サリー大学教員が名誉あるリサーチアワードを受賞

2012年10月16日

サリー大学のベン・マーディン教授は本日10月16日、シリコンチップの中に捉えられた原子を用いた量子計算の研究で、名誉あるRoyal Society Wolfson Research Merit Awardを受賞しました。教授の研究は、最新のノーベル物理学賞を受賞した研究とも深く結びついた内容とのことです。

Professor Ben Murdin of the University of Surrey was today (16 October) awarded a prestigious Royal Society Wolfson Research Merit Award for his research on quantum computing with atoms encased inside a silicon chip.  This work is closely related to the latest Nobel prize for physics – the laureates Haroche and Wineland pioneered quantum computing in atoms and ions suspended in empty vacuum. They developed techniques for putting each atom into a state of oscillating at two different frequencies at once, like a chord on a guitar string.

Erwin Schrodinger, one of the fathers of quantum physics speculated that this weird behaviour might eventually enable construction of a machine that could one day be capable of making a large every-day object do two jobs at once.  Schrodinger’s thought-experiment involved making a cat be simultaneously alive and dead, but most researchers are instead trying to harness this ability to make more powerful computers.  The problem is that the effect of surroundings is to disturb the delicate dual existence and cause the object to choose one state or the other, which is why successful experiments tend to be on very small objects in empty space. Using very similar optical techniques to Haroche and Wineland, Professor Murdin and his team succeeded in putting phosphorus atoms into chord-like states that are simultaneously oscillating and not oscillating at the same time.

Professor Murdin comments: “The shocking thing for us was that the surrounding silicon did not disturb the delicate chord-like state of the phosphorus atoms much. The phosphorus atom is almost as big as a transistor in an ordinary silicon computer chip, so it is in contact with about a million other electrons from the silicon. When we started we thought that this would mean the weird wave-like motion of the phosphorus would instantly collapse giving us back the ordinary one-place-at-a-time particle motion. It turns out that there is plenty of time to do a computer operation, and we are now working on trying to replicate this with a single phosphorus atom rather than a big bunch of them.”
