Perhaps people do not realize it, but haptic technology is already in our lives. Vibrating phones, gaming controllers and force-feedback control knobs in cars, like BMW’s iDrive, are examples of this technology. These days, you can turn your phone ring tone off, put it in your purse and still feel that someone is calling you when you get a vibration. On the other hand, the Nintendo Wii video game console has been a new revolution for game lovers. The controller, called Wii, provides vibrations (i.e. when you hit the ball in a tennis game) which enhances the virtual sensation.
Currently, physical prototypes are replaced by virtual or digital prototypes/models (Computer Aided Design - CAD) to avoid building expensive prototypes, especially in the automotive and aeronautics sectors (Figure 2.a). Increasingly, these CAD systems also allow designers and engineers to carry out assembly processes. The use of touch in CAD systems allows operators to feel forces and local stimuli similar to those in real situations, which provides more intuitive manipulation (i.e. check any defect or decide the most appropriate assembly sequence). On the other hand, different designers, which may be situated over a thousand kilometers away, often collaborate in the design and revision of products to lessen time and lower costs. The objective of this thesis is to research and provide solutions for collaborative haptic assembly systems, where several designers in different locations can grasp virtual parts and assemble them into a digital engine or other mechanical parts (Figure 2.b). To achieve it, a Collaborative Haptic Assembly Simulator, called CHAS, was developed, where two designers can collaborate together in real-time. Trials between Labein (Derio, Bizkaia) and Queen’s University Belfast (Northern Ireland) have verified this system. When performing the assembly task, the operator in Bizkaia could assemble a part into another part grasped by the remote operator in Belfast. Furthermore, the operator in Belfast could feel the collisions with the part grasped by the remote operator.
This is a small step towards new systems of collaboration over the Internet, or a new way of interacting over distance. Doctors will have the ability to remotely diagnose and operate on patients, or we will be able to shake hands virtually.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
