Big Ideas for Little Minds

Chris Ferrie will take you through a historical journey of his own coming of age with digital software and what that experience has granted him. The lesson to be learned is that children will take advantage of the opportunities they are given, but only if their parents and teachers show genuine interest in the activities giving rise to those opportunities. 20 years from now, there will be a Quantum Technology equivalent of Bill Gates. That future leader is only a young child today.

 Cooling close to absolute zero temperature: a recipe for discoveries

Understanding the interplay of non-equilibrium effects, dissipation and many body interactions is a fundamental challenge in condensed matter physics. In this work, as a case study, we focus on the transient dynamics and the steady state characteristics of the double-dot Aharonov-Bohm (AB) interferometer subjected to a voltage and/or temperature bias. We first consider an exactly solvable case, the noninteracting double-dot AB interferometer.

The properties of ultracold atoms can be profoundly modified with the help of laser beams. They can modify the wavefunction of neutral atoms in such a way that they show behavior of charged particles, e.g. electrons in high magnetic fields. In this way, synthetic magnetic fields and spin-orbit coupling have been realized, and a supersolid phase has been observed. A supersolid is superfluid and breaks translational symmetry, i.e. it has shape.

We present a verifiable and blind protocol for assisted universal quantum computing on continuous-variable (CV) platforms. This protocol is highly experimentally-friendly to the client, as it only requires Gaussianoperation capabilities from the latter. Moreover, the server is not required universal quantum-computational power either, its only function being to supply the client with copies of a single-mode non-Gaussian state. Universality is attained based on state-injection of the serverʼs non-Gaussian supplies.

We devise an all-optical scheme for the generation of entangled multimode photonic states encoded in temporal modes of light. The scheme employs a nonlinear down-conversion process in an optical loop to generate one- and higher-dimensional tensor network states of light. We illustrate the principle with the generation of two different classes of entangled tensor network states and report on a variational algorithm to simulate the ground-state physics of many-body systems.

The study of high-efficiency magnetization reversal using spin-orbit coupling

In recent years, the magnetic random-access memory (MRAM) have been attracting attention as a next generation memory device due to their fast switching speed and non-volatility characteristics. The biggest challenge for the switching device using a magnetic material is an easy magnetization reversal.
