Microsoft shocked the tech world by announcing its Majorana 1 quantum chip on Feb. 19, marking a transformative leap of innovation in the rapidly evolving field.

Quantum computers are intended to solve highly complex calculations in areas such as machine learning, optimization, simulations, and cryptography, far beyond the capabilities of the most advanced supercomputers. Microsoft believes its novel approach has meaningfully pulled forward the roadmap for game-changing commercial applications into the coming years.

The opportunity for Microsoft to leverage its leadership in cloud computing and artificial intelligence (AI) with new enterprise-scale quantum solutions highlights a significant long-term growth potential. Here are three reasons I believe Microsoft is the new king of quantum computing.

1. The breakthrough in quantum stability and scalability

In contrast to classical computers, which rely on the sequential binary logic of 0s and 1s, a quantum architecture uses multidimensional states for processing. This power comes from qubits, the fundamental unit of information in a quantum system that utilizes the principles of superposition, entanglement, and inference to potentially process information exponentially faster.

While quantum computing technology has progressed through multiple industry advancements over the past decade, Microsoft has invented a new class of materials for quantum systems called topological superconductors.

The Majorana 1 system leverages these topoconductors to create smaller, faster, and inherently more stable qubits that dramatically reduce computational errors compared to other approaches. Perhaps the key breakthrough is its integrated virtualized digital measurement and control system, allowing for accurate qubit state readings to manage them as the systems scale toward greater power in the future.

2. The advantage of topoconductors

According to Microsoft, Majorana 1 delivers key improvements to facilitate quantum scaling with fewer trade-offs compared to current alternatives.

For example, the superconducting qubit processes used by Alphabet in its latest Willow chip or by International Business Machines in its Condor system achieve high qubit counts but are highly susceptible to environmental interference, posing practical scaling challenges. These systems rely on analog measurement techniques that require precise calibration to manage noise, a hurdle Microsoft overcomes with Majorana 1's digital approach tailored to its topoconductor qubits.

There is also IonQ, which has moved forward with its unique trapped-ion technology, with qubits controlled by lasers. This method has been shown to reduce errors, but it also operates slower, making it less suited for time-critical applications. By this measure, Majorana 1 may offer a more future-proof foundation to reach a million-qubit target. Microsoft CEO Satya Nadella emphasized this milestone. In a LinkedIn blog post, he said:

The qubits created with topoconductors are faster, more reliable, and smaller. They are 1/100th of a millimeter, meaning we now have a clear path to a million-qubit processor. Imagine a chip that can fit in the palm of your hand yet is capable of solving problems that even all the computers on Earth today combined could not!

3. A full-stack cloud ecosystem advantage

Getting past the technical jargon, what's important within the quantum computing landscape is its real-world use cases. Materials science, drug discovery, financial modeling, cybersecurity, and logistical optimizations all stand to be revolutionized. Perhaps the biggest prize on the horizon could be the role quantum computing plays in the next generation of AI to achieve concepts like artificial general intelligence (AGI), mimicking human thinking not bound by its trained data set.

Majorana 1 positions Microsoft to possibly overtake competitors by delivering a more refined quantum solution with a broader range of applications. This is particularly true among the emerging industry players, including IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing Incorporated, which will be challenged to compete with the resources Microsoft has to continue development.

Microsoft's main advantage in the long term lies in integrating Majorana 1 as a proprietary quantum hardware with the Azure cloud computing platform. That capability opens the door for Microsoft to offer a full-stack quantum-computing-as-a-service ecosystem, further enhancing its market-leading productivity tools and AI solutions with a new growth driver in the next decade and beyond.

That's a great setup for investors looking to capture exposure to the high-level themes in quantum computing through a proven tech sector leader. With its track record of success, Microsoft is well-positioned to remain at the forefront of innovation and continue to reward shareholders.
