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.

IQC Colloquium - Layla Hormozi, IQC

We study the role of Hamiltonian complexity in the performance of quantum annealers. It is well-known that non-stoquastic Hamiltonians are more complex than stoquastic Hamiltonians and universal adiabatic quantum computing is possible when they are employed. Here we ask whether utilizing non-stoquastic Hamiltonians in quantum annealers can lead to a better performance in solving optimization problems.

In ordinary, non-relativistic quantum theory, especially in quantum information, space and time are treated differently. For example, time is a parameter rather than an operator; states are defined across the whole space but only at one time, and then evolve under the prescribed dynamics. These go against our intuition from relativity. Thus, space-time density matrices have been introduced and here we discuss one of these formulations called pseudo-density matrix (PDM) which treats space and time indiscriminately.

 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.

This 7-day conference aims to bring scientists from China and Canada together, to nourish more extensive collaborations and to educate younger generations. The invited talks covers many aspects of quantum technologies, including quantum information theory and implementation, quantum cryptography and quantum communication, quantum materials, quantum metrology, and quantum foundations.

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.
