculation in 200 seconds that would take an ordinary computer 2.5 billion years to accomplish—making it 100 trillion times faster.
These groundbreaking advancements in quantum computing demonstrate the immense potential for quantum systems to outpace classical computers in solving complex problems. The exponential speed demonstrated by quantum computers has the potential to revolutionize various fields by tackling complex problems quickly. The ongoing progress in this area fuels excitement and intensifies the global race to unlock the full potential of quantum technology.
Top players in the race
As the stakes are high and the potential rewards immense, tech giants are pushing the boundaries to establish dominance in the emerging era of quantum computing. Let’s take a look at some leading players in this race.
IBM
In November 2022, tech major IBM achieved a significant milestone by unveiling the largest quantum computing system, equipped with 433 qubits. Now the company has shifted its focus towards an even more ambitious goal—a quantum machine with a staggering 100,000 qubits, which it aims to develop within the next decade in collaboration with the University of Tokyo and the University of Chicago.
This transformative US$100 million initiative seeks to push the potential of quantum computing to tackle immense challenges. These include gaining deeper insights into chemical reactions, understanding the dynamics of complex molecular processes, addressing urgent climate change issues and addressing other significant and complex problems that have eluded traditional computing approaches.
In addition to the two universities, IBM has plans to broaden its partnerships by involving Argonne National Laboratory and Fermilab National Accelerator Laboratory. Notably, both laboratories possess valuable expertise and capabilities that will play a crucial role in advancing the development of the envisioned quantum-centric supercomputer.
Microsoft
In June 2023, Microsoft unveiled its intention to develop a specialized quantum supercomputer within a decade. The company asserted that quantum supercomputers have the potential to bring about revolutionary advancements in fields such as chemistry, climate change mitigation and addressing food scarcity.
Microsoft has outlined three milestones for the development of programmable quantum supercomputers. Currently, in the foundational stage, test machines with “noisy” physical qubits lack the advantage of solving real problems. To advance, the company has integrated multiple machines into Azure Quantum Elements, a service that accelerates scientific discovery. The next milestone involves improving qubit reliability and bundling them into logical qubits. Finally, the ultimate objective is to develop a quantum supercomputer that surpasses classical supercomputers in problem-solving capabilities at a large scale.
To fully harness the power of quantum computing, it is crucial to reduce the error rate of quantum operations. Currently, quantum computers have relatively high error rates due to the sensitivity of qubits to environmental noise and other factors.
In July 2023, Google announced a major advancement in quantum computing, claiming to have achieved “quantum supremacy.” The company claims that its upgraded version of Sycamore quantum computer can solve highly complex calculations in mere seconds, a task that would take the fastest supercomputers from their competitors approximately 47 years to complete.
The upgraded Sycamore quantum computer boasts 70 qubits, significantly increasing from its predecessor’s 53 qubits. This upgrade in qubits translates to a machine that is 241 million times more potent and faster than the 2019 Sycamore model.
In 2019, Google stated that it had achieved quantum supremacy with its Sycamore quantum processor. According to the company, Sycamore performed a specific calculation in 200 seconds that would take the world’s most powerful supercomputer 10,000 years to complete. This was a significant milestone in quantum computing, demonstrating that quantum computers can solve specific problems much faster than classical computers.
However, this claim was challenged by some of Google’s competitors, which contended that Google had exaggerated the disparity between its machine and traditional supercomputers. The discourse surrounding Google’s assertion of achieving quantum supremacy has shed light on the existing challenges within the field of quantum computing.
The future of quantum computing
Although these milestones signify significant progress, a substantial amount of research and development is still required to enhance the reliability and performance of quantum computers. Additionally, it is crucial to showcase their practical applications in addressing real-world problems to validate their potential further.
Despite the challenges, several other companies are progressing toward developing more robust and reliable quantum computers. However, it remains to be seen which company will ultimately come out ahead and make the first commercially viable quantum computer. The race is on, and the outcome will have significant implications for the future of computing and technology.
