Quantum limited measurement of magnetic field gradient with entangled atoms
Quantum limited measurement magnetic field gradient entangled atoms
2016/1/23
We propose a method to detect the amplitude gradient of a microwave field by using a pair of entangled two-component Bose-Einstein condensates. We consider the two spatially separated condensates to b...
Internal Diffusion-Limited Aggregation: Parallel Algorithms and Complexity
Internal diffusion gathered circuit subset the comparator
2014/12/22
The computational complexity of internal diffusion-limited aggregation (DLA) is examined from both a theoretical and a practical point of view. We show that for two or more dimensions, the problem of ...
