Simulation of Many-Body Hamiltonians using Perturbation Theory with Bounded-Strength Interactions
Sergey Bravyi, David P. DiVincenzo, Daniel Loss +1
We show how to map a given n-qubit target Hamiltonian with bounded-strength k-body interactions onto a simulator Hamiltonian with two-body interactions, such that the ground-state…
A Kapitza-Dirac-Talbot-Lau interferometer for highly polarizable molecules
Stefan Gerlich, Lucia Hackermueller, Klaus Hornberger +8
Research on matter waves is a thriving field of quantum physics and has recently stimulated many investigations with electrons, neutrons, atoms, Bose-condensed ensembles, cold clus…
Dynamic method to distinguish between left- and right-handed chiral molecules
Yong Li, C. Bruder
We study quantum systems with broken symmetry that can be modelled as cyclic three-level atoms with coexisting one- and two-photon transitions. They can be selectively optically ex…
Generalized Stern-Gerlach Effect for Chiral Molecules
Yong Li, C. Bruder, C. P. Sun
The Stern-Gerlach effect is well-known as spin-dependent splitting of a beam of atoms with magnetic moments by a magnetic-field gradient. Here, we show that an induced gauge potent…
Highly Entangled Ground States in Tripartite Qubit Systems
Beat Röthlisberger, Jörg Lehmann, D. S. Saraga +2
We investigate the creation of highly entangled ground states in a system of three exchange-coupled qubits arranged in a ring geometry. Suitable magnetic field configurations yield…
Entanglement in SU(2)-invariant quantum systems: The positive partial transpose criterion and others
John Schliemann
We study entanglement in mixed bipartite quantum states which are invariant under simultaneous SU(2) transformations in both subsystems. Previous results on the behavior of such st…
