Trading Circuit Depth for Pulse Sparsity in Chromatic Dynamical Decoupling
Amy F. Brown, Daniel A. Lidar
Suppressing decoherence and crosstalk systematically across large networks of qubits is a pressing concern as qubit counts increase rapidly. General multi-qubit dynamical decouplin…
Digital-Analog-Digital Quantum Supremacy
Daniel Lidar
Quantum supremacy has been explored extensively in gate-model settings. Here, we introduce a quantum-supremacy framework for a hybrid digital-analog-digital quantum computing (DADQ…
Computational Complexity and Simulability of Non-Hermitian Quantum Dynamics
Brian Barch, Daniel Lidar
Non-Hermitian (NH) quantum systems demonstrate striking differences from their Hermitian counterparts, leading to claims of NH advantage in areas ranging from metrology to entangle…
Quantum Fourier Transform using Dynamic Circuits
Elisa Bäumer, Vinay Tripathi, Alireza Seif +2
In dynamic quantum circuits, classical information from mid-circuit measurements is fed forward during circuit execution. This emerging capability of quantum computers confers nume…
Dynamically Generated Decoherence-Free Subspaces and Subsystems on Superconducting Qubits
Gregory Quiroz, Bibek Pokharel, Joseph Boen +7
Decoherence-free subspaces and subsystems (DFS) preserve quantum information by encoding it into symmetry-protected states unaffected by decoherence. An inherent DFS of a given exp…
Error budget of parametric resonance entangling gate with a tunable coupler
Eyob A. Sete, Vinay Tripathi, Joseph A. Valery +2
We analyze the experimental error budget of parametric resonance gates in a tunable coupler architecture. We identify and characterize various sources of errors, including incohere…
Low overhead universality and quantum supremacy using only -control
Brian Barch, Razieh Mohseninia, Daniel Lidar
We consider a model of quantum computation we call "Varying-" (V), defined by applying controllable -diagonal Hamiltonians in the presence of a uniform and constant extern…
