An Introduction to Quantum Computation
... researchers have noted that there is a fundamental limit to the number of transistors that may be placed on a chip, at least with our current production methods. For better or worse, computers have become a necessary component of our lives, and the notion of an upper limit on computing power does no ...

Students are told that whenever Alice measures either ~/2 or −~/2, she instantly knows that Bob will obtain the opposite result upon measuring the other particle’s spin along the same direction. Then it is mentioned that the two particles are entang ...

My objective here will be to provide a concise account of the stark essentials of some of my recent work as it relates to that wonderful creation of the youthful Jacobi—the theory of theta functions. I will omit details except when they bear critically upon a point at issue.1 And in the tradition of ...

How Stands Collapse II
... Rather than reprise my previous argument, I wish to take this opportunity to make it more simple and general. My point of view is that a collapse theory is different from standard quantum theory and, as I said to John Bell in Amherst, therefore requires a new language, conceptual as well as terminol ...

Lorentz violating field theories and nonperturbative physics
... At the fundamental (usually Planck scale) level, models with LIV have been put forward in roughly two categories. 1. Models with a Lorentz-invariant Lagrangian (dynamical Lorentz invariance) that exhibit spontaneous symmetry breaking of Lorentz invariance. 2. Models without Lorentz symmetry at the f ...
