Promising progress in research into quantum computers more powerful than supercomputers

 



Scientists are one step closer to building 'quantum' computers that are said to be more powerful than today's most advanced  supercomputers and could change our lives.


Quantum computers use the unusual properties of atomic particles :


These quantum particles can exist in two different places at the same time and can surprisingly communicate with each other  despite the distance of millions of miles, meaning that what one is doing can be done by the other at the same time. 


A team at the University of Sussex has exchanged quantum information between two computer chips at record speed and precision.


Computer scientists have been trying to build an efficient quantum computer for more than 20 years. Companies like Google, IBM and Microsoft

have built simple machines. But Professor Winfried Hensinger, head of the research at the University of Sussex, says the new development paves the way for systems that can solve real-life problems that even today's best computers are unable to do.


Today's computers solve problems simply, one calculation at a time.


In the quantum world, particles can exist in two places at the same time, and researchers want to use this feature to build computers  that can solve multiple calculations or problems at the same time.


Quantum particles can surprisingly communicate with each other and copy each other's actions, even if they are millions of miles away  at the same time. And this feature can be used to build powerful computers.


A major hurdle so far has been transferring quantum information between two chips quickly and accurately, as doing so often results in degraded information quality and errors.

Vegetables that are actually fruits

Image
We all know the identity of the vegetables and fruits we use in our daily life, but did you know that there are some  vegetables that are actually fruits ? Actually, the botanical explanation that distinguishes between fruits and vegetables is different. According with the principles of botany, a fruit is defined through the soft pulp produced by the flower of a plant itself . Corn : Corn is also technically a fruit. Cucumber : Cucumber is also not a vegetable but a fruit, cucumbers are the fruit of a plant belonging to the family of fruit plants like watermelon and cantaloupe. Okra : Yes, this seed-rich vegetable is basically a fruit. Tomato : Many debates about tomatos for a long time that it is difficult to consider that is fruit or a vegetable. In 1983, the US Supreme Court also declared as a vegetable in the case, but asked by some botanists , they say tomato is a vegetable. Fruit is what people consider a vegetable. Bitter gourd : If you don't like eating this vegetable, mayb...
