Universal Optimization and Tighter Fidelity Bounds for Approximate Quantum Error Correction
Jing Wu, Michele Grossi, Doga Kurkcuoglu +1
Approximate quantum error correction (AQEC) not only dictates the performance of discrete- and continuous-variable quantum error correction codes but also serves as a unifying fram…
Neural-Network Inverse Design of SRF Cavities and Transmons for Bosonic Quantum Computation
Joseph Yaker, Jovan Markovic, Alessandro Reineri +2
Three-dimensional superconducting radio-frequency (SRF) cavities provide exceptionally long-lived electromagnetic modes and, when coupled to nonlinear elements such as transmon qub…
Sparse Phase Ansatzes for Resource-Efficient Qudit State Preparation via the SNAP-Displacement Protocol
Maurizio Ferrari Dacrema, Doga Murat Kurkcuoglu, Andy C. Y. Li +2
Efficient preparation of nonclassical bosonic states is a central requirement for quantum computing, simulation, and precision metrology. We study resource-efficient quantum state…
Ultracoherent superconducting cavity-based multiqudit platform with error-resilient control
Taeyoon Kim, Tanay Roy, Xinyuan You +26
Realizing the promise of quantum computing requires simultaneously increasing Hilbert-space size and coherence times. While qubit-based architectures have long been the dominant pa…
Inference of response functions with the help of machine learning algorithms
Doga Murat Kurkcuoglu, Alessandro Roggero, Gabriel N. Perdue +1
Response functions are a key quantity to describe the near-equilibrium dynamics of strongly-interacting many-body systems. Recent techniques that attempt to overcome the challenges…
