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.

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.

The Quantum Innovators in Computer Science and Mathematics workshop brings together promising young researchers working on theoretical aspects of quantum information and computation in computer science and mathematics. Guests are invited for a four-day conference aimed at exploring the frontier of our field.
