Quantum memory stores information in a similar fashion to the way traditional computer memory does, but on individual quantum particles—in this case, photons of light. This allows it to take advantage...
An international team led by the University of Chicago’s Institute for Molecular Engineering has discovered how to manipulate a weird quantum interface between light and matter in silicon carbide alon...

OPTO is organized into eight tracks. Choose a track and click to see the list of conferences.Review conference details by clicking on the titles below. These details include paper titles, authors, sch...
ZnSe quantum dot (QD) semiconductor optical amplifier (SOA) is studied theoretically using net gain for linear Absorption coefficient and linear emission and these results are used to calculate noise ...
We experimentally demonstrated operating original and converted wavelengths flexible wavelength conversion using cross-gain-modulation in a single quantum dot semiconductor optical amplifier with cove...
We report on the generation of an optical clock up to 1.2 THz using a Quantum Dash mode-locked laser and a spectral filter, selecting two or three lines, which are separated by the desired spacing.
We implement an experimental continuous variable quantum key distribution system over 24 km of optical fiber that uses discrete signaling and a continuous wave local oscillator. A secure key rate of 3...
Secure optical transmission experiment is demonstrated using a stream cipher by quantum noise. The bit error rates of a 10Gbit/s signal through 360km fiber for authentic receiver and eavesdropper are ...
We propose a simple method for passive preparation of decoy states in quantum key distribution with coherent light. It involves linear optics together with a photo-detector. The performance is compara...
We demonstrate coexistence of classical and quantum signals for quantum key distribution in a DWDM reconfigurable networking environment using a ROADM. We show how the limiting noise mechanism can dep...
A 10 dB input power dynamic range advantage is found for amplification of phase-encoded signals with quantum dot SOA compared to low confinement bulk SOA. The effect is attributed to differences in th...
The very recent demonstration of the SECOQC QKD-network convincingly extended single QKD-links to QKD-networks gaining new functionalities. The needed interfaces, protocols and node modules are explai...
An implementation of 1-GHz clocked differential-phase-shift quantum key distribution system is reported.High speed signal generation and its storage were realized by using FPGA. A stable operation was...
