Quantifying the magic of quantum channels

X Wang, MM Wilde, Y Su - New Journal of Physics, 2019 - iopscience.iop.org
To achieve universal quantum computation via general fault-tolerant schemes, stabilizer
operations must be supplemented with other non-stabilizer quantum resources. Motivated …

Ultracold polar molecules as qudits

R Sawant, JA Blackmore, PD Gregory… - New Journal of …, 2020 - iopscience.iop.org
We discuss how the internal structure of ultracold molecules, trapped in the motional ground
state of optical tweezers, can be used to implement qudits. We explore the rotational, fine …

Molecular asymmetry and optical cycling: laser cooling asymmetric top molecules

BL Augenbraun, JM Doyle, T Zelevinsky, I Kozyryev - Physical Review X, 2020 - APS
We present a practical roadmap to achieve optical cycling and laser cooling of asymmetric
top molecules (ATMs). Our theoretical analysis describes how reduced molecular symmetry …

computation. The protocol's overhead, defined as the number of input magic states required …

Morphing quantum codes

M Vasmer, A Kubica - PRX Quantum, 2022 - APS
We introduce a morphing procedure that can be used to generate new quantum codes from
existing quantum codes. In particular, we morph the 15-qubit Reed-Muller code to obtain a …

Quantifying multiqubit magic channels with completely stabilizer-preserving operations

G Saxena, G Gour - Physical Review A, 2022 - APS
In this paper we extend the resource theory of magic states to the channel domain by
considering completely stabilizer-preserving operations (CSPOs) as free. We introduce and …
