Microsoft Edges Closer to Quantum Computer Based on Elusive Particle
Researchers make Majorana fermions, but now must try to control them

At Microsoft Corp.'s Dutch research facility at the Delft University of Technology, several large cylindrical metal tubes hang from the ceiling.
Each tube - a dilution refrigerator used to cool circuits down to temperatures colder than deep space - costs more than $500,000, and has helped Microsoft's researchers create an elusive subatomic particle that the company hopes will serve as the building block of its effort to create commercially-viable quantum computers.
