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).

Alexander Belovs, University of Latvia

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.

Giovanni Fanchini, Western University

In this talk, we will review the use of thin films of organic polyradicals – organic polymers with one unpaired electron per monomer [1] – for memory devices and other applications. Although memory devices based on radical polymers have been often proposed, their stability was frequently limited to a few writing cycles, despite the excellent quality of the active layer.
