Amazon recently introduced its Ocelot chip, marking its entry into this competitive arena.
To understand the meaning of these developments,it’s crucial to grasp the fundamentals of quantum computing.
Understanding Quantum Computing
Classical computing relies on bits, which represent details as 0s or 1s. In contrast, quantum computing uses qubits, the quantum equivalent of bits. Qubits, when stable and scalable, can perform complex calculations far beyond the capabilities of classical computers.
However, qubits are inherently unstable and require specific conditions, such as extremely low temperatures and minimal light, to minimize errors. Increasing the number of qubits further exacerbates the error rate,making progress challenging.
while small-scale quantum computers exist, the primary focus is now on scaling them up for broader use.
Each company is tackling the error reduction and scalability problems with unique strategies.
Microsoft’s Topological Qubits
microsoft’s Quantum Approach
Approach to quantum: Topological qubits
Moast powerful machine: Majorana 1
Microsoft introduced its Majorana 1 chip in February, aiming to accelerate the development of large-scale quantum computers. Microsoft believes this could reduce the timeline from decades to years.
Microsoft states that the Majorana 1 chip utilizes a novel state of matter to create “topological” qubits, which are designed to be more stable and less susceptible to errors. This topological state of matter differs from conventional states like liquid, gas, or solid. these quantum particles can “retain a ‘memory’ of their position over time and move around each other.” This allows information to be stored across the entire qubit, making it more fault-resistant.
According to Tom darras, founder of quantum computing startup Welinq, “Microsoft’s progress is the hardest to get an idea about as it’s very niche. Even experts in the industry find it arduous to assess the quality of these results.”
Despite the challenges, some experts view Microsoft’s approach as promising, even though “Microsoft still has many roadblocks to overcome.”

Google’s Quantum Leap with Willow
Google has unveiled its latest quantum chip, Willow, marking a significant advancement in quantum computing. The company claims that Willow can solve a problem in just five minutes that would take the world’s fastest supercomputer 10 septillion years.
A key breakthrough with Willow is its scalability. Researchers at Google have found that adding more physical qubits to the quantum processor actually reduces error rates, a reversal of the typical trend. This “below threshold” achievement addresses a challenge that has persisted since the 1990s.
In a study published in Nature, Google’s researchers suggest this could pave the way for building a useful, large-scale quantum computer. However, this remains largely theoretical, and Google now faces the task of proving its practicality.
Amazon’s Cloud-Based Quantum computing with Ocelot
Approach to quantum: Superconducting qubits
Most powerful machine: ocelot
Amazon Web Services (AWS) announced its Ocelot chip in late February, a prototype aimed at advancing its cloud-based quantum computing efforts.
an Amazon spokesperson stated that the Ocelot prototype has the potential to increase efficiency in quantum error correction by up to 90% compared to conventional methods. The chip uses a unique architecture that integrates cat qubit technology,named after the famous Schrödinger’s cat thought experiment,along with quantum error correction components manufactured using electronics industry processes.
Troy Nelson, a computer scientist and CTO at Lastwall, a cybersecurity provider of quantum resilient technology, noted that Amazon’s Ocelot chip is a crucial building block for a functioning quantum computer. However, he emphasized that its error rate needs to be substantially reduced, and the chips require greater qubit density to be truly useful.
“There’s lots of challenges ahead. What amazon gained in error correction was a trade-off for the complexity and the sophistication of the control systems and the readouts from the chip,”
Troy Nelson, CTO at Lastwall
Nelson added, We’re still in prototype days, and we still have multiple years to go, but they’ve made a great leap forward.
IBM’s Quantum Frontrunner: Condor and Heron
Approach to quantum: Superconducting qubits
Most powerful machine: Condor
IBM has been a quantum frontrunner for some time, with several prototype chips and the development of Q System One, the first circuit-based commercial quantum computer, unveiled in January 2019.
IBM’s Condor chip is the company’s most powerful in terms of qubit count. However, IBM has since focused on improving the quality of gate operations and making its newer quantum chips modular, allowing multiple smaller, less error-prone chips to be combined for greater computing power.
The Condor, the second-largest quantum processor ever made, was unveiled at the IBM Quantum Summit 2023 on December 4, 2023.Simultaneously, IBM introduced its Heron chip, a 133-qubit processor with a lower error rate.
Rob Schoelkopf, cofounder and chief scientist of Quantum Circuits, observed that IBM has prioritized “error mitigation” over conventional error correction approaches. While IBM has seen success with “brute force scaling,” Schoelkopf believes this methodology will need adjustments for long-term efficiency.
The Quantum Race: Who’s Ahead?
Sankar Das Sarma, a theoretical condensed matter physicist at the university of Maryland, noted that the Amazon Web Services Ocelot chip, Google’s Willow, and IBM’s condor use a “more conventional” superconducting approach to quantum development compared to some competitors.
In contrast, Microsoft’s approach centers on topological Majorana zero modes, which also involve a superconductor but in “a radically different manner.” Das Sarma suggests that if the Majorana 1 chip works correctly, it would be topologically protected, minimizing the need for error correction compared to claims of improved conventional error correction methods from other tech companies.
Das Sarma emphasized that each company’s approach is “very different,” adding, It is premature to comment on who is ahead since the whole subject is basically in the initial development phase.
Georges-Olivier Reymond, CEO of quantum computing startup Pasqal, cautioned Big Tech companies against “raising expectations when promoting results,” warning that Otherwise, you could create disillusionment.
Scott Crowder, IBM’s VP of quantum adoption and business development, echoed this sentiment, expressing concern that “over-hype” could lead people to dismiss quantum technology before its potential is realized.
“We think we are on the cusp of demonstrating quantum advantage,”

Classical computing relies on bits, which represent details as 0s or 1s. In contrast, quantum computing uses qubits, the quantum equivalent of bits. Qubits, when stable and scalable, can perform complex calculations far beyond the capabilities of classical computers, leveraging phenomena like superposition and entanglement.
- Superposition allows a qubit to exist in a combination of 0 and 1 simultaneously, unlike a classical bit that can only be 0 or 1. This dramatically increases the possible states the computer can explore.
- Entanglement links the states of two or more qubits together, even when separated by large distances. Measuring the state of one entangled qubit instantly determines the state of the others, enabling complex computations.
However, qubits are inherently unstable and require specific conditions, such as extremely low temperatures (near absolute zero for superconducting qubits) and shielding from electromagnetic interference, to minimize errors. This susceptibility to environmental “noise” is known as decoherence. Increasing the number of qubits further exacerbates the error rate, making progress challenging.
While small-scale quantum computers exist, the primary focus is now on scaling them up for broader use, while simultaneously tackling the challenge of error correction. Fault-tolerant quantum computing is the ultimate goal,where computations can proceed reliably even with some degree of qubit error.
Each company is tackling the error reduction and scalability problems with unique strategies,focusing on different types of qubits and error correction methods.

Approach to quantum: Topological qubits
Most powerful machine: Majorana 1
microsoft introduced its Majorana 1 chip in February,aiming to accelerate the development of large-scale quantum computers. Microsoft believes this could reduce the timeline from decades to years.
Microsoft states that the Majorana 1 chip utilizes a novel state of matter to create “topological” qubits, which are designed to be more stable and less prone to errors than traditional qubits. The key concept is that information is stored and processed based on knots and braids in the quantum state, making it intrinsically resilient to local perturbations. These qubits are based on Majorana zero modes, exotic quasiparticles that are their own antiparticles. Topological qubits aim to achieve intrinsic error correction due to quantum information being protected by the laws of topology.
The advantage of topological qubits is that they should be inherently more stable, reducing the need for complex error correction schemes. The downside is that creating and controlling these qubits is extremely challenging from a materials science and engineering standpoint.
Quantum Computing Methods
Beyond topological qubits, several approaches are being pursued. Here’s an overview:
- Superconducting Qubits: This approach involves creating qubits from superconducting circuits cooled to extremely low temperatures. Companies like Google, IBM, and Amazon are using this method. These qubits are relatively easier to fabricate but are highly sensitive to noise. Examples: Google’s Willow, IBM’s Condor/Heron, Amazon’s Ocelot
- Trapped Ions: This method uses individual ions (electrically charged atoms) held in place by electromagnetic fields. Qubits are encoded in the internal energy levels of the ions. Trapped ions offer high fidelity and long coherence times but are typically slower than Superconducting Qubits.Companies like IonQ and Quantinuum are working with Trapped ions.
- Photonic Qubits: Photons (particles of light) are used to encode and process quantum information. Photonic qubits are less susceptible to decoherence,and can operate at room temperature. Xanadu is a leading company working with photonic qubits.
- Neutral Atoms Uses neutral atoms trapped by lasers to form qubits. like trapped ions, they have long coherence times, but the setups can be quite complex. ColdQuanta
