Direct experimental reconstruction of the Bloch sphere
Abstract: The scientific journey from the first hints of quantum behaviour to the Bloch sphere in your textbook was a long and tortuous one. But using some of the technological and conceptual fruits of that journey, we show that an experiment can manifest the Bloch sphere via an analysis that doesn't require ... read more

Single-photon test of Hyper-Complex Quantum Theories
Speaker(s): Lorenzo Procopio
Abstract: One of the most successful theories in physics until now is quantum mechanics. However, the physical origins of its mathematical structure are still under debate, and a "generalized" quantum theory to unify quantum mechanics and gravity is still missing. Recently, in an effort to better understand t... read more

Experimental measurement tradeoffs, from Heisenberg to Aharonov to quantum data compression
Speaker(s): Aephraim Steinberg
Abstract: Tradeoffs in measurement and information are among the central themes of quantum mechanics. I will try to summarize in this talk a few of our experiments related to modern views of these topics. In particular, I will try to give an example or two of the power of "weak measurements," both for funda... read more

Naïve experiments for measuring incompatible observables
Speaker(s): Jeff Lundeen
Abstract: Sets or pairs of incompatible observables, such as momentum and position, play a pivotal role in a wide range of distinctly quantum effects and applications, including quantum cryptography, the Heisenberg Uncertainty Principle, quantum state tomography, and Bell’s inequalities. In particular, in q... read more

Experimental implementation of quantum-coherent mixtures of causal relations
Abstract: Understanding the causal influences that hold among the parts of a system is critical both to explaining that system's natural behaviour and to controlling it through targeted interventions. In a quantum world, understanding causal relations is equally important, but the set of possibilities is far ... read more
