In a major breakthrough in quantum computing, scientists from Griffith University and the University of Queensland in Australia announced Monday that they had found a way to simplify a complicated logic operation by creating a quantum “Fredkin gate” for the first time ever. The development, detailed in the journal Science Advances, could bring fully functional quantum computers closer to reality.Could a Fredkin gate be the next quantum leap forward for computing? - CSMonitor.com
“Much like our everyday computer, the brains of a quantum computer consist of chains of logic gates, although quantum logic gates harness quantum phenomena,” Raj Patel, from the Griffith University’s Centre for Quantum Dynamics, said in a statement. “Similar to building a huge wall out lots of small bricks, large quantum circuits require very many logic gates to function. However, if larger bricks are used the same wall could be built with far fewer bricks.”

Scientists have built a new computer chip capable of overcoming one of the key obstacles to building quantum computers. The quantum Fredkin gate is a vital piece of quantum computing that was previously too complex to build, but scientists have found a way to simplify the process.
By simplifying one of the basic parts of a quantum computer, the team behind the breakthrough hopes it will make building functional quantum computers more feasible and unlock the massive potential behind the advanced computers.

Building such a powerful computer, however, is currently hampered by a range of obstacles that scientists have yet to overcome.
One of these obstacles is the need to reduce the number of resources required to efficiently implement processing circuits. A new breakthrough with a new circuit though may bring quantum computing closer to reality.
Essentially, the scientists demonstrated how to build large quantum circuits directly, without having to use numerous small logic gates. That, in turn, puts real quantum computers within closer reach.
Scientists at Florida State University’s National High Magnetic Field Laboratory (MagLab) recently reported a breakthrough with similar promise by minimizing qubits' susceptibility to magnetic disturbances.
The new research was published last week in Science Advances.
