Abstract Among the principal challenge facing scalability in ion trap quantum computers is the full integration of optics, digital electronics, and through-wafer vias into the trap chip. I will discuss Oxford Ionics' strategy for developing ion trap quantum computers with 100s-1000s of ions, then describe some of the methodologies for designing large-scale ion trap electrode…

Abstract Parameterized quantum circuits serve as ansätze for solving variational problems and provide a flexible paradigm for programming near-term quantum computers. Here we discuss three fundamental criteria for this paradigm to be effective: expressibility, trainability and generalizability. We will introduce these concepts and present recent analytic progress quantifying to what extent these criteria can be…

Abstract Standard implementations of quantum error correction in atomic processors devote multiple atoms and many inter-atom gates to each robust qubit.  A co-design strategy to streamline this approach should focus on both tailoring the code to the native hardware errors and reducing the resource cost of the QEC cycle.  Absorption-emission (Æ) codes are designed to…

Abstract Qiskit Functions simplify and accelerate utility-scale algorithm discovery and application development by abstracting away parts of the quantum software development workflow. In this way, Qiskit Functions free up time normally spent hand-writing code and fine-tuning experiments. In this seminar, we will talk about the journey of the IBM Quantum team to release the first…

Abstract The integration of Tensor Networks into quantum computing has unlocked new possibilities, particularly for efficiently loading complex datasets onto quantum systems. In this talk, we examine the tensor-train cross approximation (TT-cross) algorithm as an effective solution to the probability loading challenge in Quantum Monte Carlo (QMC). By applying TT-cross to high-dimensional financial distributions, we…

28th Annual Quantum Information Processing Conference

Abstract Quantum communication is an emerging communication paradigm with no parallel in classical systems. It leverages the unique quantum properties of light to enable unconditionally secure communications and to support new engineering applications, such as distributed quantum computing and sensing. In this talk, I will first present recent progress in quantum communication networks and the…
