Quantum-optimized phase closure for robust interferometric imaging
Zhenning Liu, Emil T. Khabiboulline, Lorcan O. Conlon +7
Closure phase enables imaging with ground-based interferometric arrays by canceling telescope-dependent phase errors due to atmospheric fluctuations. It can be obtained by measurin…
Symmetry-preserving quantum compilation
Maryam Mudassar, Zhi-Yuan Wei, Alexander Schuckert +3
Fault-tolerant quantum simulation requires compiling symmetry-preserving time evolutions into discrete gate sets. Standard Clifford+T synthesis can break continuous symmetries even…
Eliminating photon transport in long-baseline optical interferometry using quantum memories
Yousef K. Chahine, Chaohan Cui, William DeRocco +11
In this paper, we describe the fundamental operating mechanisms of optical interferometry using quantum memory and entanglement. We show how these remove the optical delay line bot…
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…
Toward a 2D Local Implementation of Quantum LDPC Codes
Noah Berthusen, Dhruv Devulapalli, Eddie Schoute +4
Geometric locality is an important theoretical and practical factor for quantum low-density parity-check (qLDPC) codes which affects code performance and ease of physical realizati…
Encoding Majorana codes
Maryam Mudassar, Riley W. Chien, Daniel Gottesman
To implement a quantum error correction protocol, we first need a scheme to prepare our state in the correct subspace of the code, and this can be done using a unitary encoding cir…
