Fault-Tolerant Error Detection Above Break-Even for Multi-Qubit Gates A fully fault-tolerant implementation of the quantum error-detecting Iceberg $[[2m, 2m-2, 2]]$ code applied to a Toffoli circuit achieved beyond-break-even error detection on a leading trapped-ion qua...

Think that error-dectecting codes don't work on a current #Quantumcomputer? Think again! Beyond break-even error supression using the Iceberg code demonstrated in this project for KBR.

Variational Gibbs State Preparation on Trapped-Ion Devices We implement a variational quantum algorithm for Gibbs state preparation of a transverse-field Ising model on IonQ's quantum computers. To this end, we train the variational parameters via classical s...

What are NISQ computers good for? Well, possibly many things. But definitely for the preparation of Gibbs states:

A variational quantum algorithm is implemented on IonQ hardware to prepare Gibbs states of the transverse-field Ising model, with fidelities evaluated via state tomography.

Introducing UNIQuE: The Unconventional Noiseless Intermediate Quantum Emulator We implement an open-source quantum computing emulator that includes arithmetic operations, the quantum Fourier transform, and quantum phase estimation. The emulator provides significant savings in bo...

New paper on #QuantumComputing emulation just posted to @ieeexplore.bsky.social! I was thrilled to share this work at the @ieeeorg.bsky.social #CASCON2025 conference last November. The project @github.com was awarded an IEEE Research Object Reviewed Badge.
