Local arrows of time in quantum many-body systems
Andrew G. Yates, Jordan Cotler, Nishad Maskara +1
We demonstrate that in quantum many-body systems, local arrows of time can differ from the global time induced by Hamiltonian evolution. That is, within a quantum many-body sys…
Batched high-rate logical operations for quantum LDPC codes
Qian Xu, Hengyun Zhou, Dolev Bluvstein +5
High-rate quantum LDPC (qLDPC) codes reduce memory overhead by densely packing many logical qubits into a single block of physical qubits. Here we extend this concept to high-rate…
Neural Decoders for Universal Quantum Algorithms
J. Pablo Bonilla Ataides, Andi Gu, Susanne F. Yelin +1
Fault-tolerant quantum computing demands decoders that are fast, accurate, and adaptable to circuit structure and realistic noise. While machine learning (ML) decoders have demonst…
Fast simulation of fermions with reconfigurable qubits
Nishad Maskara, Marcin Kalinowski, Daniel Gonzalez-Cuadra +1
Performing large-scale, accurate quantum simulations of many-fermion systems is a central challenge in quantum science, with applications in chemistry, materials, and high-energy p…
Magic tricycles: Efficient magic state generation with finite block-length quantum LDPC codes
Varun Menon, J. Pablo Bonilla-Ataides, Rohan Mehta +3
The preparation of high-fidelity non-Clifford (magic) states is an essential subroutine for universal quantum computation, but imposes substantial space-time overhead. Magic state…
Deconfined quantum criticality on a triangular Rydberg array
Lisa Bombieri, Torsten V. Zache, Gabriele Calliari +3
Fluctuations can drive continuous phase transitions between two distinct ordered phases -- so-called deconfined quantum critical points (DQCPs) -- which lie beyond the Landau-Ginzb…
Architectural mechanisms of a universal fault-tolerant quantum computer
Dolev Bluvstein, Alexandra A. Geim, Sophie H. Li +20
Quantum error correction (QEC) is believed to be essential for the realization of large-scale quantum computers. However, due to the complexity of operating on the encoded `logical…
Fast correlated decoding of transversal logical algorithms
Madelyn Cain, Dolev Bluvstein, Chen Zhao +7
Quantum error correction (QEC) is required for large-scale computation, but incurs a significant resource overhead. Recent advances have shown that by jointly decoding logical qubi…
