ETH Zurich and the Paul Scherrer Institute (PSI) establish a joint centre for the development of quantum computers. Its aim is to advance the realization of quantum computers based on both ion traps and superconducting components. ETH Zurich provides 32 million francs for this centre, which will host around 30 researchers.
They are bulky, error-prone and difficult to build — the genesis of quantum computers is reminiscent of the birth of conventional computers. Currently, researchers at ETH Zurich operate quantum computers with up to 17 quantum bits, so-called qubits. For quantum computers to be able to unfold their full potential one day, however, devices with thousands, if not hundreds of thousands, of qubits are needed.
The next step is to develop quantum...
