Purification-based quantum error mitigation of pair-correlated electron simulations
T. E. O'Brien, G. Anselmetti, F. Gkritsis +173
An important measure of the development of quantum computing platforms has been the simulation of increasingly complex physical systems. Prior to fault-tolerant quantum computing,…
Non-Abelian braiding of graph vertices in a superconducting processor
Trond I. Andersen, Yuri D. Lensky, Kostyantyn Kechedzhi +166
Indistinguishability of particles is a fundamental principle of quantum mechanics. For all elementary and quasiparticles observed to date - including fermions, bosons, and Abelian…
Beyond Heisenberg Limit Quantum Metrology through Quantum Signal Processing
Yulong Dong, Jonathan Gross, Murphy Yuezhen Niu
Leveraging quantum effects in metrology such as entanglement and coherence allows one to measure parameters with enhanced sensitivity. However, time-dependent noise can disrupt suc…
Learning quantum systems via out-of-time-order correlators
Thomas Schuster, Murphy Niu, Jordan Cotler +3
Learning the properties of dynamical quantum systems underlies applications ranging from nuclear magnetic resonance spectroscopy to quantum device characterization. A central chall…
Domain-Specific Quantum Architecture Optimization
Wan-Hsuan Lin, Bochen Tan, Murphy Yuezhen Niu +2
With the steady progress in quantum computing over recent years, roadmaps for upscaling quantum processors have relied heavily on the targeted qubit architectures. So far, similarl…
Suppressing quantum errors by scaling a surface code logical qubit
Rajeev Acharya, Igor Aleiner, Richard Allen +154
Practical quantum computing will require error rates that are well below what is achievable with physical qubits. Quantum error correction offers a path to algorithmically-relevant…
Formation of robust bound states of interacting microwave photons
Alexis Morvan, Trond I. Andersen, Xiao Mi +147
Systems of correlated particles appear in many fields of science and represent some of the most intractable puzzles in nature. The computational challenge in these systems arises w…
Noise-resilient Edge Modes on a Chain of Superconducting Qubits
Xiao Mi, Michael Sonner, Murphy Yuezhen Niu +125
Inherent symmetry of a quantum system may protect its otherwise fragile states. Leveraging such protection requires testing its robustness against uncontrolled environmental intera…
Generalized Interference of Fermions and Bosons
Dylan Spivak, Murphy Yuezhen Niu, Barry C. Sanders +1
Using tools from representation theory, we derive expressions for the coincidence rate of partially-distinguishable particles in an interferometry experiment. Our expressions are v…
