Barbara M. Terhal (born 1969) is a theoretical physicist working in quantum information and quantum computing. She is a professor in the Delft Institute of Applied Mathematics at TU Delft, as well as leading the Terhal Group at QuTech, the Dutch institute for quantum computing and quantum internet, founded by TU Delft and the Netherlands Organisation for Applied Scientific Research (TNO). Her research concerns many areas in quantum information theory, including entanglement detection, quantum error correction, fault-tolerant quantum computing and quantum memories.

Education and early life

Barbara Terhal was born in Leiden in 1969.[2] Already in her early school days, she enjoyed mathematics, physics and solving puzzles.[3]

Terhal completed her PhD Cum Laude on "Quantum Algorithms and Quantum Entanglement"[4] at the University of Amsterdam in 1999, making her the first person to receive a PhD in quantum computing in the Netherlands.[5] As part of her thesis, she coined the term entanglement witness[6] and proposed their use as alternatives to Bell tests for entanglement detection.

Career and research

After her PhD, Terhal joined the IBM Watson Research Centre in Yorktown Heights, New York[7] and the California Institute of Technology (Caltech) as a postdoctoral researcher. Between 2001 and 2010, she worked at IBM on a number of topics, including low-depth quantum circuits or stoquastic Hamiltonians, perturbative gadgets for quantum simulation and quantum complexity theory. She also developed quantum protocols for remote state preparation, quantum locking and quantum data hiding.

In 2010, Terhal became a professor in theoretical physics at RWTH Aachen University. In addition, she held another position at the Forschungszentrum Jülich from 2015 - 2022.[8] In 2017 she moved to Delft, becoming a professor at the Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) at TU Delft and group leader at QuTech.

Since 2007, Terhal has been a fellow of the American Physical Society and has held the post of Distinguished Visiting Research Chair at the Perimeter Institute in Waterloo, Canada, since 2014.[9]

Terhal's current research focuses on quantum error correction and its realisation in solid-state qubits. She is also interested in quantum complexity theory and how it can be used to demonstrate the power of a quantum computer.
