Key takeaways

Julia Kempe belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Julia Kempe to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Julia Kempe from memory before moving on to harder problems.

Reference excerpt

Julia Kempe is a French, German, and Israeli researcher in quantum computing. She is currently the Director of the New York University Center for Data Science and Professor at the Courant Institute.

Education and career Kempe was born in East Berlin, to a family of Russian descent. She moved to Austria in 1990, and did her undergraduate studies in mathematics and physics at the University of Vienna from 1992 to 1995, with a year as an exchange student in physics at the University of Technology Sydney. She then earned two Master of Advanced Studies (DEA) degrees in France: one in mathematics in 1996 from Pierre and Marie Curie University and another in 1997 in physics from the École normale supérieure. She completed two doctorates in 2001. The dissertation for her Ph.D. in computer science from the École nationale supérieure des télécommunications was entitled Quantum Computing: Random Walks and Entanglement, and was supervised by Gérard Cohen. Her second Ph.D., in mathematics, was from the University of California, Berkeley, with a dissertation entitled Universal Noiseless Quantum Computation: Theory and Applications and was jointly supervised by Elwyn Berlekamp and chemist K. Birgitta Whaley. She joined CNRS at the University of Paris-Sud in 2001 (overlapping with postdoctoral studies at Berkeley and the Berkeley Mathematical Sciences Research Institute), joined the Tel Aviv University faculty in 2007, and moved her CNRS position from Paris-Sud to Paris Diderot in 2010.. Between 2011 and 2018 she was a researcher in finance. She became director of the Center of Data Science at NYU and a professor at the Courant Institute in September 2018.

Awards and honors In 2006, Kempe won the bronze medal of CNRS and the Irène Joliot-Curie Prize of the French government. In 2009 she won the Krill Prize of the Wolf Foundation, and in 2010 she won the Trophée des femmes en or (English: "Women in Gold" trophy ) for her research. In 1998 she received a reward from Studienstiftung des Deutschen Volkes (English: "German Academic Scholarship Foundation") which was awarded to only 0.25% of students at the time.[10] She became a knight in the National Order of Merit in 2010. In 2018, she was elected to the Academia Europaea.

Worked examples

Example 1 — a first encounter with Julia Kempe

Start with the simplest possible case. Write down what Julia Kempe claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Julia Kempe before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Julia Kempe ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Julia Kempe

In research: Julia Kempe appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Julia Kempe in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Julia Kempe is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century French mathematicians, 21st-century French physicists, 21st-century French women mathematicians, so understanding it makes those chapters shorter.
In everyday life: Look for Julia Kempe outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
