The problem of equilibration and the computation of correlation functions on a quantum computer
, 1999 We address the question of how a quantum computer can be used to simulate experiments on quantum systems in thermal equilibrium. We present two approaches for the preparation of the equilibrium state on a quantum computer.

Quantum Computation as Geometry [PDF]
Science, 2006 Quantum computers hold great promise for solving interesting computational problems, but it remains a challenge to find efficient quantum circuits that can perform these complicated tasks. Here we show that finding optimal quantum circuits is essentially equivalent to finding the shortest path between two points in a certain curved geometry.

Unconventional Quantum Computing Devices [PDF]
in `Unconventional Models of Computation,' C.S. Calude, J. Casti,
M.J. Dinneen, eds., Springer, Singapore, 1998, 2000 This paper investigates a variety of unconventional quantum computation devices, including fermionic quantum computers and computers that exploit nonlinear quantum mechanics. It is shown that unconventional quantum computing devices can in principle compute some quantities more rapidly than `conventional' quantum computers.

ALD‐Assisted VO2 for Memristor Application
Advanced Engineering Materials, EarlyView.This work demonstrates a strategy for depositing VOx using thermal atomic layer deposition (ALD) followed by thermal annealing to synthesize VO2. The thin film and core/shell wire memristors exhibit excellent switching performance and are highly sensitive to ambient temperature.

Geometrical perspective on quantum states and quantum computation [PDF]
arXiv, 2013 We interpret quantum computing as a geometric evolution process by reformulating finite quantum systems via Connes' noncommutative geometry. In this formulation, quantum states are represented as noncommutative connections, while gauge transformations on the connections play a role of unitary quantum operations. Thereby, a geometrical model for quantum
