Microsoft Retracts Quantum Computing Paper

This seems to indicate the scientific method system is working. But don't retraction alerts get far less attention than the original paper?   I do note that Wired has following this closely, from the original claims, the objects, and now the withdrawal.  Good.  See in particular their simplified look at quantum computing.

Microsoft-Led Team Retracts Disputed Quantum-Computing Paper  By Tom Simonite in Wired

The 2018 report in Nature claimed to have found evidence of an elusive subatomic particle. A review found that the group had omitted key data. 

A MICROSOFT-LED TEAM of physicists has retracted a high-profile 2018 paper that the company touted as a key breakthrough in the creation of a practical quantum computer, a device that promises vast new computing power by tapping quantum mechanics.

The retracted paper came from a lab headed by Microsoft physicist Leo Kouwenhoven at Delft University of Technology in the Netherlands. It claimed to have found evidence of Majorana particles, long-theorized but never conclusively detected. The elusive entities are at the heart of Microsoft’s approach to quantum computing hardware, which lags behind that of others such as IBM and Google. ... "
