Cats wanted dead and alive: quantum technologies | Professor Ben Murdin | TEDxSurreyUniversitySalon

02/01/2015 13:46:58

This talk was given at a local TEDx event, produced independently of the TED Conferences. The idea that objects can be in two places at once, or do two things at once, is alien to most of us but is normal in the atomic world. Erwin Schrodinger, one of the fathers of quantum physics, had a "thought experiment" where he tried to imagine kinds of things that must be possible if the quantum ideas could spill over into the large scale of our every day experience. He imagined a cat connected to an atom via a detector and a bottle of poison. If the atom can in two places at once, it can be detected and not detected, and the poison can be triggered and not triggered, so the cat could be both alive and dead! Schrodinger thought this was absurd, and even thought this might mean the whole idea of quantum physics was crazy. Although noone seems to feel the need to play with cats, bigger and bigger things are being put into the "superposition" state, including, now, silicon chips. The quantum technology age is beginning!

Ben is an experimentalist interested in the study of electronic and optical properties of semiconductors and semiconductor nano structures using high-pressures, magnetic-fields, and linear, nonlinear and time resolved infrared spectroscopy. He likes "applicable physics" rather than really pure or really applied physics.

About TEDx, x independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* *Subject to certain rules and regulations

Wowww
Grasping the next level of use of material like on the old days - developing the transistor and a playing it to electronic logic.
Now using the massively tiniest form of concrete elements to do work not only in one but many states of "matter-being".
It's like looking in many directions at the same time.

Brilliant like a lamp:. Thank you for re-mystifying me...I luv quantum...but yeah...it's here and there, lol;..bit busy isn't it? Kinda like watching a two year old child...lol...leaves ya exhausted at the end of day but ya love every moment:;
