Distinguishing quantum states using Clifford orbits
Richard Kueng, Huangjun Zhu, David Gross
It is a fundamental property of quantum mechanics that information is lost as a result of performing measurements. Indeed, with every quantum measurement one can associate a number…
The Clifford group fails gracefully to be a unitary 4-design
Huangjun Zhu, Richard Kueng, Markus Grassl +1
A unitary t-design is a set of unitaries that is "evenly distributed" in the sense that the average of any t-th order polynomial over the design equals the average over the entire…
Explaining quantum correlations through evolution of causal models
Robin Harper, Robert J. Chapman, Christopher Ferrie +5
We propose a framework for the systematic and quantitative generalization of Bell's theorem using causal networks. We first consider the multi-objective optimization problem of mat…
