Globally controlled universal quantum computation with arbitrary subsystem dimension
G. A. Paz-Silva, G. K. Brennen, J. Twamley
We introduce a scheme to perform universal quantum computation in quantum cellular automata (QCA) fashion in arbitrary subsystem dimension (not necessarily finite). The scheme is d…
Non-locality of non-Abelian anyons
G. K. Brennen, S. Iblisdir, J. K. Pachos +1
Topological systems, such as fractional quantum Hall liquids, promise to successfully combat environmental decoherence while performing quantum computation. These highly correlated…
Spontaneous emission of atomic systems in the presence of incident fields
Peter G. Brooke
We characterise the spontaneous emission time and direction from small numbers of dipole-coupled two-level atoms (2LAs) in the presence of incident fields. We show how to use adiab…
Demonstrating Heisenberg-limited unambiguous phase estimation without adaptive measurements
B. L. Higgins, D. W. Berry, S. D. Bartlett +3
We derive, and experimentally demonstrate, an interferometric scheme for unambiguous phase estimation with precision scaling at the Heisenberg limit that does not require adaptive…
Decoherence-free quantum information in Markovian systems
Manas K. Patra, Peter G. Brooke
Decoherence in Markovian systems can result indirectly from the action of a system Hamiltonian which is usually fixed and unavoidable. Here, we show that in general in Markovian sy…
Decoherence-free quantum information in the presence of dynamical evolution
Peter G. Brooke, James D. Cresser, Manas K. Patra
We analyze decoherence-free (DF) quantum information in the presence of an arbitrary non-nearest-neighbor bath-induced system Hamiltonian using a Markovian master equation. We show…
