    applied math computation grand challenge quantum computer qubits

    Summary

     

    Coherence is essential for quantum computation; yet it introduces a unique sensitivity to any imperfections in hardware design, control systems, and the operating environment. Overcoming these sensitivities requires a hierarchy of strategies, ranging from optimization of the hardware architecture to software solutions including quantum error correction. Randomized Benchmarking Protocols are an important family of tools (developed mostly here in Waterloo) that have become widely adopted to characterize and optimize the performance of one- and two-qubit quantum gates. Moving beyond the current state-of-the-art, we are developing and applying protocols that can characterize, optimize, validate, and certify the overall performance of a many-qubit architecture. We are also working to develop the diagnostics that will guide the design of multi-qubit quantum processors, for example, by clarifying how the quality of quantum control scales with the number of qubits. Ultimately, we expect that this work will sharpen our understanding of the required resources for quantum computation to outperform classical systems.

    Entangled Photon Orbital Angular Momentum Arrays

    Summary Arrays of orbital angular momentum (OAM) states of light are a new form of structured light so far relatively unexplored in quantum information science. Unlike spin angular momentum of light, which is related to light’s polarization and covers two dimensions, OAM states, sometimes described as ‘donut beams’ due to the shape of the field […]

    Towards large area, resonant quantum tunneling diodes by continuous Langmuir transfer of exfoliated 2D materials

    Summary  Atomically thin 2D materials constitute promising building blocks for quantum devices due to their exotic, layer-dependent electronic properties. The ability to stack these materials in alternating layers enables heterostructures to be built in almost limitless combinations and over small enough length scales to observe quantum phenomena. So far though, practical implementation of devices based […]

    Carbon Nanotube Monolayer Josephson Junction Superconducting Qubit

    Carbon nanotubes (CNTs) are a promising material for use in Josephson-Junctions (JJs) given their unique properties, such as high electrical conductivity, pristine surface, inherent nanoscale dimension, and silicon-compatible processing

    Topological Properties of Exciton-Polaritons in a Kagome Lattice as a Solid-state Quantum Simulator

    Summary   In this project, we build a solid-state quantum simulator for engineering a specific Hamiltonian. Quantum simulators are purpose-built devices with little to no need for error correction, thereby making this type of hardware less demanding than universal quantum computers. Our platform consists of exciton-polariton condensates in multiple quantum-wells sandwiched in a semiconductor Bragg […]
