Quantum Computer Building Block is 200 Times Faster | NextBigFuture.com

University of New South Wales (UNSW) Professor Michelle Simmons and her team have developed the fastest two-qubit gate between atoms suspended in silicon. A two-qubit gate is the central building block of any quantum computer – and the UNSW team’s version of it is the fastest that’s ever been demonstrated in silicon, completing an operation in 0.8 nanoseconds, which is ~200 times faster than other existing silicon spin-based two-qubit gates. The next major goal is building a 10-qubit quantum integrated circuit which they target within 3-4 years. Nature – A two-qubit gate between phosphorus donor electrons in silicon Using a
