Input: Consider Input: Question: How many total people have been awarded the fellowship that Heutz received in 2007? Passage:Heutz joined Imperial College London in 2007 as a Royal Society Dorothy Hodgkin Research Fellow. She was awarded the 2008 Institute of Materials, Minerals and Mining Silver Medal for her research on organic thin films. In particular she had developed new electron - donor morphologies for efficient solar cells. Heutz specialises in the use of electron paramagnetic resonance (EPR) to monitor unpaired electrons within materials. She used EPR to monitor spins within copper phthalocyanine solar cells. Whilst working on new materials for photovoltaics, Heutz showed that electrons in copper phthalocyanine (a blue pigment found in a Bank of England £5 note) exist in a superposition of two different spin states. She demonstrated that copper phthalocyanine could be used for quantum computing, where information is stored as qubits as opposed to binary bits.

Input: Consider Input: Question: How many years were there between the death of Charlemagne and the first award of the Charlemagne Prize? Passage:The Charlemagne Prize (; full name originally Internationaler Karlspreis der Stadt Aachen, International Charlemagne Prize of the City of Aachen, since 1988 Internationaler Karlspreis zu Aachen, International Charlemagne Prize of Aachen) is a prize awarded for work done in the service of European unification. It has been awarded annually since 1950 by the German city of Aachen. It commemorates Charlemagne, ruler of the Frankish Empire and founder of what became the Holy Roman Empire, who resided and is buried in Aachen. Traditionally the award is given to the recipient on Ascension Day in a ceremony in the town hall of Aachen. In April 2008, the organisers of the Charlemagne Prize and the European Parliament jointly created a new European Charlemagne Youth Prize, which recognises contributions by young people towards the process of European integration. Patrons of the foundation are King Philippe of Belgium, King Felipe VI of Spain, and Henri, the Grand Duke of Luxembourg.
