    "abstract": "We show that thresholds for fault-tolerant quantum computation are solely\ndetermined by the quality of single-system operations if one allows for\nd-dimensional systems with $8 \\leq d \\leq 32$. Each system serves to store one\nlogical qubit and additional auxiliary dimensions are used to create and purify\nentanglement between systems. Physical, possibly probabilistic two-system\noperations with error rates up to 2/3 are still tolerable to realize\ndeterministic high quality two-qubit gates on the logical qubits. The\nachievable error rate is of the same order of magnitude as of the single-system\noperations. We investigate possible implementations of our scheme for several\nphysical set-ups.",
