According to a new study that has been done by Australian researchers it has been deduced that the first ever quantum Fredkin gate has been built, it is basically a logic gate that is key to quantum computing . This will be responsible to operate on the photonic qubits rather than regular bits.

According to the scientists and researchers at the University of Queensland and Griffith University  they has totally simplified the complex logic behind quantum computing to take full power on quantum. They have removed all the problems and issues in the way of quantum and that is a way powerful lead out in the segment.  A Fredkin (or controlled-SWAP) gate will be swapping the  three inputs into three outputs, henceforth changing the value of two qubits, from 1 to 0 or vice versa depending on the value of the third.
