Optimal Fusion Strategies for Quantum Computation
Kenneth Goodenough, Andrew Landahl, Joon Lee +2
Logical fusions are important for a number of tasks in quantum information, such as quantum error correction and quantum repeaters. In the photonic setting one must contend with th…
A small and interesting architecture for early fault-tolerant quantum computers
Jacob S. Nelson, Andrew J. Landahl, Andrew D. Baczewski
We present an architecture for early fault-tolerant quantum computers based on the smallest interesting colour code (Earl Campbell, 2016). It realizes a universal logical gate set…
Requirements for building effective Hamiltonians using quantum-enhanced density matrix downfolding
Shivesh Pathak, Antonio E. Russo, Stefan Seritan +4
Density matrix downfolding (DMD) is a technique for regressing low-energy effective Hamiltonians from quantum many-body Hamiltonians. One limiting factor in the accuracy of classic…
Error mitigation, optimization, and extrapolation on a trapped ion testbed
Oliver G. Maupin, Ashlyn D. Burch, Brandon Ruzic +8
Current noisy intermediate-scale quantum (NISQ) trapped-ion devices are subject to errors which can significantly impact the accuracy of calculations if left unchecked. A form of e…
JaqalPaw: A Guide to Defining Pulses and Waveforms for Jaqal
Daniel Lobser, Joshua Goldberg, Andrew J. Landahl +8
One of the many challenges of developing an open user testbed such as QSCOUT is providing an interface that maintains simplicity without compromising expressibility or control. Thi…
Logical fermions for fault-tolerant quantum simulation
Andrew J. Landahl, Benjamin C. A. Morrison
We show how to absorb fermionic quantum simulation's expensive fermion-to-qubit mapping overhead into the overhead already incurred by surface-code-based fault-tolerant quantum com…
