Loss tolerance in one-way quantum computation via counterfactual error
correction
Michael Varnava, Daniel E. Browne, Terry Rudolph
abstract: We introduce a scheme for fault tolerantly dealing with losses (or other
"leakage" errors) in cluster state computation that can tolerate up to 50%
qubit loss. This is achieved passively using an adaptive strategy of
measurement - no coherent measurements or coherent correction is required.
Since the scheme relies on inferring information about what would have been the
outcome of a measurement had one been able to carry it out, we call this
"counterfactual" error correction.

- Published version - much revised and with a new title. Here we now
focus solely on the general aspects of the protocol - a much expanded and
improved discussion of its application in linear optical quantum computation
can now be found in quant-ph/0702044
