Silicon (Si) CMOS spin qubits have become a promising platform for a future quantum information processor due to recent demonstrations of high fidelity single and two qubit gates [Veldhorst et. al., Nature 526.7573 (2015)], compatibility with industrial CMOS process and promising prospects for scalability.
Since its discovery in 1994, the unconventional superconductivity in Sr2RuO4 has attracted tremendous interest. The prospect of it being a topological chiral p-wave superconductor, which supports Majorana fermions, makes it a potential solid state platform for topological quantum computation. However, despite the multiple signatures in support of chiral p-wave pairing, a number of key measurements in the last decade have called into question this interpretation.

Cooling atomic gases to quantum degeneracy opened the new field of quantum simulation. Here the precise tools of atomic physics can be used to study exotic models from condensed matter or nuclear physics with unique tunability and control. Ultracold molecules bring many new possibilities to quantum simulation. I will review the physics of ultracold molecules, including our recent production of stable, ultracold triplet molecules and what they can add to quantum simulation.
In superconducting quantum circuits the Josephson junction is the key element because it is the only strongly nonlinear and dissipationless circuit element we know. Usually it is used in the superconducting state where it acts as a nonlinear inductor, for example in Josephson qubits or Josephson parametric amplifiers. But a Josephson junction can also be nonlinear and dissipationless when a non-zero DC voltage below the gap is applied.
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.
