CRYTERION · Cryogenic Traps for Entanglement Research with Ions

Quantum computers offer a fundamentally new way of information processing. Within the scope of this proposal, quantum information processing with an ion trap quantum computer will be investigated. With the new combination of cryogenic technology and ion traps for quantum computing we intend to build a quantum information processor with strings of up to 50 ions and with two-dimensional ion arrays for an investigation of deterministic many-particle entanglement. The cryogenic traps will be applied for quantum simulations, for fundamental investigations concerning large-scale entanglement and for precision measurements enhanced by quantum metrology techniques employing entangled particles.
