  • Two debugging aids for developers of applications and systems software on PDP-11 series computers are described. Both debuggers are extensions of Digital Equipment Corporation's ODT (Octal Debugging Technique), and are based on an undocumented, unsupported debugger obtained through DEC. The intent of this paper is to describe these debuggers in a functional sense, discuss the modifications made at LLL to enhance the operation of these debuggers, and to serve as a user's manual for persons developing PDP-11 software.
  • Topological quantum computation (TQC) has emerged as one of the most promising approaches to quantum computation. Under this approach, the topological properties of a non-Abelian quantum system, which are insensitive to local perturbations, are utilized to process and transport quantum information. The encoded information can be protected and rendered immune from nearly all environmental decoherence processes without additional error-correction. It is believed that the low energy excitations of the so-called =5/2 fractional quantum Hall (FQH) state may obey non-Abelian statistics. Our goal is to explore this novel FQH state and to understand and create a scientific foundation of this quantummore » matter state for the emerging TQC technology. We present in this report the results from a coherent study that focused on obtaining a knowledge base of the physics that underpins TQC. We first present the results of bulk transport properties, including the nature of disorder on the 5/2 state and spin transitions in the second Landau level. We then describe the development and application of edge tunneling techniques to quantify and understand the quasiparticle physics of the 5/2 state.« less
  • Two simple methods are presented for the computation of the density matrix of a localized quantum particle. One method is based on a local harmonic approximation and the other on a variational method, which assumes that the density matrix retains a Gaussian functional form as the temperature is decreased.
  • This report presents a selective compilation of basic facts from the fields of particle entanglement and quantum information processing prepared for those non-experts in these fields that may have interest in an area of physics showing counterintuitive, ''spooky'' (Einstein's words) behavior. In fact, quantum information processing could, in the near future, provide a new technology to sustain the benefits to the U.S. economy due to advanced computer technology.
