I’ve been at the Australian Institute of Physics (AIP) Congress here in Brisbane all this week. Yesterday I gave a talk on “Error tolerance and tradeoffs in loss- and failure-tolerant quantum computing schemes”.

In this talk I discussed observations we previously made in quant-ph/0603130, where we noted that many recent loss-tolerant protocols for performing quantum computing in the presence of qubit loss and gate failure have the undesired side-effect that they magnify the effects of depolarizing noise.
