Simulating Quantum Error Correction beyond Pauli Stochastic Errors
Jordan Hines, Corey Ostrove, Kenneth Rudinger +4
Quantum error correction (QEC), the lynchpin of fault-tolerant quantum computing (FTQC), is designed and validated against well-behaved Pauli stochastic error models. But in real-w…
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…
Detailed, interpretable characterization of mid-circuit measurement on a transmon qubit
Piper C. Wysocki, Luke D. Burkhart, Madeline H. Morocco +12
Mid-circuit measurements (MCMs) are critical components of the quantum error correction protocols expected to enable utility-scale quantum computing. MCMs can be modeled by quantum…
Establishing trust in quantum computations
Timothy Proctor, Stefan Seritan, Erik Nielsen +4
Quantum computing hardware has grown sufficiently complex that it often can no longer be simulated by classical computers, but its computational power remains limited by errors. Th…
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…
