Mapping all classical spin models to a lattice gauge theory
G. De las Cuevas, W. Dür, H. J. Briegel +1
In our recent work [Phys. Rev. Lett. 102, 230502 (2009)] we showed that the partition function of all classical spin models, including all discrete standard statistical models and…
Measurement-based quantum computation
H. J. Briegel, D. E. Browne, W. Dür +2
Quantum computation offers a promising new kind of information processing, where the non-classical features of quantum mechanics can be harnessed and exploited. A number of models…
Concatenated tensor network states
R. Hübener, V. Nebendahl, W. Dür
We introduce the concept of concatenated tensor networks to efficiently describe quantum states. We show that the corresponding concatenated tensor network states can efficiently d…
Universal resources for approximate and stochastic measurement-based quantum computation
C. E. Mora, M. Piani, A. Miyake +3
We investigate which quantum states can serve as universal resources for approximate and stochastic measurement-based quantum computation, in the sense that any quantum state can b…
