Metaphysics and mathematics: Perspectives on reality

open access: yesHTS Teologiese Studies/Theological Studies, 2017
The essence of number was regarded by the ancient Greeks as the root cause of the existence of the universe, but it was only towards the end of the 19th century that mathematicians initiated an in-depth study of the nature of numbers.

Complete 3-Qubit Grover search on a programmable quantum computer

open access: yesNature Communications, 2017
Grover’s algorithm provides a quantum speedup when searching through an unsorted database. Here, the authors perform it on 3 qubits using trapped ions, demonstrating two methods for marking the correct result in the algorithm’s oracle and providing data ...

Many Worlds, the Cluster-state Quantum Computer, and the Problem of the Preferred Basis [PDF]

open access: yes, 2011
I argue that the many worlds explanation of quantum computation is not licensed by, and in fact is conceptually inferior to, the many worlds interpretation of quantum mechanics from which it is derived. I argue that the many worlds explanation of quantum
