When we first began tracking successful experiments of quantum in Quantum Computing, Trends 2017, computational operations executed on a very small number of quantum bits. Recently, more companies have been moving from the lab to engineering development and by 2025, quantum computing moved from theory to real-world impact in finance (risk, optimization), drug discovery (molecular simulation), materials science, and logistics (routing), with early returns on investment seen by companies like Ford, J.P. Morgan, and Amazon.
In traditional silicon computers, data is represented in binary bits that are always in one of two states: either a 1 or a 0. However, in a quantum computer each quantum bit, or “qubit,” can represent both a 1 and a 0 at the same time through a principle called superposition. What this means is that a quantum computer can perform multitudes of calculations simultaneously; harnessing millions of qubits could, in a matter of minutes, process data and solve problems that would be impossible for today’s fastest supercomputers.
In 2025, foremost companies announced new quantum chips such as Willow (from Alphabet), Majorana 1 (Microsoft), Nighthawk/Loon (IBM), and Ocelot (Amazon). Many of these developments are focused on efficient error correction and scaling to accelerate development of practical, fault-tolerant quantum computers. Another important step forward was when Google announced the development of the “Quantum Echoes” algorithm that demonstrated verifiable quantum advantage, meaning it could be repeated on another quantum computer. In this case, a benchmark computation that would take a classical supercomputer an estimated 10 septillion (1 followed by 25 zeros) years was completed in under five minutes on the Willow chip.
The implications of large-scale quantum computers will be staggering. With such orders of magnitude of improvement in computing power, expect to see leaps forward in machine learning, artificial intelligence, and simulation modelling. At the same time, quantum computing could pose a threat to traditional encryption security measures that operate on the fundamental assumption that the encryption is too complex to break in a reasonable amount of time, given prevailing computing speeds.
While it’s still early days and many challenges exist in the development of Quantum Computing, we cannot help but imagine the possibilities, which could have a fundamental disruptive impact on the current technology market as we know it.
