A Robust Quantum Random Access Memory
A "bucket brigade" architecture for a quantum random memory of memory
cells needs times of quantum manipulation on control circuit nodes
per memory call. Here we propose a scheme, in which only average times
manipulation is required to accomplish a memory call. This scheme may
significantly decrease the time spent on a memory call and the average overall
error rate per memory call. A physical implementation scheme for storing an
arbitrary state in a selected memory cell followed by reading it out is
discussed.Comment: 5 pages, 3 figure
