Aethereal Gravity
Speaker(s): Brendan Foster
Abstract: Hints from quantum gravity suggest that a preferred frame may actually exist. One way to accommodate such a frame in general relativity without sacrificing diffeomorphism invariance is to couple the metric to a dynamical, time like, unit-norm vector field--the "aether". I will discuss properties an... read more

Probability in the Everett interpretation: How to live without uncertainty
Speaker(s): Hilary Greaves
Abstract: The Everett (many-worlds) interpretation has made great progress over the past 20-30 years, largely due to the role of decoherence in providing a solution to the preferred basis problem. This makes it a serious candidate for a realist solution to the measurement problem. A remaining objection to the... read more

Ancillae with Homogeneous Errors
Speaker(s): Bryan Eastin
Abstract: Ancillary state construction is a necessary component of quantum computing. Ancillae are required both for error correction and for performing universal computation in a fault-tolerant way. Computation to an arbitrary accuracy, however, is effectively achieved by increasing the number of qubits i... read more

The Distinguishability of Random Quantum States
Speaker(s): Ashley Montanaro
Abstract: It is a fundamental property of quantum mechanics that non-orthogonal pure states cannot be distinguished with certainty, which leads to the following problem: Given a state picked at random from some ensemble, what is the maximum probability of success of determining which state we actually have? I... read more

Additivity Conjectures in Quantum Information Theory
Speaker(s): Motohisa Fukuda
Abstract: Quantum information theory has two equivalent mathematical conjectures concerning quantum channels, which are also equivalent to other important conjectures concerning the entanglement. In this talk I explain these conjectures and introduce recent results.

A Bell inequality Analogue in quantum measure theory
Speaker(s): Joe Henson
Abstract: In stochastic treatments of the ERRB set-up, it is equivalent to impose Bell's inequalities, a local causality condition, or a certain "non-contextual hidden variables" condition. But these conditions are violated by quantum mechanics. On the other hand, it is possible to view quantum mechanics as... read more

Reliable Quantum State Estimation from Quantum Scoring Rules
Speaker(s): Robin Blume-Kohout
Abstract: Inferring a quantum system's state, from repeated measurements, is critical for verifying theories and designing quantum hardware. It's also surprisingly easy to do wrong, as illustrated by maximum likelihood estimation (MLE), the current state of the art. I'll explain why MLE yields unreliable an... read more
