Quantum technology, also known as quantum information technology, seeks to harness the peculiar laws of quantum mechanics to build more powerful tools for processing information.
In a new book which aims to explain this entanglement, as well as quantum mechanics, one of the most difficult and obscure subjects in all of science, author Philip Ball has tried to give words to the complex mathematical equations of the theory.
Researchers at Delft University of Technology have created a quantum circuit that enables them to listen to the weakest radio signal allowed by quantum mechanics. This new quantum circuit opens the door to possible future applications in areas such as radio astronomy and medicine (MRI).
Quantum mechanics holds a unique place in the history of physics.
According to quantum mechanics their structure should be exactly the same as their matter counterparts.

Their experiment, described in a study published in the (http://journals.aps.org/prl/abstract/10.1103/PhysRevLett.117.023001) Physical Review Letters , deals a significant blow to hopes of reconciling classical physics and quantum mechanics, since a subatomic particle's quantum spin is one of the most intrinsic properties it possesses.
The uncertainty principle in quantum mechanics states that both the position and momentum of a subatomic particle cannot be simultaneously measured, but observation fixes that particle's position or momentum.
This shows the direct mathematical compatibility of more classical treatments (Hamiltonian) and quantum mechanics through deformation (with parameter h/S) and perhaps gives a real-world, easily understood relationship between the two through the common sense term "deformation".
