In that sense it is save to say that I owe all my current experimental knowhow to the people of QDev. One man stands out, Charlie Marcus. He offered me the chance to be a part of his new ...

Quantum Expanders: Motivation and Constructions
... Their quantum expander is based on a Cayley expander over the Abelian group Zn2 . The main drawback of Cayley graphs over Abelian groups is that [26, 4] showed that such an approach cannot yield constant degree expanders. Indeed, this is reflected in the log2 N term in Theorem 1.3. There are constan ...

Introduction to the Bethe Ansatz II
... At h 6= 0, all of these levels experience a downward shift of magnitude hSTz . All spacings between adjacent levels shrink by the same amount h. The first level crossing occurs between the state |Ai with STz = 0 and the state with STz = 1, which thereby becomes the new ground state. Next, this state ...
