Stabilizing qubit coherence via tracking-control
Daniel A. Lidar, Sara Schneider
We consider the problem of stabilizing the coherence of a single qubit subject to Markovian decoherence, via the application of a control Hamiltonian, without any additional resour…
Long-range entanglement generation via frequent measurements
Lian-Ao Wu, Daniel A. Lidar, Sara Schneider
A method is introduced whereby two non-interacting quantum subsystems, that each interact with a third subsystem, are entangled via repeated projective measurements of the state of…
Diagnosis, prescription and prognosis of a Bell-state filter by quantum process tomography
M. W. Mitchell, C. W. Ellenor, S. Schneider +1
Using a Hong-Ou-Mandel interferometer, we apply the techniques of quantum process tomography to characterize errors and decoherence in a prototypical two-photon operation, a single…
Multipartite Classical and Quantum Secrecy Monotones
N. J. Cerf, S. Massar, S. Schneider
In order to study multipartite quantum cryptography, we introduce quantities which vanish on product probability distributions, and which can only decrease if the parties carry out…
Entanglement in the Dicke model
S. Schneider, G. J. Milburn
We show how an ion trap, configured for the coherent manipulation of external and internal quantum states, can be used to simulate the irreversible dynamics of a collective angular…
Decoherence and fidelity in ion traps with fluctuating trap parameters
S. Schneider, G. J. Milburn
We consider two different kinds of fluctuations in an ion trap potential: external fluctuating electrical fields, which cause statistical movement (``wobbling'') of the ion relativ…
