Trade-offs in Gauss's law error correction for lattice gauge theory quantum simulations
Balint Pato, Natalie Klco
Gauss's law-based quantum error correction (GLQEC) offers a promising approach to reducing qubit overhead in lattice gauge theory simulations by leveraging built-in symmetries. For…
Hyper-optimized Quantum Lego Contraction Schedules
Balint Pato, June Vanlerberghe, Kenneth R. Brown
Calculating the quantum weight enumerator polynomial (WEP) is a valuable tool for characterizing quantum error-correcting (QEC) codes, but it is computationally hard for large or c…
Logical coherence in 2D compass codes
Balint Pato, J. Wilson Staples, Kenneth R. Brown
2D compass codes are a family of quantum error-correcting codes that contain the Bacon-Shor codes, the -Shor and -Shor codes, and the rotated surface codes. Previous numerica…
Concatenated Steane code with single-flag syndrome checks
Balint Pato, Theerapat Tansuwannont, Kenneth R. Brown
A fault-tolerant error correction (FTEC) protocol with a high error suppression rate and low overhead is very desirable for the near-term implementation of quantum computers. In th…
Optimization tools for distance-preserving flag fault-tolerant error correction
Balint Pato, Theerapat Tansuwannont, Shilin Huang +1
Lookup table decoding is fast and distance-preserving, making it attractive for near-term quantum computer architectures with small-distance quantum error-correcting codes. In this…
Adaptive syndrome measurements for Shor-style error correction
Theerapat Tansuwannont, Balint Pato, Kenneth R. Brown
The Shor fault-tolerant error correction (FTEC) scheme uses transversal gates and ancilla qubits prepared in the cat state in syndrome extraction circuits to prevent propagation of…
Observation of Time-Crystalline Eigenstate Order on a Quantum Processor
Xiao Mi, Matteo Ippoliti, Chris Quintana +102
Quantum many-body systems display rich phase structure in their low-temperature equilibrium states. However, much of nature is not in thermal equilibrium. Remarkably, it was recent…
Exponential suppression of bit or phase flip errors with repetitive error correction
Zijun Chen, Kevin J. Satzinger, Juan Atalaya +88
Realizing the potential of quantum computing will require achieving sufficiently low logical error rates. Many applications call for error rates in the regime, but state…
Information Scrambling in Computationally Complex Quantum Circuits
Xiao Mi, Pedram Roushan, Chris Quintana +90
Interaction in quantum systems can spread initially localized quantum information into the many degrees of freedom of the entire system. Understanding this process, known as quantu…
Accurately computing electronic properties of a quantum ring
C. Neill, T. McCourt, X. Mi +89
A promising approach to study condensed-matter systems is to simulate them on an engineered quantum platform. However, achieving the accuracy needed to outperform classical methods…
