Reference excerpt

Paola Cappellaro is an Italian-American engineer who is a Professor of Nuclear Science and Engineering at the Massachusetts Institute of Technology. Her research considers electron-spin resonance, nuclear magnetic resonance and quantum information processing. She also leads the MIT Quantum Engineering Group at the Center for Ultracold Atoms and is Principal Investigator at the Research Laboratory of Electronics.

Early life and education Cappellaro was born in Italy, where she attended the Polytechnic University of Milan, majoring in nuclear engineering. She was part of a joint Master's program with the École Centrale Paris, and graduated in 2000. Cappellaro moved to the United States for her graduate studies, where she worked alongside David G. Cory on quantum computation. In 2006, Cappellaro earned her doctorate at the Massachusetts Institute of Technology (MIT). Her doctorate considered quantum state transfer in spin chains, making use of magnetic-based approaches to understand and explore spin transfer dynamics. She completed her postdoctoral training at the Institute for Theoretical Atomic, Molecular and Optical Physics, Harvard University.

Research and career In 2009, Cappellaro returned to the Massachusetts Institute of Technology, where she was made an Assistant Professor. She serves as Head of the MIT Quantum Engineering Group at the Center for Ultracold Atoms. Cappellaro has developed novel control techniques for electronic and nuclear spin qubits. She realized the first nitrogen-vacancy center diamond-based magnetometers. She pioneered the use of nuclear magnetic resonance to understand the propagation of spin excitations along a chain of interacting spins. In 2020, Cappellaro demonstrated that it is possible to make use of the nitrogen-vacancy (NV) qubits in diamond to perform quantum operations. These NVs are defects which can be manipulated by electromagnetic waves and respond by emitting light that can carry quantum information. These NV centers are usually surrounded by other 'spin' defects, which have unknown spin properties. When an NV qubit interacts with a spin defect, it loses its coherent state and can no longer perform quantum operations. As NV qubits can be identified and controlled using microwave pulses, they can be used to probe their nearby environments. Subsequent microwave pulses and applied magnetic fields can resonantly excite nearby spin defects, ultimately revealing their location. Cappellaro showed that these defects can then be leveraged as additional qubits, which can be briefly entangled with one another to achieve a coherent quantum state. These manifest as spikes in the resonance spectra. Cappellaro measured the spins of these defects using electron-spin resonance. Cappellaro is the Ford Professor of Engineering, Professor of Nuclear Science and Engineering and Professor of Physics at MIT.

Worked examples

Example 1 — a first encounter with Paola Cappellaro

Start with the simplest possible case. Write down what Paola Cappellaro 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 Paola Cappellaro 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 Paola Cappellaro 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 Paola Cappellaro

In research: Paola Cappellaro 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 Paola Cappellaro 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: Paola Cappellaro is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century American women, American women academics, American women scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Paola Cappellaro 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.
