Quantum estimation of magnetic-field gradient using W-state
H. T. Ng, K. Kim
We study the precision limits of detecting a linear magnetic-field gradient by using W-states in the presence of different types of noises. We consider to use an atomic spin chain…

Particle-hole entanglement of ultracold atoms in an optical lattice
H. T. Ng
We study the ground state of two-component bosonic atoms in a one-dimensional optical lattice. By applying an external field to the atoms at one end of lattice, the atoms are trans…

Quantum-limited measurement of magnetic-field gradient with entangled atoms
H. T. Ng
We propose a method to detect the microwave magnetic-field gradient by using a pair of entangled two-component Bose-Einstein condensates. We consider the two spatially separated co…
