Patchwork: automated lattice surgery and space-time partitioning for real-time decoding
Christopher Chamberland, Muyuan Li, Scott Thornton +3
We introduce patchwork, a lattice-surgery compiler for arbitrary multi-qubit Pauli measurements on a prescribed narrow-corridor two-dimensional surface-code layout. Systematic geom…
Fast and accurate AI-based pre-decoders for color codes
Jan Olle, Christopher Chamberland, Muyuan Li +1
Color codes are promising alternatives to surface codes for universal fault-tolerant quantum computing due to their simpler lattice-surgery protocols and the transversal implementa…
Fast and accurate AI-based pre-decoders for surface codes
Christopher Chamberland, Jan Olle, Muyuan Li +2
Fast, scalable decoding architectures that operate in a block-wise parallel fashion across space and time are essential for real-time fault-tolerant quantum computing. We introduce…
Matching and maximum likelihood decoding of a multi-round subsystem quantum error correction experiment
Neereja Sundaresan, Theodore J. Yoder, Youngseok Kim +7
Quantum error correction offers a promising path for performing quantum computations with low errors. Although a fully fault-tolerant execution of a quantum algorithm remains unrea…
Expressivity of Variational Quantum Machine Learning on the Boolean Cube
Dylan Herman, Rudy Raymond, Muyuan Li +3
Categorical data plays an important part in machine learning research and appears in a variety of applications. Models that can express large classes of real-valued functions on th…
Calibrated decoders for experimental quantum error correction
Edward H. Chen, Theodore J. Yoder, Youngseok Kim +6
Arbitrarily long quantum computations require quantum memories that can be repeatedly measured without being corrupted. Here, we preserve the state of a quantum memory, notably wit…
Demonstration of Shor encoding on a trapped-ion quantum computer
Nhung H. Nguyen, Muyuan Li, Alaina M. Green +5
Fault-tolerant quantum error correction (QEC) is crucial for unlocking the true power of quantum computers. QEC codes use multiple physical qubits to encode a logical qubit, which…
Fault-Tolerant Operation of a Quantum Error-Correction Code
Laird Egan, Dripto M. Debroy, Crystal Noel +8
Quantum error correction protects fragile quantum information by encoding it into a larger quantum system. These extra degrees of freedom enable the detection and correction of err…
A Numerical Study of Bravyi-Bacon-Shor and Subsystem Hypergraph Product Codes
Muyuan Li, Theodore J. Yoder
We provide a numerical investigation of two families of subsystem quantum codes that are related to hypergraph product codes by gauge-fixing. The first family consists of the Bravy…
Logical Performance of 9 Qubit Compass Codes in Ion Traps with Crosstalk Errors
Dripto M. Debroy, Muyuan Li, Shilin Huang +1
We simulate four quantum error correcting codes under error models inspired by realistic noise sources in near-term ion trap quantum computers: dephasing, gate overrotation,…
Stabilizer Slicing: Coherent Error Cancellations in LDPC Codes
Dripto Debroy, Muyuan Li, Michael Newman +1
Coherent errors are a dominant noise process in many quantum computing architectures. Unlike stochastic errors, these errors can combine constructively and grow into highly detrime…
2-D Compass Codes
Muyuan Li, Daniel Miller, Michael Newman +2
The compass model on a square lattice provides a natural template for building subsystem stabilizer codes. The surface code and the Bacon-Shor code represent two extremes of possib…
Direct measurement of Bacon-Shor code stabilizers
Muyuan Li, Daniel Miller, Kenneth R. Brown
A Bacon-Shor code is a subsystem quantum error-correcting code on an lattice where the weight- stabilizers are usually inferred from the measurements of $…
Simulating the performance of a distance-3 surface code in a linear ion trap
Colin J. Trout, Muyuan Li, Mauricio Gutierrez +4
We explore the feasibility of implementing a small surface code with 9 data qubits and 8 ancilla qubits, commonly referred to as surface-17, using a linear chain of 171Yb+ ions. Tw…
Fault Tolerance with Bare Ancillae for a [[7,1,3]] Code
Muyuan Li, Mauricio Gutiérrez, Stanley E. David +2
We present a [[7, 1, 3]] quantum error-correcting code that is able to achieve fault-tolerant syndrome measurement using one ancillary qubit per stabilizer for an error model of in…
