As we stand at this critical juncture, it is essential to understand both the progress made and the obstacles that remain on the path toward the widespread adoption of quantum technologies.
Quantum computing leverages the principles of quantum mechanics, the fundamental theory in physics that describes nature at the smallest scales of energy levels of atoms and subatomic particles. Unlike classical computers, which rely on bits as the smallest unit of information, quantum computers use qubits. Qubits can exist in multiple states simultaneously (a property known as superposition), and they can be entangled, meaning the state of one qubit can depend on another, no matter the distance between them. These properties allow quantum computers to process a vast number of possibilities simultaneously, making them extraordinarily powerful for certain types of calculations.
In 2024, the quantum computing landscape is defined by a mix of enthusiasm and caution. The potential of quantum computers to revolutionize fields such as cryptography, materials science, pharmaceuticals, and artificial intelligence has never been clearer. However, realizing this potential requires overcoming significant technical hurdles, such as increasing the number of qubits while maintaining their coherence, error correction, and the development of new quantum algorithms that can efficiently solve real-world problems.
The momentum in quantum computing is driven by a combination of technological breakthroughs, strategic investments, and collaborations across the public and private sectors.

The Rapid Doubling of Physical Qubits
One of the most remarkable trends in quantum computing is the rapid doubling of physical qubits, which has been occurring every one to two years. This exponential growth mirrors the trajectory of classical computing, famously encapsulated in Moore’s Law, where the number of transistors on a microchip doubles approximately every two years. However, quantum computing operates on an entirely different paradigm, and its progress is measured not just by the sheer number of qubits but by their quality and coherence times.
In the early 2020s, the field witnessed qubit counts in the tens and hundreds, but as of 2024, leading quantum computers are pushing toward thousands of qubits. This increase is crucial because more qubits theoretically mean more computational power, allowing quantum computers to tackle more complex problems. However, merely increasing the number of qubits is not sufficient. The challenge lies in maintaining coherence (the duration for which qubits remain in a superposition state) and reducing error rates, which tend to increase with the number of qubits.
The rapid growth in qubit numbers has been driven by advances in qubit architecture, error correction techniques, and improved materials. Companies are exploring various types of qubits, including superconducting qubits, trapped ions, and topological qubits, each with its own set of advantages and challenges. Superconducting qubits, for instance, have seen significant improvements in coherence times, thanks to better isolation from environmental noise and more sophisticated error-correcting algorithms.
As qubit numbers continue to grow, the industry is approaching a critical threshold where quantum computers could surpass classical computers in solving specific tasks—this is often referred to as “quantum advantage” or “quantum supremacy.” While achieving quantum supremacy for practical, real-world problems is still a work in progress, the doubling of qubits brings the field ever closer to this pivotal milestone.
