Spin Glasses and Computational Complexity
Speaker(s): Daniel Gottesman
Abstract: A system of spins with complicated interactions between them can have many possible configurations. Many configurations will be local minima of the energy, and to get from one local minimum to another requires changing the state of very many spins. A system like this is called a spin glass, and at l... read more

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.
