"Key to the future"
Quantum computer from Lower Saxony
The first quantum computer for Germany is to be built in Lower Saxony. The state, research institutions and universities expect it to be operational by the end of 2025.
Its potential is considered huge - the state of Lower Saxony wants to develop a quantum computer for Germany together with universities and research institutes. To this end, the expertise of over 400 scientists from the institutes involved in the 'Quantum Valley Lower Saxony' research network is to be pooled. On Monday (30.08. from 12.00 noon), Lower Saxony's Science Minister Björn Thümler will visit quantum physics research locations in Hanover and Braunschweig - to get a first impression. Quantum technology is a "key to the future", said the CDU politician in February.
The aim is to launch the first quantum computer in the country by the end of 2025. In so-called ion trap technology, ions, i.e. charged atoms, are used as the basic computing unit of the computer - an ion is a qubit. These ions are trapped with the help of electric fields and controlled by radio waves and laser beams.
Unlike conventional computers, a quantum computer does not store information as bits, which can only assume two possible states, namely one or zero. A qubit of a quantum computer can also assume all states in between. Therefore, the amount of information that a quantum computer can store and process increases exponentially with the number of qubits. The new quantum computer is expected to have 50 qubits. According to Thümler, 220 million euros have been invested in quantum research in Lower Saxony over the past ten years.
