Alternate Scheme for Optical Cluster-State Generation without Number-Resolving Photon Detectors [PDF]

open access: yes, 2007
We design a controlled-phase gate for linear optical quantum computing by using photodetectors that cannot resolve photon number. An intrinsic error-correction circuit corrects errors introduced by the detectors.

All-optical reservoir computing

open access: yesOptics Express, 2012
Reservoir Computing is a novel computing paradigm which uses a nonlinear recurrent dynamical system to carry out information processing. Recent electronic and optoelectronic Reservoir Computers based on an architecture with a single nonlinear node and a delay loop have shown performance on standardized tasks comparable to state-of-the-art digital ...

Cluster state quantum computing in optical fibers [PDF]

open access: yes, 2006
A scheme for the implementation of the cluster state model of quantum computing in optical fibers, which enables the feedforward feature, is proposed. This scheme uses the time-bin encoding of qubits.

Terahertz and Photoelectron Emission from Nanoporous Gold Films on Semiconductors

open access: yesNanomaterials, 2019
Efficient terahertz and photoelectron emission were observed from nano-porous gold (NPG) films deposited on an intrinsic gallium arsenide (GaAs) semiconductor substrate stimulated by femtosecond laser with pulse width of 60 fs.

Optical quantum computation using cluster states [PDF]

open access: yes, 2004
We propose an approach to optical quantum computation in which a deterministic entangling quantum gate may be performed using, on average, a few hundred coherently interacting optical elements (beamsplitters, phase shifters, single photon sources, and ...
