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…

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…

Abstract I discuss how to effectively describe a one-dimensional system of two-component fermions in the regime of strong attractive particle-particle interactions. First, we examine scattering in the corresponding few-body problem, which can be solved analytically using the Bethe ansatz. This approach enables us to engineer effective interactions between the system's relevant degrees of freedom: fermions…
