Universal Control of Nuclear Spins Via Anisotropic Hyperfine Interactions

Jonathan S. Hodges, Jamie C. Yang, Chandrasekhar Ramanathan +1

We show that nuclear spin subsystems can be completely controlled via microwave irradiation of resolved anisotropic hyperfine interactions with a nearby electron spin. Such indirec…

Symmetrised Characterisation of Noisy Quantum Processes

Joseph Emerson, Marcus Silva, Osama Moussa +5

A major goal of developing high-precision control of many-body quantum systems is to realise their potential as quantum computers. Probably the most significant obstacle in this di…

Dynamics and Control of a Quasi-1D Spin System

Paola Cappellaro, Chandrasekhar Ramanathan, David G. Cory

We study experimentally a system comprised of linear chains of spin-1/2 nuclei that provides a test-bed for multi-body dynamics and quantum information processing. This system is a…

Simulations of Information Transport in Spin Chains

Paola Cappellaro, Chandrasekhar Ramanathan, David G. Cory

Transport of quantum information in linear spin chains has been the subject of much theoretical work. Experimental studies by nuclear spin systems in solid-state by NMR (a natural…

Fidelity enhancement by logical qubit encoding

Michael K. Henry, Chandrasekhar Ramanathan, Jonathan S. Hodges +4

We demonstrate coherent control of two logical qubits encoded in a decoherence free subspace (DFS) of four dipolar-coupled protons in an NMR quantum information processor. A pseudo…

Signatures of incoherence in a quantum information processor

Michael K. Henry, Alexey V. Gorshkov, Yaakov S. Weinstein +8

Incoherent noise is manifest in measurements of expectation values when the underlying ensemble evolves under a classical distribution of unitary processes. While many incoherent p…
