Barbara M. Terhal (born 1969) is a theoretical physicist working in quantum information and quantum computing. She is a researcher at the Forschungszentrum Jülich (Jülich Research Center),[2] a Professor in the EEMCS Department at TU Delft, as well as the Research Lead for the Terhal Group at QUTech.[3] 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, 1969.[4] Already in her early school days, she enjoyed mathematics, physics and solving puzzles.[5]

Terhal completed her PhD Cum Laude on "Quantum Algorithms and Quantum Entanglement"[6] at the University of Amsterdam in 1999, making her the first person to receive a PhD in quantum computing in the Netherlands.[3] As part of her thesis, she coined the term entanglement witness[6][7] 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[8] 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.[3]

In 2010, Terhal became a professor in theoretical physics at RWTH Aachen University. In addition, she holds another position at the Forschungszentrum Jülich since 2015.

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] She is also a professor at QuTech in Delft since 2017.[8]

Terhal's current research focuses on quantum error correction and its realisation in solid-state qubits.[5] She is also interested in quantum complexity theory and how it can be used to demonstrate the power of a quantum computer.[5]

Awards[]

Barbara Terhal has received the following awards:

  • Awarded the Outstanding Innovation Award by IBM Research in 2007[10]
  • Elected a Distinguished Visiting Research Chair at Perimeter Institute, Waterloo, Canada in 2014[10]
  • Selected as Outstanding Referee by the American Physical Society in 2015[11]
  • Elected member of the Royal Netherlands Academy of Arts and Sciences in 2020.[12]

Her publications include:

  • B.M. Terhal, “Bell Inequalities and The Separability Criterion”, Physics Letters A 271, 319 (2000)[13]
  • B.M. Terhal and D.P. DiVincenzo, “Adaptive quantum computation, constant depth quantum circuits, and Arthur Merlin games”, Quant. Inf. and Comp. 4:2, pp. 134–145 (2004)[14]
  • B.M. Terhal, “Quantum Error Correction for Quantum Memories”, Rev. Mod. Phys. 87, 307 (2015)[15]

She has also written an essay on the fragility of quantum information.[16]
