Quantum Computing in Silicon has just made a major breakthrough. 99% efficiency?

Last November, we brought you two major quantum computing breakthroughs. First, the US Quantum Economic Development Consortium revealed the results of benchmarking experiments showing how an advanced error suppression method increased the success rate of quantum computing algorithms on real hardware by an unprecedented 2500%.

Second, engineers at Stanford University demonstrated a new, simpler but more advanced design for a quantum computer that could finally make practical versions of the machine a reality. The new design saw a single atom get entangled in a series of photons, allowing it to process and store more information, as well as operate at room temperature, an impressive feat.

Now researchers at the University of South Wales (UNSW) have taken a huge step to prove that near-flawless quantum computing is possible and will soon become a reality.

UNSW Professor Andrea Morello, who led the work, stated: Phys.org That “Today’s publication in Nature shows that our operations were 99 percent flawless.”

“When the errors are so rare, it becomes possible to detect them and correct them when they occur. This shows that it is possible to build quantum computers that have enough scale and enough power to handle meaningful calculations. This piece research is an important milestone on the journey that will take us there.”

Morello had already managed to store quantum information in silicon for 35 seconds, a time equivalent to an eternity in the quantum world. But there was one problem: Morello’s approach involved isolating the qubits, making it impossible for them to communicate with each other to perform calculations.

In his new trials, Morello became pregnant with: an electron encompassing two nuclei of phosphorus atoms that could circumvent the problems encountered in his first efforts. In fact, the new method makes the quantum breakthrough compatible with today’s broader semiconductor industry. Well, that’s something to get excited about!
