The double-padlock problem: is secure classical information transmission possible without key exchange?
James M. Chappell, Derek Abbott
The idealized Kish-Sethuraman (KS) cipher is theoretically known to offer perfect security through a classical information channel. However, realization of the protocol is hitherto…
A probabilistic approach to quantum Bayesian games of incomplete information
Azhar Iqbal, James M. Chappell, Qiang Li +2
A Bayesian game is a game of incomplete information in which the rules of the game are not fully known to all players. We consider the Bayesian game of Battle of Sexes that has sev…
The gravitational field of a cube
James M. Chappell, Mark J. Chappell, Azhar Iqbal +1
Large astronomical objects such as stars or planets, produce approximately spherical shapes due to the large gravitational forces, and if the object is rotating rapidly, it becomes…
Generalized Minkowski spacetime with geometric algebra
James M. Chappell, David L. Berkahn, Derek Abbott
We begin from the generalised eight-dimensional Minkowski spacetime structure, previously developed in Clifford geometric algebra . We propose that this is the corr…
N-player quantum games in an EPR setting
James M. Chappell, Azhar Iqbal, Derek Abbott
The -player quantum game is analyzed in the context of an Einstein-Podolsky-Rosen (EPR) experiment. In this setting, a player's strategies are not unitary transformations as in…
An improved formalism for the Grover search algorithm
James M. Chappell, M. A. Lohe, Lorenz von Smekal +2
The Grover search algorithm is one of the two key algorithms in the field of quantum computing, and hence it is of significant interest to describe it in the most efficient mathema…
