YQIS 6,
Sixth International Conference for Young Quantum Information Scientists

Abstract:  YQIS provides a venue for young researchers (graduate students, post-doctoral researchers, etc.) to share their research and strengthen ties to the quantum information community. YQIS welcomes submissions from all areas of theoretical and experimental quantum information science including: Quantum algorithms, especially for simulating physics. Quantum error correction and fault tolerance. Near-term ("NISQ") algorithms and error mitigation. Quantum Shannon theory. Quantum computing technologies (superconducting qubits, photonics, etc.) Quantum resource theories. Quantum foundations. The quantum information community stands out for its cross-disciplinary nature, bringing together physicists, mathematicians, computer scientists, engineers, and more. YQIS 2021 seeks to provide a platform for early-career researchers to engage in rich, multi-disciplinary discussions and network with future leaders of the field.

A NICER view of neutron stars

Abstract:  NICER, the Neutron Star Interior Composition Explorer, is an X-ray telescope that was installed on the International Space Station in 2017. Its mission is to study the nature of the densest matter in the Universe, found in the cores of neutron stars, by measuring their masses and radii. NICER uses Pulse Profile Modeling, a technique that exploits relativistic effects on X-rays emitted from the hot magnetic polar caps of millisecond pulsars. The technique also lets us map the hot emitting regions, which form as magnetospheric particles slam into the stellar surface. I will present NICER's current results and ongoing analysis and discuss the implications for our understanding of ultradense matter, pulsar emission, and stellar magnetic fields.

Not Normal: The Uncertainty of Scientific Measurements

Abstract:  When scientists report uncertainties, what do they tell us? How excited should we get when a 3 or 4 sigma result suggests new physics? Researchers in fields from Medicine to Physics do a pretty good job of estimating the chance of small errors, but the frequency of big disagreements for even the best-made measurements is orders of magnitude greater than naively expected. Unknown problems appear to have power-law distributions consistent with how complex systems fail and how systematic errors are constrained. Occasional outliers are unavoidable at the research frontier.
