Measuring gravitational lensing time delays with quantum information processing
Zhenning Liu, William DeRocco, Shiming Gu +6
The gravitational fields of astrophysical bodies bend the light around them, creating multiple paths along which light from a distant source can arrive at Earth. Measuring the diff…
Fault tolerant Operations in Majorana-based Quantum Codes: Gates, Measurements and High Rate Constructions
Maryam Mudassar, Alexander Schuckert, Daniel Gottesman
Majorana-based quantum computation in nanowires and neutral atoms has gained prominence as a promising platform to encode qubits and protect them against noise. In order to run com…
Adaptive Syndrome Extraction
Noah Berthusen, Shi Jie Samuel Tan, Eric Huang +1
Device error rates on current quantum computers have improved enough to where demonstrations of error correction below break-even are now possible. Still, the circuits required for…
Low-depth quantum symmetrization
Zhenning Liu, Andrew M. Childs, Daniel Gottesman
Quantum symmetrization is the task of transforming a non-strictly increasing list of integers into an equal superposition of all permutations of the list (or more generally, pe…
A Criterion for Post-Selected Quantum Advantage
Chaitanya Karamchedu, Matthew Fox, Daniel Gottesman
Assuming the polynomial hierarchy is infinite, we prove a sufficient condition for determining if uniform and polynomial size quantum circuits over a non-universal gate set are not…
