Harry Buhrman

Harry Buhrman is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Harry Buhrman rather than just read about it. In short: Harry Buhrman (born 1966) is a Dutch computer scientist, currently Chief Scientist Quantum Algorithms & Innovation at Quantinuum. He previously was Professor of algorithms, complexity theory, and quantum computing at the University of Amsterdam (UvA), group leader of the Quantum Computing Group at the Centrum Wiskunde & Informatica (CWI), and executive director of QuSoft, the Dutch research center for quantum softwa…

Key takeaways

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

Reference excerpt

Harry Buhrman (born 1966) is a Dutch computer scientist, currently Chief Scientist Quantum Algorithms & Innovation at Quantinuum. He previously was Professor of algorithms, complexity theory, and quantum computing at the University of Amsterdam (UvA), group leader of the Quantum Computing Group at the Centrum Wiskunde & Informatica (CWI), and executive director of QuSoft, the Dutch research center for quantum software. Buhrman research interests are on Quantum Computing, Quantum Information, Quantum Cryptography, Computational complexity theory, Kolmogorov Complexity, and Computational Biology. Buhrman contributed substantially to the quantum analogue of Communication complexity, exhibiting an advantage of the use of qubits in distributed information-processing tasks. Although quantum entanglement cannot be used to replace communication, can be used to reduce the communication exponentially. Buhrman was elected a member of the Royal Netherlands Academy of Arts and Sciences in 2020.

Worked examples

Example 1 — a first encounter with Harry Buhrman

Start with the simplest possible case. Write down what Harry Buhrman claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Harry Buhrman 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 Harry Buhrman 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 Harry Buhrman

In research
Harry Buhrman appears in astronomy 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 Harry Buhrman 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
Harry Buhrman is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1966 births, Academic staff of the University of Amsterdam, Computer scientist stubs, so understanding it makes those chapters shorter.
In everyday life
Look for Harry Buhrman 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.
