"Dr Joseph Cotter takes some unusual pieces of luggage on his trips on the
London underground. They include a stainless steel vacuum chamber, a few
billion atoms of rubidium and an array of lasers that are used to cool his
equipment to a temperature just above absolute zero.
While not the average kit you would expect to find being dragged into carriages
on the District Line, this is the gear that Cotter – who works at Imperial
College London’s Centre for Cold Matter – uses on his underground travels.
Though the baggage may be bizarre, it has an ambitious purpose. It is being
used to develop a quantum compass – an instrument that will exploit the
behaviour of subatomic matter in order to develop devices that can accurately
pinpoint their locations no matter where they are placed, paving the way for
the creation of a new generation of underground and underwater sensors.
The ideal place to test it is the London underground, Cotter and his team have
discovered. “We are developing very precise new sensors using quantum
mechanics, and these are showing great promise in the laboratory,” he told the
Observer last week. “However, they are less accurate in real-life settings.
That is why we are taking our equipment to the London underground. It’s the
perfect place for smoothing out the rough edges and getting our equipment to
work in real life.”"
