Reduced coupling with global pulses in quantum registers

Year: 2014

Type: article

Abstract: Decoupling is an important tool used to prolong the coherence time of quantum systems.However, most decoupling schemes have assumed selective controls on the system, and it is believed that with global pulses one can only decouple systems with certain coupling terms like secular dipole-dipole coupling.In this article, we show that with global pulses it is possible to reduce the coupling strength of other types of coupling, which we demonstrate with Ising coupling.The complexity of such pulses is independent of the size of the system.
