The number of start-ups in the field of quantum computing has increased sharply worldwide in recent years. In 2015, there were ** start-ups in the computer technology sector in the United States; by 2022, that number had grown to **. In the EU, the number of start-ups active in quantum technology rose from **** in 2015 to ** in 2022. Of the ** quantum technology start-ups in Europe, * are based in Germany.

What is quantum computing?

Whereas the data processing of a classical computer can be explained by the principles of classical physics, the emerging technology of quantum computing is based on the laws of quantum physics. The smallest unit of information in classical computers is the bit, which can only have a value of either 0 or 1. A quantum computer, by contrast, uses quantum bits, called qubits. These can exist in superposition and become entangled with one another, allowing them to take on a vast range of states between 0 and 1. The unique properties of quantum physics make it possible to solve complex problems. With the Hummingbird processor with 65 qubits, IBM developed in 2020 the most powerful quantum computer so far measured by achieved qubits.

Quantum computers

The quantum computer is the prerequisite for most of the things that can be achieved with quantum technology. Quantum computers can perform multiple computations at the same time that would take even today’s supercomputers decades. Its market volume is expected to total roughly *** billion U.S. dollars in the coming years.
