Probability in many-worlds theories
Anthony J. Short
We consider how to define a natural probability distribution over worlds within a simple class of deterministic many-worlds theories. This can help us understand the typical proper…
Eigenstate Thermalisation on Average
Joe Dunlop, Oliver Cohen, Anthony J. Short
We consider conditions under which an isolated quantum system approaches a microcanonical equilibrium state. A key component is the eigenstate thermalisation hypothesis, which prop…
Quantum theory cannot violate a causal inequality
Tom Purves, Anthony J. Short
Within quantum theory, we can create superpositions of different causal orders of events, and observe interference between them. This raises the question of whether quantum theory…
Channels, measurements and post-selection in quantum thermodynamics
Tom Purves, Tony Short
We analyse the benefit, in terms of extracting work, of having a single use of a quantum channel or measurement in quantum thermodynamics. This highlights a connection between unit…
Local Probability Conservation in Discrete Time Quantum Walks
Samuel T. Mister, Benjamin J. Arayathel, Anthony J. Short
We show that probability is locally conserved in discrete time quantum walks, corresponding to a particle evolving in discrete space and time. In particular, for a spatial structur…
Reference frames which separately store non-commuting conserved quantities
Sandu Popescu, Ana Belén Sainz, Anthony J. Short +1
Even in the presence of conservation laws, one can perform arbitrary transformations on a system if given access to a suitable reference frame, since conserved quantities may be ex…
