|Title:||Quantum phase transition of ground-state entanglement in a Heisenberg spin chain simulated in an NMR quantum computer||Authors:||Peng, X.
|Issue Date:||1-Jan-2005||Citation:||Peng, X., Du, J., Suter, D. (2005-01-01). Quantum phase transition of ground-state entanglement in a Heisenberg spin chain simulated in an NMR quantum computer. Physical Review A - Atomic, Molecular, and Optical Physics 71 (1) : -. ScholarBank@NUS Repository. https://doi.org/10.1103/PhysRevA.71.012307||Abstract:||Using an NMR quantum computer, we experimentally simulate the quantum phase transition of a Heisenberg spin chain. The Hamiltonian is generated by a multiple-pulse sequence, the nuclear-spin system is prepared in its (pseudopure) ground state, and the effective Hamiltonian varied in such a way that the Heisenberg chain is taken from a product state to an entangled state, and finally to a different product state. © 2005 The American Physical Society.||Source Title:||Physical Review A - Atomic, Molecular, and Optical Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/97700||ISSN:||10502947||DOI:||10.1103/PhysRevA.71.012307|
