(Press-News.org) BELLINGHAM, Washington, USA – A new special section on single-photon detection, generation, and applications in Optical Engineering highlights research on technologies with applications in areas as diverse as space exploration and quantum computing, furthering the field by providing more accurate measurement methods and new analysis techniques. The peer-reviewed journal is published by SPIE, the international society for optics and photonics, in print and in the SPIE Digital Library.
The section appears in the August issue, and include nine articles and an editorial outlining the history and future of these technologies.
Each paper describes a new or improved single-photon detection strategy and its applications, including optical time transfer experiments, space missions, superconducting nanowire single-photon detection systems, quantum optics, quantum key distribution, high-volume silicon photomultiplier production, and physical quantum random number generation.
"Beyond the fundamental metrology of single-photon devices, the use of single photons can provide accuracy enhancements in numerous situations involving optical measurements," note special section guest editors Alex McIntosh (MIT Lincoln Lab) and Mark Itzler (Princeton Lightwave Inc.) in their editorial.
Among the benefits of new technologies and methods described in the special section guest are high detection efficiency, low dark-count rate, precise picosecond-scale timing resolution, and fast nanosecond-scale reset times which endow superconducting nanowire single-photon detectors (SNSPD) devices with the highest performance single-photon detection demonstrated to date, the editors write.
Three of the nine articles are open access:
In "Review of superconducting nanowire single-photon detector system design options and demonstrated performance," Eric Dauler of MIT Lincoln Lab and co-authors compare and describe new and future applications of optical coupling, electrical readout, and SNSPD design with system detection efficiencies of greater than 70 percent. With optical interfaces based on fiber coupling, these detectors are very effective, and further advancements will allow for larger arrays and even higher-performance systems.
In "Photon counting detector for high-repetition-rate optical time transfer providing extremely high data yield," Josef Blazej of the Czech Technical University and co-authors describe development of a new photon counting detector yielding 50 percent or greater data yields. Operational in the vacuum of space, this detector might be used for optical time transfer experiments on the single-photon signal level or in space exploration missions.
In "Metrology of single-photon sources and detectors: a review," Christopher Chunnilall of the UK National Physical Lab and co-authors review the numerous advancements and applications of single-photon generation and detection technologies. These technologies will assist in the development of new quantum optical technologies including sensing, computing, and simulation.
Other papers include:

No sign of health or nutrition problems from GMO livestock feed, study finds
2014-09-26
A new scientific review from the University of California, Davis, reports that the performance and health of food-producing animals consuming genetically engineered feed, first introduced 18 years ago, has been comparable to that of animals consuming non-GE feed.
The review study also found that scientific studies have detected no differences in the nutritional makeup of the meat, milk or other food products derived from animals that ate genetically engineered feed.
The review, led by UC Davis animal scientist Alison Van Eenennaam, examined nearly 30 years of livestock-feeding ...
Exploring the connection between empathy, neurohormones and aggression
2014-09-26
Empathy is typically seen as eliciting warmth and compassion—a generally positive state that makes people do good things to others. However, empathy may also motivate aggression on behalf of the vulnerable other. Researchers at the State University of New York at Buffalo, examined whether assessed or elicited empathy would lead to situation-specific aggression on behalf of another person, and to explore the potential role of two neurohormones in explaining a connection between empathy and aggression. The study is published in Personality and Social Psychology Bulletin. ...
Discrepancies in access to new cancer drugs revealed
2014-09-26
Access to potentially life-extending cancer drugs varies significantly in different regions of the world, two new studies show at the ESMO 2014 Congress in Madrid, Spain.
Researchers say the results demonstrate the need for better collaboration between doctors and health authorities on an international scale, to ensure patients have access to the best treatments.
Coordinated action is needed at an international level to ensure new cancer-fighting drugs are approved in a timely manner, oncologists said at the Congress. Their call came after a survey revealed that patients ...
Protein 'map' could lead to potent new cancer drugs
2014-09-26
Imperial chemists have gained fresh insights into how a disease-causing enzyme makes changes to proteins and how it can be stopped.
The scientists hope their findings will help them to design drugs that could target the enzyme, known as N-myristoyltransferase (NMT), and potentially lead to new treatments for cancer and inflammatory conditions.
They have already identified a molecule that blocks NMT's activity, and have identified specific protein substrates where this molecule has a potent impact.
NMT makes irreversible changes to proteins and is known to be involved ...

A bioactive compound found in turmeric promotes stem cell proliferation and differentiation in the brain, reveals new research published today in the open access journal Stem Cell Research & Therapy. The findings suggest aromatic turmerone could be a future drug candidate for treating neurological disorders, such as stroke and Alzheimer's disease.
The study looked at the effects of aromatic (ar-) turmerone on endogenous neutral stem cells (NSC), which are stem cells found within adult brains. NSC differentiate into neurons, and play an important role in self-repair and ...
Talk therapy -- not medication -- best for social anxiety disorder, large study finds
2014-09-26
While antidepressants are the most commonly used treatment for social anxiety disorder, new research suggests that cognitive behavioral therapy (CBT) is more effective and, unlike medication, can have lasting effects long after treatment has stopped.
Social anxiety disorder is a psychiatric condition characterized by intense fear and avoidance of social situations and affects up to 13 percent of Americans and Europeans. Most people never receive treatment for the disorder. For those who do, medication is the more accessible treatment because there is a shortage of trained ...
Experts call for a moratorium on use of new internet domain .health
2014-09-26
As the Internet Corporation for Assigned Names and Numbers (ICANN) moves forward with plans to launch health-related generic top-level domains (gTLD), such as .health and .doctor, a coalition of health policy academics and clinicians are raising concerns about a process they say "favor[s] business interests and the generation of profits over the future integrity of the Health Internet."
In a commentary published in the open access journal Globalization and Health, the authors - led by Tim Mackey of the Global Health Policy Institute – call for a moratorium on use of ...
Viral infection in transplant recipients increases risk of developing damaging antibodies
2014-09-26
Washington, DC (September 25, 2014) — Kidney transplant recipients infected with BK virus are more likely to develop antibodies against their kidney transplants than uninfected patients, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). Future treatment strategies should focus on simultaneously clearing BK infections while protecting against risks of transplant rejection.
Many people are infected with BK virus, and it rarely causes disease. However, for transplant recipients and others who take immunosuppressive ...
