Electrical Quantum Circuits - from Topology to Quantum Information:
Different Routes to the Development of the Quantum Computer

All over the world, different paths are being taken to develop a quantum computer. Companies such as Microsoft, Google, Intel, IBM and Rigetti are studying sometimes very diverse, sometimes related concepts for the elementary building blocks of a quantum computer.

In addition, further variants are being investigated at numerous research institutes around the world. The different approaches range from semiconductors, superconductors and diamond crystals to atom and ion traps. In these categories, different variations exist once again, so that ultimately no two designs are alike.

Institute for Quantum Information (IQI)

Founded in 2011, the institute pursues a variety of topics in both practical and fundamental quantum information science. Solid state quantum information processing devices, either based on spins or superconductors, are a real possibility for the future.

Our theoretical work seeks to find improved ways for these qubits to function and to work together in a system. These goals motivate very fundamental studies in a diverse set of areas, including many-body physics, the theory of quantum error correction codes, the theory of quantum control, and quantum computational complexity.
