Top 50 Most Promising Startups Quantum computing nears its ‘ChatGPT moment’ From theory to infrastructure, the industry begins its shift toward real-world deployment, with Israeli startups playing a key role. The “ChatGPT moment,” the breakthrough into the mainstream, has not yet arrived for the world of quantum computing, but 2026 is emerging as the year in which the next technological revolution begins to move from theory to business. This does not mean quantum computers are becoming fully commercial yet, but if 2025 was the year of high expectations, the current year is shaping up to be the one in which the infrastructure is laid. From here on, the focus shifts to solving how to build the computers and operating systems that will make quantum an integral part of every data center. In other words: the question of whether the quantum revolution will happen has already been answered. The debate is now about when. Optimists estimate that within two to three years there will already be fairly widespread use of quantum computers; more cautious voices speak of five years. Either way, after nearly three decades of promises about a breakthrough that could solve some of the most complex scientific problems facing humanity, this is a very short timeframe. Quantum computers differ from the conventional computers we know because they are not based on bits as their basic unit of information, but on qubits. These are complex units of information that do not take a value of 1 or 0 like a regular bit, but can exist in both states simultaneously. This phenomenon, known as superposition, is key to the massive computational power of quantum computers, which do not need to evaluate every possible combination sequentially but can process many possibilities at once. This capability could allow quantum computers to solve problems
