Scientist has got success in linking the quantum properties of two separated ions using microwaves to manipulate them. This is currently done with the help of laser beams and now this advancement can shrink the size of quantum computers. This research has been done at NIST (National Institute of Standards and Technology) which has been published in Nature.
Microwaves have been used previously in manipulating single ions, but this is the first time when scientist from NIST used this on two separated ions places just 30 micrometers away. This kind of process give rise to a quantum mechanism which is crucial for information transportation and error correction in Quantum computers.
The mentioned experiment use desktop scale table of lasers and very small mirrors and lenses that are around 1/10 th of the sizes that are actually used these days. Microwave components can be easily expanded to make a practical quantum computer system. Also by using microwaves they were able to reduce errors that are however caused by using laser beams due to incorrect pointing issues and power.
Scientist Dietrich Leibfried said that it may be possible to have a quantum computer of a size of smart phone in near future. More powerful quantum computer can be made up to a size of Desktop PC.

If the current research of Dr. Ashutosh Saxena of Cornell’s Personal Robotics Laboratory becomes successful then Robots of future will learn to manipulate objects and will develop the ability of generalization. This learning procedure will help Robots to adapt according to new environments.
The main theory behind this is the use of machine learning programming which leads to observation of events by Robots and find commonalities. For an example a robot will see different cups, learn the common characteristics of cups and will then identify cups in future no matter what size and shape they will have. This kind of process will also teach robots to handle cups correctly.
According to Saxsena, these new robots would be able to make decisions like how to place cups on different places. Like a cup will be placed upright on table while upside down in dishwasher. Robots will get training of placing strategies and will be able to apply then on other objects by the process of generalization.
In testing process scientists placed different things like a plate, mug, glass, bowl, spoon and some other objects at different surfaces like on flat surface, hook, stemware holder etc. Robots then tested the suitable locations for placement of these objects after studying the environment and gave priority to best locations to place an object.
After such training Robot placed objects 98% correct at previously seen environment and objects. This accuracy was 95% for new objects and environments and that can be improved further by longer periods of training.
The base of all this is the contextual relations in 3-Dimensions.
Although making a Robot that acts just like humans will take long time but by making Robots like these is a giant leap in Robotics.
