Fast-feedback protocols for calibration and drift control in quantum computers
Alicia B. Magann, Nathan E. Miller, Robin Blume-Kohout +2
We introduce two classes of lightweight, adaptive calibration protocols for quantum computers that leverage fast feedback. The first enables shot-by-shot updates to device paramete…
Mid-circuit logic executed in the qubit layer of a quantum processor
Cameron Jones, Piper Wysocki, MengKe Feng +16
Practical quantum computers need to continuously exchange data between classical and quantum subsystems during a computation. Mid-circuit measurements of a qubits state are transfe…
Emergent Non-Markovianity in Logical Qubit Dynamics
Jalan A. Ziyad, Robin Blume-Kohout, Kenneth Rudinger
Logical qubits encoded in quantum error correcting codes can exhibit non-Markovian dynamical evolution, even when the underlying physical noise is Markovian. To understand this eme…
Helios: A 98-qubit trapped-ion quantum computer
Anthony Ransford, M. S. Allman, Jake Arkinstall +183
We report on Quantinuum Helios, a 98-qubit trapped-ion quantum processor based on the quantum charge-coupled device (QCCD) architecture. Helios features Ba hyperfine…
Platform Architecture for Tight Coupling of High-Performance Computing with Quantum Processors
Shane A. Caldwell, Moein Khazraee, Elena Agostini +27
We propose an architecture, called NVQLink, for connecting high-performance computing (HPC) resources to the control system of a quantum processing unit (QPU) to accelerate workloa…
Benchmarking quantum computers with any quantum algorithm
Stefan K. Seritan, Aditya Dhumuntarao, Aidan Q. Wilber-Gauthier +5
Application-based benchmarks are increasingly used to quantify and compare quantum computers' performance. However, because contemporary quantum computers cannot run utility-scale…
Experimental Demonstration of High-Fidelity Logical Magic States from Code Switching
Lucas Daguerre, Robin Blume-Kohout, Natalie C. Brown +2
Preparation of high-fidelity logical magic states has remained as a necessary but daunting step towards building a large-scale fault-tolerant quantum computer. One approach is to f…
Efficient simulation of Clifford circuits with small Markovian errors
Ashe Miller, Corey Ostrove, Jordan Hines +3
Classical simulation of noisy quantum circuits is essential for understanding quantum computing experiments. It enables scalable error characterization, analysis of how noise impac…
Estimating detector error models from syndrome data
Robin Blume-Kohout, Kevin Young
Protecting quantum information using quantum error correction (QEC) requires repeatedly measuring stabilizers to extract error syndromes that are used to identify and correct error…
Quantum Characterization, Verification, and Validation
Robin Blume-Kohout, Timothy Proctor, Kevin Young
Quantum characterization, verification, and validation (QCVV) is a set of techniques to probe, describe, and assess the behavior of quantum bits (qubits), quantum information-proce…
