Entanglement dynamics under decoherence: from qubits to qudits
André R. R. Carvalho, Florian Mintert, Stefan Palzer +1
We investigate the time evolution of entanglement for bipartite systems of arbitrary dimensions under the influence of decoherence. For qubits, we determine the precise entanglemen…
Quantum Noise Locking
Kirk McKenzie, Eugeniy Mikhailov, Keisuke Goda +5
Quantum optical states which have no coherent amplitude, such as squeezed vacuum states, can not rely on standard readout techniques to generate error signals for control of the qu…
Photothermal Fluctuations as a Fundamental Limit to Low-Frequency Squeezing in a Degenerate Optical Parametric Amplifier
Keisuke Goda, Kirk McKenzie, Eugeniy E. Mikhailov +3
We study the effect of photothermal fluctuations on squeezed states of light through the photo-refractive effect and thermal expansion in a degenerate optical parametric amplifier…
Wave mechanics without gauge fixing
A. M. Stewart
By using the multipolar gauge it is shown that the quantum mechanics of an electrically charged particle moving in a prescribed classical electromagnetic field (wave mechanics) may…
Quantum Computation with Diatomic Bits in Optical Lattices
Chaohong Lee, Elena A. Ostrovskaya
We propose a scheme for scalable and universal quantum computation using diatomic bits with conditional dipole-dipole interaction, trapped within an optical lattice. The qubit stat…
