Preparing Fermions via Classical Sampling and Linear Combinations of Unitaries
Erik J. Gustafson, Henry Lamm
We present an extension of the Evolving density matrices on Qubits (EOQ) framework that enables efficient fault-tolerant preparation of fermionic quantum states. The original m…

Magic State Distillation using Asymptotically Good Codes on Qudits
Michael J. Cervia, Henry Lamm, Diyi Liu +2
Qudits offer the potential for low-overhead magic state distillation, although previous results for asymptotically good codes have required qudit dimension or code lengt…

Synthesis of Single Qutrit Circuits from Clifford+R
Erik J. Gustafson, Henry Lamm, Diyi Liu +2
We present two deterministic algorithms to approximate single-qutrit gates. These algorithms utilize the Clifford + group to find the best approximation of diagonal ro…
