Physicists at the University of Oxford, UK have set a new world record for accurately controlling a single quantum bit as part of global scientific efforts to create useful quantum computers. The new level of accuracy is nearly 7 times greater than the previous record (achieved by the same team in 2014) and is reported in the Physical Review Lette…

Sharper than lightning: Oxford’s one-in-6. 7-million quantum breakthrough

Physicists at the University of Oxford have set a new global benchmark for the accuracy of controlling a single quantum bit, achieving the lowest-ever error rate for a quantum logic operation--just 0.000015%, or one error in 6.7 million operations. This record-breaking result represents nearly an order of magnitude improvement over the previous benchmark, set by the same research group a decade ago.

New Quantum Algorithm Factors Numbers With One Qubit

Quantum computers still can’t do much. Almost every time researchers have found something the high-tech machines should one day excel at, a classical algorithm comes along that can do it just as well on a regular computer. One notable exception? Taking apart numbers. In 1994, the mathematician Peter Shor devised an algorithm that would let quantum computers factor big numbers exponentially faster… Source

Oxford University Demonstrates Record-Low Single-Qubit Gate Error Using Microwave-Controlled Calcium Ions - Quantum Computing Report

Researchers at the University of Oxford have reported a new benchmark for single-qubit gate fidelity using trapped-ion technology, achieving an error rate of just 0.000015%—equivalent to one error in 6.7 million operations. The result is scheduled for publication in Physical Review Letters and represents an order-of-magnitude improvement over the group’s own prior record set in [...] The post Oxford University Demonstrates Record-Low Single-Qubi…
