What is Quantum technology?
Quantum Technology is based on the principles of Quantum mechanics to describe nature at the scale of atoms and elementary particles.
Using quantum superposition, a set of unbreakable codes or super-speedy information processing, quantum computers are able to mimic several classical computers working in parallel
It revolves around exploiting the properties of an individual, or a few fundamental particles, to achieve revolutionary changes in technology. One example is the property known as entanglement.
What is quantum entanglement?Who has already utilizing it?
Quantum entanglement is a quantum mechanical phenomenon in which the quantum states of two or more objects have to be described with reference to each other, even though the individual objects may be spatially separated. This leads to correlations between observable physical properties of the systems.
When two objects, say two particles of light, also called photons, are in an entangled state, any changes made to the state of one, for example, its spin, are reflected in the other particle, however far they move from each other without breaking the entanglement. If developed, this property can be used to transmit a message at a very high level of secrecy from one point to another.
China has recently demonstrated quantum communication technology using the satellite Micius, by conducting a secret conference between two ground stations about 1,120 km apart.
