On Error Thresholds for Pauli Channels: Some answers with many more questions
Avantika Agarwal, Alan Bu, Amolak Ratan Kalra +3
This paper focuses on error thresholds for Pauli channels. We numerically compute lower bounds for the thresholds using the analytic framework of coset weight enumerators pioneered…

Low-depth fermion routing without ancillas
Nathan Constantinides, Jeffery Yu, Dhruv Devulapalli +6
Routing is the task of permuting qubits in such a way that quantum operations can be parallelized maximally, given constraints on the hardware geometry. When simulating fermions in…

Improved Clifford operations in constant commutative depth
Richard Cleve, Zhiqian Ding, Luke Schaeffer
The commutative depth model allows gates that commute with each other to be performed in parallel. We show how to compute Clifford operations in constant commutative depth more eff…
