Quantum communication using a bounded-size quantum reference frame
Stephen D. Bartlett, Terry Rudolph, Robert W. Spekkens +1
Typical quantum communication schemes are such that to achieve perfect decoding the receiver must share a reference frame with the sender. Indeed, if the receiver only possesses a…
Spin lattices with two-body Hamiltonians for which the ground state encodes a cluster state
Tom Griffin, Stephen D. Bartlett
We present a general procedure for constructing lattices of qubits with a Hamiltonian composed of nearest-neighbour two-body interactions such that the ground state encodes a clust…
Identifying phases of quantum many-body systems that are universal for quantum computation
Andrew C. Doherty, Stephen D. Bartlett
Quantum computation can proceed solely through single-qubit measurements on an appropriate quantum state, such as the ground state of an interacting many-body system. We investigat…
