A Quantum Algorithm for Computing All Diagnoses of a Switching Circuit
A. Feldman, J. Kleer, Ion Matei·Sep 8, 2022
Faults are stochastic by nature while most man-made systems, and especially computers, work deterministically. This necessitates the linking of probability theory with mathematical logics, automata, and switching circuit theory. This paper provides s...
Shortest Route to Non-Abelian Topological Order on a Quantum Processor.
Nathanan Tantivasadakarn, R. Verresen, A. Vishwanath·Sep 8, 2022
A highly coveted goal is to realize emergent non-Abelian gauge theories and their anyonic excitations, which encode decoherence-free quantum information. While measurements in quantum devices provide new hope for scalably preparing such long-range en...
Improving the Accuracy of Variational Quantum Eigensolvers with Fewer Qubits Using Orbital Optimization.
Joel Bierman, Yingzhou Li, Jianfeng Lu·Aug 30, 2022
Near-term quantum computers will be limited in the number of qubits on which they can process information as well as the depth of the circuits that they can coherently carry out. To date, experimental demonstrations of algorithms such as the Variatio...

To achieve scalable quantum information processing, great efforts have been devoted to the creation of large-scale entangled states in various physical systems. Ultracold atom in optical lattice is considered as one of the promising platforms due to ...
Shape dependence of entanglement negativity and mutual information in quantum Hall and critical systems
Chia-Chuan Liu, Juliette Geoffrion, William Witczak-Krempa·Aug 26, 2022
We study two entanglement measures in a large family of isotropic many-body states including incompressible quantum Hall liquids and quantum critical systems: the logarithmic negativity (LN), and mutual information (MI). For pure states, obtained for...
Comparison of unknown unitary channels with multiple uses
Yutaka Hashimoto, A. Soeda, M. Murao·Aug 26, 2022
(Dated: Comparison of quantum objects is a task to determine whether two unknown quantum objects are the same or different. It is one of the most basic information processing tasks for learning property of quantum objects, and comparison of quantum st...
Mid-circuit correction of correlated phase errors using an array of spectator qubits
Kevin Singh, C. Bradley, Shraddha Anand +3 more·Aug 24, 2022
Scaling up invariably error-prone quantum processors is a formidable challenge. Although quantum error correction ultimately promises fault-tolerant operation, the required qubit overhead and error thresholds are daunting. In a complementary proposal...
