# Welcome to the Institute for Quantum Computing

The Institute for Quantum Computing (IQC) is a scientific research institute at the University of Waterloo. The research happening at IQC harnesses the quantum laws of nature in order to develop powerful new technologies and drive future economies.

## What is quantum computing?

Start with our Quantum computing 101 page. It's a quick start guide on quantum computing to help you understand some of the basic principles of quantum mechanics.

## Delivering on the quantum promise

The Transformative Quantum Technologies (TQT) program at the University of Waterloo aims to advance the use of quantum mechanics from laboratory curiosity to an impactful device.

1. Nov. 25, 2019Fine-grained quantum supremacy

Tomoyuki Morimae, Kyoto University

It is known that several sub-universal quantum computing models, such as the IQP model, Boson sampling model, and the one-clean qubit model, cannot be classically simulated unless the polynomial-time hierarchy collapses. However, these results exclude only polynomial-time classical simulations. In this talk, based on fine-grained complexity conjectures, I show more fine-grained" quantum supremacy results that prohibit certain exponential-time classical simulations.

2. Nov. 25, 2019Interfacing Spins and Photons in Solids: Old Friends & New

Mete Atature, The University of Cambridge

Optically active spins in solids offer exciting opportunities as scalable and feasible quantum-optical devices. Numerous material platforms including diamond, semiconductors, and atomically thin 2d materials are under investigation, where each platform brings some advantages of control and feasibility along with other challenges. The inherently mesoscopic nature of solid-state platforms leads to a multitude of dynamics between spins, charges, vibrations and light.

3. Dec. 2, 2019Quantum Information Processing with Spins in Cold Atomic Ensembles

Ivan Deutsch, University of New Mexico

Atomic spins are natural carriers of quantum information given their long coherence time and our capabilities to coherently control and measure them with magneto-optical fields. In this seminar I will describe two paradigms for quantum information processing with ensembles of spin in cold atoms. The strong electric dipole-dipole interactions arising when atoms are excited to high-lying Rydberg states is a powerful method for designing entangling interactions in neutral atoms.
