Identifying Stabilizer States
Speaker(s): Daniel Gottesman
Abstract: Suppose you are given m copies of an unknown n-qubit stabilizer state. How many copies do you need before you can figure out exactly what state it is? Just to specify the state requires about n^2/2 bits, so certainly m is at least n/2. Using only single-copy measurements, we show how to identify the... read more

A simple proof of the threshold for fault-tolerant quantum computation
Speaker(s): Daniel Gottesman
Abstract: One of the central critical results in the theory of fault-tolerant quantum computation is that arbitrarily long reliable computation is possible provided the error rate per gate and per time step is below some threshold value. This was proved by a number of groups, but the detailed published proofs... read more
