Samuel L. Braunstein

Samuel L. Braunstein is a physics 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 Samuel L. Braunstein rather than just read about it. In short: Samuel Leon Braunstein (born 1961) is a professor at the University of York, England. He is a member of a research group in non-standard computation and has a particular interest in quantum information, quantum computation, and black hole thermodynamics.

Key takeaways

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

Reference excerpt

Samuel Leon Braunstein (born 1961) is a professor at the University of York, England. He is a member of a research group in non-standard computation and has a particular interest in quantum information, quantum computation, and black hole thermodynamics. Braunstein has written or edited three books and has published more than 140 papers, which have been cited over 40,000 times. His most important work is on quantum teleportation, and published in a paper titled Unconditional Quantum Teleportation. The paper has been cited more than 3,000 times and received significant coverage in both the scientific and mainstream press. In February 2006, Braunstein made the news due to his involvement in the first successful demonstration of quantum telecloning. From 2009, he began to research black hole thermodynamics, contributing to the black hole information paradox and the firewall paradox. Braunstein co-authored papers with Gilles Brassard and Simone Severini, with whom he introduced the Braunstein-Ghosh-Severini Entropy of a graph.

Education Braunstein completed his PhD in 1988 at Caltech, under Carlton M. Caves. His dissertation was titled Novel Quantum States and Measurements.

Worked examples

Example 1 — a first encounter with Samuel L. Braunstein

Start with the simplest possible case. Write down what Samuel L. Braunstein 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 Samuel L. Braunstein 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 Samuel L. Braunstein 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 Samuel L. Braunstein

In research: Samuel L. Braunstein 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 Samuel L. Braunstein 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: Samuel L. Braunstein is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1961 births, 21st-century Australian physicists, Computer scientists of the University of York, so understanding it makes those chapters shorter.
In everyday life: Look for Samuel L. Braunstein 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.
