Non-local games, also known as interactive proof systems, have long been an important area of study for mathematicians, physicists and computer scientists. Starting with the famous CHSH game in 1969, it has been known that non-local games are also an ideal area to explore the differences between quantum and classical behaviour. This has motivated the study of the area of non-local games for people working in quantum information.

Heat-Bath Algorithmic Cooling is a technique for producing pure quantum systems by utilizing a surrounding heat-bath. Here we connect the study of these cooling techniques to the resource theory of athermality, enabling us to derive provably optimal cooling protocols under a variety of experimental restrictions on the available control.

Recent progress in creating graphene quantum dots (QDs) with fixed build-in potentials has offered a new platform to visualize and probe the confined electronic states. In this talk, I describe scanning tunneling spectroscopy measurements of the energy spectrum of graphene QDs as a function of energy, spatial position, and magnetic field.

QUANTUM + Film: A screening of 10 Quantum Shorts
A festival for quantum-inspired films
The Quantum Shorts festival called for short films inspired by quantum physics and the universe answered. Filmmakers all over the world responded with their movies.

Superconducting circuits have emerged as a competitive platform for quantum computation, satisfying the challenges of controllability, long coherence and strong interactions. Here we apply this toolbox to the exploration of strongly correlated quantum materials made of microwave photons. We develop a versatile recipe that uses engineered dissipation to stabilize many-body phases, protecting them against intrinsic photon losses.

Microwave optomechanical circuits have been demonstrated in the past years to be powerful tools for both, exploring fundamental physics of macroscopic and massive quantum objects as well as being promising candidates for novel on-chip quantum limited microwave devices. In this work, we explore a microwave optomechanical device consisting of a coplanar microwave cavity coupled to a mechanical high quality factor nanobeam resonator.
Fabrication and Growth of 111 SiNWs for Mechanical Spin-Detection
Pardis Sahafi, Institute for Quantum Computing
In our group, vertical Si nanowires grown on a 111 surface are used for force detection in nanoscale NMR and ESR. These measurements require a very long (20 µm) and minimally tapered vertical Si nanowires, to be used as nano-mechanical oscillators with a high quality factor (Q ~ 104).

This talk reflects on recent research in progress with Andras Gilyen. Over the years, there have been a number of papers dealing with quantum algorithms testing some properties of classical probability distributions. Our goal is to understand what is the right way for quantum algorithms to access the distribution. There is a number of possible models, and we analyse their mutual strength.
