Geometric Effects and Computation in Spin Networks
Alastair Kay, Marie Ericsson
When initially introduced, a Hamiltonian that realises perfect transfer of a quantum state was found to be analogous to an x-rotation of a large spin. In this paper we extend the a…
Measurement of geometric phase for mixed states using single photon interferometry
Marie Ericsson, Daryl Achilles, Julio T. Barreiro +3
Geometric phase may enable inherently fault-tolerant quantum computation. However, due to potential decoherence effects, it is important to understand how such phases arise for {\i…
A Single Photon Source With Linear Optics and Squeezed States
Casey R. Myers, Marie Ericsson, Raymond Laflamme
Quantum information processing using photons has recently been stimulated by the suggestion to use linear optics, single photon sources and detectors. The recent work by Knill has…
Connections between relative entropy of entanglement and geometric measure of entanglement
Tzu-Chieh Wei, Marie Ericsson, Paul M. Goldbart +1
As two of the most important entanglement measures--the entanglement of formation and the entanglement of distillation--have so far been limited to bipartite settings, the study of…
An experimental observation of geometric phases for mixed states using NMR interferometry
Jiangfeng Du, Ping Zou, Mingjun Shi +6
Examples of geometric phases abound in many areas of physics. They offer both fundamental insights into many physical phenomena and lead to interesting practical implementations. O…
Holonomic quantum logic gates
Marie Ericsson
This is a brief overview of quantum holonomies in the context of quantum computation. We choose an adequate set of quantum logic gates, namely, a phase gate, the Hadamard gate, and…
