The Fredkin gate takes us one step closer to quantum computers

In late March, reports came out that researchers from Griffith University and the University of Queensland demonstrated the Fredkin gate, also known as the controlled-SWAP gate. First conceived by American digital physicist Edward Fredkin, the Fredkin gate is designed to exchange values between qubits in a quantum computing system based on a value of a third qubit. The Fredkin gate is perhaps a foundational component to quantum computers, replacing circuits requiring five logic operations with circuitry which takes advantage of the quantum principle of entanglement.
