Extending the Promise of the Deutsch--Jozsa--Hoyer Algorithm for Finite Groups
Michael Batty, Samuel L. Braunstein, Andrew J. Duncan
Hoyer has given a generalisation of the Deutsch--Jozsa algorithm which uses the Fourier transform on a group G which is (in general) non-Abelian. His algorithm distinguishes betwee…
Relativistic quantum communication with bosonic and fermionic interferometers
Pieter Kok, Samuel L. Braunstein
We derive the relativistic transformation laws for the annihilation operators of the scalar field, the massive spin-1 vector field, the electromagnetic field and the spinor field.…
Quantum Metrology: Detection of weak forces using Schrodinger Cat resources
Kae Nemoto, W. J. Munro, G. J. Milburn +1
We investigate the utility of non classical states of simple harmonic oscillators (a superposition of coherent states) for sensitive force detection. We find that like squeezed sta…
Quantum algorithms in group theory
Michael Batty, Samuel L. Braunstein, Andrew J. Duncan +1
We present a survey of quantum algorithms, primarily for an intended audience of pure mathematicians. We place an emphasis on algorithms involving group theory.
Quantum mechanical Universal constructor
Arun K. Pati, Samuel L. Braunstein
Arbitrary quantum states cannot be copied. In fact, to make a copy we must provide complete information about the system. However, can a quantum system self-replicate? This is not…
The Partition Ensemble Fallacy Fallacy
Kae Nemoto, Samuel L. Braunstein
The Partition Ensemble Fallacy was recently applied to claim no quantum coherence exists in coherent states produced by lasers. We show that this claim relies on an untestable beli…
