- Amazon, Google, IBM and Microsoft giants are competing to develop a quantum functional computer.
- Each has issued a quantum prototype chip with different access and possible applications.
- The field is rapidly evolving, but the main obstacles remain before it becomes useful trade.
Quantum racing is getting hot.
Tech Titans Amazon, Google, IBM and Microsoft each recently announced progress in their prototype chips, tightening the race to develop a useful commercial quantum computer that can solve some of the most adhesive problems of the universe than a classic computer sometimes.
Quantum calculation is a rapidly evolving field – though still largely theoretical and deeply technical -. But Cracking it Open can help detect new medicines, develop new chemical compounds, or The methods of encryption of decayAmong other results, the researchers say.
Of course, each of the leading players in the Big Tech wants to be the one who will get the quantum calculation flow.
“You are listening a lot about it because this is a real takeover point,” Oscar Painter, the director of Quantum Hardware at Amazon Web Services, told the Business Insider in late February, after notifying his chip Ocelot.
Stay with us – here it becomes complicated.
When classic calculation uses binary figures – 0 and 1, called bit – to represent the information, the quantum calculation is based on a foundation from the quantum equivalent of bits, called Qubits. When they behave predictably to a sufficient degree, Qubits allow quantum computers to quickly calculate equations with numerous solutions and perform advanced calculations that would be impossible for classical computers.
However, Qubits are unstable, and their behavior is unpredictable. They require specific conditions, such as low light and extremely cold environments, to reduce errors. When the number of QUBITs increases, the error rate increases – making advancing in the slowdown of the field.
Small -scale quantum computers already exist, but the race is scalancing them and making them useful for a wider audience than just scientists.
Recently, Amazon, Google and Microsoft have announced new prototype chips, and IBM has made steps on its existing quantum road map. Companydo company is using unique access to solve error reduction and scaling problems that have plagued the field and make it a useful quantum calculation reality.
Here’s how each approach accumulates.

In February, Microsoft discovered its new quantum chip, Majorana 1. The goal is for the chip to speed up the development of large -scale quantum computers from decades to years.
Microsoft said the chip uses a new state of matter to produce “topological” Qubits that are less prone to errors and more stable. Basically, this is a cube based on a topological state of matter, which is not a liquid, gas or rigid. As a result, these quantum particles can hold a “memory” of their position over time and move around each other. Therefore, the information can be stored across the Qub, so if any part fails, topological Qubit can still hold a major part of the information and become more guilt resistant.
“Microsoft’s progress is the most difficult to get an idea because it is very warm,” said Tom Darras, the founder of the beginning of Quantum Computing Welinq. “Even experts in the industry find it difficult to evaluate the quality of these results.”
Quantum experts agree that Microsoft still has many road barriers to overcome, and his work revised by peers demonstrates only aspects of what its scholars have claimed to achieve-but some in the quantum ecosystem see it as a promising result.

In December, Google announced Willow, its newest quantum chip, for which the company claims only requires five minutes to solve a problem that would get the fastest September 10th Super -Computer.
Perhaps the most impressive was Google’s progress on how the scale of quantum computers. Historically, the more cubes that are added, and the more powerful the computer becomes, the more prone the mistakes. With Willow, Google researchers said the addition of more physical cubes to a quantum processor actually made it less prone to mistakes, changing the typical phenomenon.
Known as the “under the threshold”, the achievement marks an important milestone by hitting a problem that has been around since the 1990s. In a study published in Nature, Google researchers present this progress can finally provide a way to build a useful large -scale quantum computer. However, many of this are still theoretical, and now Google will have to try it in practice.

Most Powerful Cars: Ocelot
At the end of February, Amazon Web Services announced its Ocelot Chip, a prototype created to advance the company’s concentration in the Quantum calculation based on the Cloud.
A Amazon The spokesman told Business Insider Prototype Ocelot demonstrated the potential to increase efficiency in the correction of quantum error by up to 90% compared to conventional approaches. Chip uses a unique architecture that integrates Qub’s cat technology – called for celebrities Schrödinger’s cat Experiment of thought – and additional quantum error correction components that can be produced using processes borrowed from the electronic industry.
Troy Nelson, a computer scientist and leading technology official in Lastwall, an online elastic internet security provider, told Business Insider that Amazon’s Ocelot chip is another block that the industry will use to build a quantum operating computer. However, his error rate must be significantly reduced, and his chips will require more Qub density before they are useful.
“There are many challenges ahead. What Amazon gained in the error correction was a trading on the complexity and sophistication of control systems and readings from Chip,” Nelson said. “We are still on prototype days, and we still have many years to go, but they have made a great step forward.”

IBM has been a quantum precursor for some time, with several different prototype chips and its development Qystem One, the first circuit -based quantum trade computer discovered in January 2019.
IBM’s chip Condor is the company’s most powerful in its number of QUBITs. However, since its development, IBM has focused its approach on the quality of its gate operations and making its quantum quantum modules, so numerous smaller, less prone chips can be combined to make more powerful quantum computing machines.
Condor, the second largest quantum processor ever made, was discovered at the IBM 2023 summit on 4 December 2023. At the same time, IBM debuted its hero, a 133-kuba processor with a lower error rate.
Rob Schoelkopf, a leading collaborator and scientist of quantum circles, told Business Insider that IBM has prioritized the “error softening” on traditional error correction approaches. While IBM has so far been successful in what Schoelkopf calls “scaling of brutal force” with this approach, he said the methodology will have to be modified in the long -term plane for efficiency.
Who runs the race?
Sankar Das Sarma, a theoretical physicist of condensed matter at the University of Maryland, told Business Insider that the Amazon, Willow’s Willow and Condor Condor Chip Ocelot use a “more conventional” approach overlapping quantities compared to other competent competents.
In contrast, Microsoft’s approach is based on the topological ways Majorana zero, which also have a supervisor, but in “a radically different way,” he said. If Chip Majorana 1 works correctly, Das Sarma added, it is topologically protected by minimal need for error correction, compared to the claims of other technology companies that have improved the methods of correction of conventional error.
However, each company’s approach is “very different,” Das Sarma said. “It is premature to comment on who is ahead as the whole subject is essentially in the initial stage of development.”
Large technology companies need to be careful about “raising expectations when promoting results,” said Georges-Olivier Reymond, CEO of Quantum Computation Pask. “Otherwise, you can create disappointment.”
Reymond’s feeling was echoed by IBM’s VP for quantum adoption and business development, Scott Crowder, who told Business Insider that he is worried “over-problems” could lead people to deduct quantum technology before his promise is realized.
“We think we are on the verge of demonstrating the quantum advantage,” Crowder said, referring to when a quantum computer exceeds classic cars. “But the industry is still a few years from a fully tolerant quantum computer.”
