Scientists have observed traveling three-photon bound states in a quantum nonlinear medium, a phenomenon that could help further the use of photons in quantum computing. Researchers from the Massachusetts Institute of Technology (MIT) and Harvard University, in conjunction with scientists from the University of Maryland, Princeton University and the University of Chicago, found that when they excited a cloud of rubidium atoms through a sequence of laser pulses they could induce strong interactions between propagating photons. They tuned the strength of the interaction to make the...Read full articleRelated content from Photonics MediaARTICLESSilicon Quantum Bits Communicate over Relatively Long DistancesA Princeton University research team has shown that silicon quantum bits (qubits), mediated by a microwave photon, can interact even when spaced relatively far apart on a computer chip.

In particular, it’s necessary to determine how variations in process parameters affect end results, so that acceptable process input and operating ranges can be determined.Materials processing with lasers is actually a broad term for a diverse range of applications. The major categories of these uses, and the lasers that service them, are summarized Table 1. At one...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookVibration Control: Limiting Mechanical Noise: Vibration control plays a critical role in research and industry. Mechanical noise, for example, can obscure high-resolution images and affect the quality of nanotechnology processes. Fortunately, vibration can be controlled through proper experimentation, process design, and the use of specialized equipment.In general, there are three common approaches to reducing mechanical excitation of photonic systems. The first is identifying the sources of vibration and implementing ways to eliminate or reduce...Photonics HandbookMachine Vision Cameras: Making the Right Selection: Improvements and affordability have broadened the use of vision systems for inspection, but several factors should be considered before making a purchase.Technological advances have resulted in new, higher-quality sensors that enable machine vision cameras to deliver greater features and functionality at a lower cost than ever before.
