Thorlabs has introduced the latest addition to its product line up for the field of quantum photonics, a correlated photon-pair source
The technique uses entangled photons to overcome the limitations of conventional holographic approaches
Taking advantage of collective quantum effects has enabled the so-called first quantum revolution in the 20th century for technologies such as nuclear magnetic resonance spectroscopy, magnetic resonance imaging, and the development of transistors, LEDs, solar panels, and lasers. Today, amid the second quantum revolution new sensing schemes offer higher sensitivities and better resolution thanks to the possibility to detect and control individual quantum states in microscopic systems like atoms, quantum dots, or color centers.
Optical methods are helping defeat criminals seeking to hack biometric identification, finds Andy Extance
Successful clinical translation depends on funding robust trials – and greater trust between developers and end-users, finds Jessica Rowbury
Carlos Lee talks to Petr Tůma about the growth of Czech-based 4isp, a distributor of HSG lasers, including its move to a leasing model and how it works with Chinese manufacturers
