Bounds on the entanglability of thermal states in liquid-state nuclear magnetic resonance
Terri M. Yu, Kenneth R. Brown, Isaac L. Chuang
The role of mixed state entanglement in liquid-state nuclear magnetic resonance (NMR) quantum computation is not yet well-understood. In particular, despite the success of quantum…
NMR Quantum Information Processing
Chandrasekhar Ramanathan, Nicolas Boulant, Zhiying Chen +3
Nuclear Magnetic Resonance (NMR) has provided a valuable experimental testbed for quantum information processing (QIP). Here, we briefly review the use of nuclear spins as qubits,…
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…
Entanglement in the stabilizer formalism
David Fattal, Toby S. Cubitt, Yoshihisa Yamamoto +2
We define a multi-partite entanglement measure for stabilizer states, which can be computed efficiently from a set of generators of the stabilizer group. Our measure applies to qub…
