Bidirectional coherent classical communication
Aram W. Harrow, Debbie W. Leung
A unitary interaction coupling two parties enables quantum communication in both the forward and backward directions. Each communication capacity can be thought of as a tradeoff be…
Efficient Quantum Circuits for Schur and Clebsch-Gordan Transforms
Dave Bacon, Isaac Chuang, Aram Harrow
The Schur basis on n d-dimensional quantum systems is a generalization of the total angular momentum basis that is useful for exploiting symmetry under permutations or collective u…
Arbitrarily accurate composite pulses
Kenneth Brown, Aram Harrow, Isaac Chuang
Systematic errors in quantum operations can be the dominating source of imperfection in achieving control over quantum systems. This problem, which has been well studied in nuclear…
Universal quantum data compression via gentle tomography
Charles H. Bennett, Aram W. Harrow, Seth Lloyd
Quantum state tomography--the practice of estimating a quantum state by performing measurements on it--is useful in a variety of contexts. We introduce "gentle tomography" as a ver…
