Picturing qubits in phase space
Focusing particularly on one-qubit and two-qubit systems, I explain how the quantum state of a system of n qubits can be expressed as a real function—a generalized Wigner function—on a discrete 2 × 2 phase space. The phase space is based on the finite field having 2 elements, and its geometric structure leads naturally to the construction of a complete set of 2 + 1 mutually conjugate bases. PAC...
متن کاملPicturing Pacific Prehistory
This thesis examines similarities and differences between rock-art sites in Vanuatu and the broader western Pacific region, and situates the results within the framework of Pacific prehistory. Prior to this thesis, regional models of rock-art in the western Pacific were founded on corresponding distributions of non-motif variables, such as technical classes (painting or engraving), topographic ...
متن کاملPicturing Indefinite Causal Structure
Following on from the notion of (first-order) causality, which generalises the notion of being tracepreserving from CP-maps to abstract processes, we give a characterization for the most general kind of map which sends causal processes to causal processes. These new, second-order causal processes enable us to treat the input processes as ‘local laboratories’ whose causal ordering needs not be f...
متن کاملMRI Slice Picturing
We set up two coordinate systems, one in the object space and the other on the computer screen. We introduce six parameters to describe the slice plane, and we formulate the coordinate mapping from the screen to the object space. We designed six alternative algorithms that use the given data to estimate the density at any location in space and produce a slice of a three-dimensional array. Some ...
متن کاملPicturing peripheral acuity.
The grain of the retina becomes progressively coarser from the fovea to the periphery. This is caused by the decreasing number of retinal receptive fields and decreasing amount of cortex devoted to each degree of visual field (= cortical magnification factor) as one goes into the periphery. We simulate this with a picture that is progressively blurred towards its edges; when strictly fixated at...
