Abstract

Abstract: To realize quantum control and quantum computation on a quantum system, its Hamiltonian parameters must be determined first. However, in many cases a quantum system is access-limited. In our experiment, the dynamic evolution of a 3-spin XY chain was simulated with an NMR quantum simulator. The Hamiltonian parameters of the 3-spin XY chain were determined by measuring only the first spin and processing the data obtained.

Key words: indirect determination of Hamiltonian parameters, XY spin chain, quantum simulation
