"On the noise resilience of quantum algorithms" by Luis Pedro Garcia-Pintos

Speaker: Luis Pedro Garcia-Pintos, Los Alamos National Laboratory Title: On the noise resilience of quantum algorithms Abstract: Current quantum computers have advanced enough that they can implement operations in many different ways. This raises the problem of identifying the best implementation of a quantum operation. The most common and intuitive approach is to consider the ones with the shortest runtime or minimum circuit complexity. I will present an alternative approach that aims for noise-resilient algorithm implementations. To do so, I introduce a general and simple framework to characterize a quantum system’s resilience to noise. Perhaps counter to intuition, the protocols with the shortest runtimes are not always the most resilient. I will also show how quantifying a circuit’s noise resilience can be used to design resilient algorithms, which can solve more complex instances of a problem under a given noise level.
