The quantum race is heated.
Tech Titans Amazon, Google, IBM and Microsoft have recently announced progress in their prototype chips, tightening the race to develop a commercially useful quantum computer which could solve some of the most sticky problems in the universe faster than a conventional computer has never been able.
Quantum IT is a rapidly evolving area – although still largely theoretical and deeply technical. But Opening the opening could help discover new drugs, develop new chemical compounds, or Break of encryption methodsAmong other results, the researchers say.
Naturally, each of the main players in Big Tech wants to be the only one to take quantum computer current.
“You hear a lot about this because it is a real tilting point,” Business Insider Oskar Painter, Amazon Web Equipment Director, told Business Insider, after the announcement by the company of its Oclot chip.
Stay with us – this is where it gets complicated.
When conventional IT uses binary figures – 0s and 1, called Bits – To represent information, quantum IT is based on a foundation built from the quantum bits equivalent, called qubits. When they behave predictably on a sufficiently large scale, qubits allow quantum computers to quickly calculate equations with several solutions and to carry out advanced calculations which would be impossible for conventional computers.
However, the qubits are unstable and their behavior is unpredictable. They require specific conditions, such as small light and extremely cold environments, to reduce errors. When the number of qubits increases, the error rate increases – which makes progress in the slow field.
Quantum computers on a small scale already exist, but the race is underway to make them evolve and make them useful to a wider audience rather than scientists.
Recently, Amazon, Google and Microsoft have announced new prototype chips, and IBM has made progress in its existing quantum roadmap. Each company uses unique approaches to solve the problems of error and scalability that have long tormented the field and make useful IT a reality.
Here’s how each approach accumulates.

Approach to quantum: Topological qubits
Most powerful machine: Majorana 1
In February, Microsoft unveiled its new quantum chip, Majorana 1.
Microsoft said that the chip uses a new matter of material to produce “topological” qubits which are less prone to errors and more stable. Essentially, it is a qubit based on a topological state of matter, which is not a liquid, gas or solid. Consequently, these quantum particles could maintain a “memory” of their position over time and move with each other. Consequently, the information could be stored on the entire qubit, so if parts fail, the topological qubit could always contain key information and become more resistant to breakdowns.
“Microsoft’s progress is the most difficult to get an idea because it is very niche,” said Tom Darras, founder of the quantum calculation startup Welinq. “Even industry experts find it difficult to assess the quality of these results.”
Quantum experts agree that Microsoft still has many road dams to overcome, and its nature document evaluated by peers only shows aspects of what its researchers have claimed to achieve – but some in the quantum ecosystem see it as a promising result.

Most powerful machine: Willow
In December, Google announced Willow, its new quantum chip, which, according to the company, takes only five minutes to solve a problem that would take the fastest supercomputer in the world 10 septillion.
Perhaps more impressive was Google’s breakthrough in the way quantum computers are evolving. Historically, the more qubits that are added and the more powerful the computer becomes, the more it is subject to errors. With Willow, Google’s researchers said that adding physical qubits to a quantum processor made it less subject to errors, reversing the typical phenomenon.
Known under the name of “lower threshold”, the accomplishment marks an important step by holding an problem that has existed since the 1990s. In a study published in Nature, Google researchers pose that this breakthrough could finally offer a means of building a useful large -scale quantum computer. However, a large part of this is always theoretical, and now Google will have to prove it in practice.

Most powerful machine: Ocelot
At the end of February, Amazon Web Services announced its Ocelot chip, a prototype designed to advance the company on quantum computer based on the cloud.
A Amazon The spokesperson told Business Insider that the Ocelot prototype had demonstrated the potential to increase the efficiency of the correction of quantum errors up to 90% compared to conventional approaches. The chip exploits a unique architecture that incorporates CAT QUBIT technology – named for the famous Schrödinger cat Thought of thought – and additional quantum error correction components which can be manufactured using processes borrowed from the electronics industry.
Troy Nelson, a computer scientist and technology director at Lastwall, a quantum resilient technology cybersecurity supplier, told Business Insider that the Amazon Ocelot chip is another constitutive element that the industry will use to build a functional quantum computer. However, its error rate must be considerably reduced and its chips would require more qubit density before being useful.
“There are a lot of challenges to come. What Amazon has gained in the correction of errors is a compromise for the complexity and sophistication of control systems and the readings of the chip,” said Nelson. “We are still in prototype, and we still have several years to do, but they have brought a big leap forward.”

Approach to quantum: Superconductive qubits
Most powerful machine: Condor
IBM has been a quantum favorite for some time, with several different prototype chips and its development of Q System One, the first quantum commercial computer based on circuits, unveiled in January 2019.
The IBM Condor chip is the most powerful of the company in terms of number of qubits. However, since its development, IBM has concentrated its approach on the quality of its grid operations and the creation of more recent quantum chips, therefore several smaller and less prone to errors can be combined to make more powerful quantum calculation machines.
Condor, the second largest quantum processor never produced, was unveiled at IBM Quantum Summit 2023 on December 4, 2023. At the same time, IBM made its debut on its heron chip, a processor of 133 qubit with a lower error rate.
Rob Schoelkopf, chief co -founder and scientist of quantum circuits, told Business Insider that IBM had prioritized “error attenuations” compared to traditional error correction approaches. Although IBM has so far been successful what Schoelkopf calls “the scaling of brute force” with this approach, he has declared that the methodology will have to be modified in the long term for efficiency.
Sankar Das Sarma, theoretical physicist condensed at the University of Maryland, told Business Insider that the Amazon Web Service Oclot Chip, Google’s Willow and IBM’s Condor use a more conventional “superconductive” approach to quantum development compared to other competitors.
On the other hand, Microsoft’s approach is based on topological modes Majorana Zero, which also have a superconductor, but in a radically different way, “he said. If the Majorana 1 chip works correctly, added Sarma, it is protected topologically with a minimum need for error correction, compared to complaints from other technological companies that they have improved methods of error error methods conventional.
However, the approach of each company is “very different,” said Das Sarma. “It is premature to comment who is ahead because the whole subject is essentially in the initial development phase.”
Large technological companies should be cautious about the “increase in expectations when promoting results,” said Georges-Olivier Reymond, CEO of Quantum Computing Startup Pasqal. “Otherwise, you could create a disillusionment.”
Reymond’s feeling was taken over by IBM’s quantum and commercial development vice-president, Scott Crowder, who told Business Insider that he was concerned about “over-hype” could lead people to update quantum technology before his promise could be carried out.
“We believe that we are about to demonstrate the quantum advantage,” said Crowder, referring to the time a quantum computer surpassing conventional machines. “But the industry is still a few years old from a quantum computer entirely tolerant of the breakdowns.”
