玻色原子光晶格中纠缠态的集体测量

Entanglement Detection in Optical Lattices of Bosonic Atoms with Collective Measurements

Geza Toth

摘要:

纠缠检测的最低要求进行了讨论的自旋链中的自旋不能单独访问。所提出的方法可以探测到接近于团簇态和多体单重态的纠缠态,并且在两态玻色原子光晶格中的实验实现是可行的。纠缠的标准是基于纠缠证人和集体观测的不确定性。

英文摘要:

The minimum requirements for entanglement detection are discussed for a spin chain in which the spins cannot be individually accessed. The methods presented detect entangled states close to a cluster state and a many-body singlet state, and seem to be viable for experimental realization in optical lattices of two-state bosonic atoms. The entanglement criteria are based on entanglement witnesses and on the uncertainty of collective observables.
