Muon collider feasibility: new studies of a low emittance muon source using positron beam
Donatella Lucchesi, University and INFN of Padova Dmitri Denisov The idea of a muon collider is intriguing physicists because it would give the possibility to explore phenomena in the multi-TeV energy region colliding point-like particles. The study of a muon accelerator with a hadronic muon source, ie muons coming from pion and kaon decays, has been pursued showing limitations due to the broad momentum and angular spectra of the decay muons.

Schrödinger Cats, Maxwell’s Demon and Quantum Error Correction (that works)
Steven Girvin, Yale Quantum Institute Pushpa Bhat A revolution is underway in the construction of ‘artificial atoms’ out of superconducting electrical circuits. These macroscopic ‘atoms’ have quantized energy levels and can emit and absorb quanta of light (in this case microwave photons), just like ordinary atoms. The large size of these ‘atoms’ yields remarkably strong atom-photon coupling and has given us the ability to completely control and measure the quantum state of the electromagnetic field in a cavity at the level of individual microwave photons.

European Particle Physics Strategy
Halina Abramowicz, Tel Aviv University Dmitri Denisov European particle physics community is planning exercise of long term planning. The process is starting with proposals to consider expected late 2018 and discussions to progress in 2019. The final plan is expected to be approved by CERN Council in Spring of 2020. The colloquium will discuss the process and goals of the European strategy exercise and how various groups and individual scientists can participate in this process.

Quantum interference in coupled cavity-qubit systems
David P. Pappas, NIST Alexander Romanenko Quantum networks will enable extraordinary capabilities for communicating and processing quantum information. These networks require a that node that receives two coherent inputs and sends a conditional output to the next cascaded node through a quantum channel. Here, we demonstrate this basic functionality by exploiting a controllable interaction between electromagnetic quanta and discrete levels in... More »

Exploration of the Solar System’s Ocean Worlds
Jonathan Lunine, Cornell University Alexander Romanenko Ocean worlds is the label given to objects in the solar system that host stable, globe-girdling bodies of liquid water—“oceans”—on or beneath their surfaces. The Galileo orbiter at Jupiter and Cassini at Saturn discovered subsurface water oceans on Europa, Enceladus and Titan, and surface methane seas on the last of these. What we know of these bodies of liquid, what are the prospects for life there and how do we explore them are the topics of this talk.
