Quantum Memory in Atomic Ensembles - Oxford Physics
... Thanks to my Oxford massif, Andy Scott and Tom Rowlands-Rees, who know a good lunch when they see one. And in that vein, thanks to Matthijs Branderhorst, who along with Ben, introduced me to the burrito. There is a growing ultrafast diaspora — good people in far-off places — and of these I should li ...

In the fourth chapter, we present good families of low-density paritycheck error-correcting codes derived from Platonic Surfaces and in the fifth chapter, from Ramanujan Surfaces. For both families, we prove ...

Towards the mathematics of quantum field theory
... The notion of field is very general. From the mathematician’s viewpoint, it means a function x : M −→ C between two spaces, that represents the motion of a physical object in a configuration space C, with parameter space M . The notion of space must be taken here in a widely generalized sense, becau ...

NUCLEAR MAGNETIC RESONANCE QUANTUM COMPUTATION
... NMR signal detection is best described using a classical view [8]. The ensemble average of the spins behaves like a classical magnetisation rotating at the Larmor frequency, and the NMR detector is a coil of wire wrapped around the sample. As the magnetisation cuts across the wires it induces an EMF ...
