Researchers developed a special type of amplifier that uses a technique known as squeezing to amplify quantum signals by a factor of 100 while reducing the noise that is inherent in quantum systems by an order of magnitude. Their device is the first to demonstrate squeezing over a broad frequency bandwidth of 1.75 gigahertz, nearly two orders of magnitude higher than other architectures.

A team based at the U.S. Department of Energy's (DOE) Argonne National Laboratory has been using ultrafast electron microscopy to investigate tHE strong couplings that arise between gold nanoparticles and layers of graphene. The research will give rise to sensor and quantum device development in the future.

Quantum Devices QML35 Rotary Encoder Replaces RENCO RCML15 Share Article To help fill the needs of former RENCO customers left in the lurch by the obsolescence of the RCML15, Quantum Devices is announcing availability of a drop-in replacement: their QML35 optical rotary encoder. Quantum Devices QML35 rotary encoder is a drop-in replacement for the RENCO RCML15 The QML35 rotary encoder has a similar low profile, same electrical characteristics as the RCML15, and uses the same connector—elimina...

 E-Mail Northwestern University researchers have developed a new approach to quantum device design that has produced the first gain-based long-wavelength infrared (LWIR) photodetector using band structure engineering based on a type-II superlattice material. This new design, which demonstrated enhanced LWIR photodetection during testing, could lead to new levels of sensitivity for next-generation LWIR photodetectors and focal plane array imagers. The work could have applications in earth scien...
