Symmetry Constrained Quantum Error Mitigation for the Schwinger Model
Alexander Tomlinson, Graham Van Goffrier, Bipasha Chakraborty +1
Quantum error mitigation (QEM) is at the very heart of near-term quantum simulations and lattice gauge theories are no exceptions, rather their physical symmetries provide natural…

Noisy intermediate-scale quantum (NISQ) devices seek to achieve quantum advantage over classical systems without the use of full quantum error correction. We propose a NISQ process…
Quantum Error Mitigated Classical Shadows
Hamza Jnane, Jonathan Steinberg, Zhenyu Cai +2
Classical shadows enable us to learn many properties of a quantum state with very few measurements. However, near-term and early fault-tolerant quantum computers will only be a…
Quantum Error Mitigation
Zhenyu Cai, Ryan Babbush, Simon C. Benjamin +5
For quantum computers to successfully solve real-world problems, it is necessary to tackle the challenge of noise: the errors which occur in elementary physical components due to u…
Looped Pipelines Enabling Effective 3D Qubit Lattices in a Strictly 2D Device
Zhenyu Cai, Adam Siegel, Simon Benjamin
Many quantum computing platforms are based on a two-dimensional physical layout. Here we explore a concept called looped pipelines which permits one to obtain many of the advantage…
