Barbara Terhal coined the term Entanglement Witness for the detection of quantum entanglement. Together with co-authors at IBM and elsewhere she has invented the notions of unextendible product bases, remote state preparation, quantum data hiding and the locking of classical information in quantum states. She has inititiated the versatile use of perturbative gadgets for quantum simulation and quantum complexity theory. With DiVincenzo she has explored the computational power of weaker models of quantum computation such as fermionic linear optics and constant depth circuits. With Bravyi she has proved no-go results on 2D self-correcting quantum memories and proved results on the computational power of sign-free 'stoquastic' Hamiltonians. She has revived an asychronous model of quantum computation due to Margolus as the space-time circuit-to-Hamiltonian construction for use in Hamiltonian and adiabatic computation.
