Quantum Computing Stocks Explained: What It Is & Its Impact on Financial Markets
Quantum computing is arguably one of the most cutting-edge and highly anticipated technologies today, thanks to its transformative potential for the tech industry.
Given its significance, it’s no surprise that many traders and investors are eager to tap into this emerging field, hoping to benefit from the growth of companies pioneering its development.
In this article, we explore what quantum computing is and why it matters.

TL;DR
Quantum computing uses qubits, which can represent both 0 and 1 at the same time, enabling far more powerful computation than traditional computers.
Key features include superposition, entanglement, and exponential processing power for complex problems.
Top quantum companies include IBM, Microsoft, Amazon (Braket), Google (Alphabet), IonQ, and Rigetti.
Applications span across AI, finance, drug discovery, logistics, and cybersecurity, offering game-changing potential.
What Is Quantum Computing Technology?
Quantum computing is a new type of computing that leverages quantum physics to process information in a completely different way from regular computers. While traditional computers use bits that can be either 0 or 1, quantum computers use quantum bits, or qubits, which can be both 0 and 1 at the same time thanks to a property called superposition.
They also use entanglement, which means qubits can be connected in a way where the state of one instantly affects the state of another.
These special abilities allow quantum computers to solve certain problems much faster than normal computers, such as complex calculations, simulations for drug discovery, or cracking very advanced codes. It’s like going from a car to a plane in terms of speed.
What Are Quantum Computing Companies?
Quantum computing companies are organisations engaged in the research, development, and commercialisation of quantum computing technologies, encompassing both hardware and software solutions. These companies work on building quantum processors, developing quantum algorithms, creating software platforms, and offering cloud-based quantum computing services. Their goal is to harness the power of quantum mechanics to solve complex problems that are beyond the capabilities of classical computers, with potential applications across industries such as pharmaceuticals, finance, cybersecurity, logistics, and materials science.
Biggest Quantum Computing Companies
Some of the top quantum computing companies in the world include the following:
IBM

Microsoft
Microsoft is focused on creating a full-stack quantum computing platform called Azure Quantum. It partners with other hardware companies and is also developing its own topological qubit, a unique type of stable qubit. It emphasises a hybrid cloud approach and quantum software development tools.
Amazon
Amazon offers quantum computing through Amazon Braket, a cloud service on AWS that allows users to run quantum algorithms on different quantum hardware from multiple providers. Amazon is also researching its own quantum technologies through the AWS Center for Quantum Computing.
Alphabet
Google’s quantum division, Google Quantum AI, made headlines in 2019 by claiming to achieve "quantum supremacy." It’s building its own superconducting quantum processors and is working toward building a large-scale, error-corrected quantum computer.
IonQ
IonQ builds quantum computers using trapped ion technology, which uses individual atoms as qubits. It was one of the first pure quantum hardware companies to go public and offers cloud access to its systems via AWS, Azure, and Google Cloud.
Rigetti
Rigetti is a startup focused on building superconducting quantum processors and integrating them into a hybrid classical-quantum computing system. It also provides cloud-based access to its quantum computers through its platform called Forest.
The Future of Quantum Computing
Quantum computing is undergoing a pivotal transformation, fueled by rapid technological progress, expanding real-world applications, and significant investment from both governments and private industry. With the global market expected to surge from $1.8 billion in 2025 to as much as $65 billion by 2030, momentum is being driven by major breakthroughs in scalable, low-error qubit systems, the rise of hybrid quantum-classical models, and the development of practical quantum networks. Sectors such as artificial intelligence, drug discovery, finance, and cybersecurity are beginning to leverage quantum advantages for faster computation, advanced simulations, and enhanced encryption. While challenges like error correction, scalability, and workforce development remain, increased access via cloud-based platforms and a growing focus on tailored, industry-specific solutions mark 2025 as a key turning point in the evolution of quantum computing.

FAQs:
What makes quantum computing different from classical computing?
Quantum computers use qubits instead of bits. Unlike bits, which can only be 0 or 1, qubits can be in multiple states at once (superposition) and can be entangled for faster, more complex processing.
Why are investors interested in quantum computing?
Quantum computing is expected to revolutionise industries such as AI, finance, healthcare, and cybersecurity. As the technology matures, early investors hope to benefit from the rapid growth of companies that are leading its development.
Which companies are leading in quantum computing?
Some of the top players include IBM, Microsoft, Amazon, Alphabet (Google), IonQ, and Rigetti. Each is developing different aspects of quantum technology, from hardware and cloud platforms to algorithms and software tools.
