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.
