Quantum Algorithms for Nonlinear Differential Equations via Pivot-Shifted Carleman Linearization
Ke Wang, Zikang Jia, Shravan Veerapaneni +1
We develop a pivot-shifted Carleman linearization framework for quantum algorithms solving quadratic nonlinear ordinary differential equations. By shifting the dynamics by a pivot…
Flux Pumped Kerr-Free Parametric Amplifier
Kagan Yanik, Irwin Huang, Bibek Bhandari +7
We propose a flux-pumped superconducting parametric amplifier based on symmetrically threaded superconducting quantum interference devices (SQUIDs) that achieves a Kerr-free operat…
Quantum Benchmarking of High-Fidelity Noise-Biased Operations on a Detuned-Kerr-Cat Qubit
Bingcheng Qing, Ahmed Hajr, Ke Wang +19
Ubiquitous noises in quantum systems remain a key obstacle to building quantum computers, necessitating the use of quantum error correction codes. Recently, error-correcting codes…
Symmetrically Threaded Superconducting Quantum Interference Devices As Next Generation Kerr-cat Qubits
Bibek Bhandari, Irwin Huang, Ahmed Hajr +7
We theoretically explore an alternative circuit for Kerr-cat qubits based on symmetrically threaded Superconducting Quantum Interference Devices (SQUID). The Symmetrically Threaded…
High-Coherence Kerr-cat qubit in 2D architecture
Ahmed Hajr, Bingcheng Qing, Ke Wang +15
The Kerr-cat qubit is a bosonic qubit in which multi-photon Schrodinger cat states are stabilized by applying a two-photon drive to an oscillator with a Kerr nonlinearity. The supp…
