Proposals for quantum information processing often require the development of new quantum tech- nologies. However, here we build quantum memory by ultracold atoms in one-dimensional optical lattices with existing state-of-the-art technology. Under a parabolic external field, we demonstrate that an arbitrary initial state at an end of the optical lattices can time-evolve and revive, with very high fidelity, at predictable discrete time intervals. Physically, the parabolic field, can catalyze a…

Adiabatic speedup in cutting a spin chain via zero-area pulse control
The adiabatic quantum information processing task requires that the evolution of a system must be kept in its instantaneous eigenstate. However, normally the adiabaticity will be ruined due to the
One-Dimensional Matter Waves as a Multi-State Bit
We design a simple technique to control the position of a localized matter wave. Our system is composed of two counter-phased periodic potentials and a third optical lattice, which can be either
Controlled state transfer in a Heisenberg spin chain by periodic drives
TLDR
The proposed scheme for conditional state transfer in a Heisenberg XXZ spin chain paves the way for the realization of integrated quantum logic elements, and may find application in quantum information processing.
Quantum state transfer through a spin chain in two non-Markovian baths
TLDR
The investigation takes one step toward practical quantum communication through a spin system where the two ends of the spin chain are independently immersed in two bosonic baths using the quantum state diffusion (QSD) equation approach.
Almost-exact state transfer by leakage-elimination-operator control in a non-Markovian environment
We investigate the feasibility of using an effective pulse control method to realize an almost exact state transmission through a uniform chain where the communication channel is immersed in a
Almost exact state transfer in a spin chain via pulse control
Quantum communication through spin chains has been extensively investigated. In this scenario, state transfer through linearly arranged spins connected by uniform nearest-neighbor couplings qualifies
