We propose families of protocols for magic-state distillation-important components of fault-tolerance schemes-for systems of odd prime dimension. Our protocols utilize quantum Reed-Muller codes with transversal non-Clifford gates. We find that, in higher dimensions, small and effective codes can be used that have no direct analogue in qubit (two-dimensional) systems. We present several concrete protocols, including schemes for three-dimensional (qutrit) and five-dimensional (ququint) systems. The five-dimensional protocol is, by many measures, the best magic-state-distillation scheme yet discovered. It excels both in terms of error threshold with respect to depolarizing noise (36.3%) and the efficiency measure known as yield, where, for a large region of parameters, it outperforms its qubit counterpart by many orders of magnitude.

Cellular automaton decoders for topological quantum codes with noisy measurements and beyond

Michael Vasmer, Dan E. Browne, Aleksander Kubica

Summary: The proposed error correction procedure based on a cellular automaton, the sweep rule, is applicable to a broad range of codes, particularly the toric code. Numerical benchmarks show that the procedure is robust against measurement errors and insensitive to lattice and noise model details. This work represents a step towards finding simple and high-performance decoding strategies for a wide range of quantum low-density parity-check codes.

Limitations on Transversal Gates for Hypergraph Product Codes

Simon Burton, Dan Browne

Summary: This paper introduces a new technique for limiting the gates of hypergraph product codes in fault-tolerant quantum computers. It provides a necessary condition on these codes and conjectures that this condition applies to a class of Gallagher codes.

Software mitigation of coherent two-qubit gate errors

Lingling Lao, Alexander Korotkov, Zhang Jiang, Wojciech Mruczkiewicz, Thomas E. O'Brien, Dan E. Browne

Summary: This work presents two software methods to mitigate parasitic errors in two-qubit gates in quantum computing. The first approach utilizes the Cartan's KAK decomposition and applies single-qubit rotations to counteract parasitic gates without additional overhead. The second approach uses a numerical optimization algorithm to recompile a target unitary into the error-parasitic two-qubit gate plus single-qubit gates. The results show that different approaches have advantages in different error regimes, providing guidance for error mitigation in near-term quantum computers.

Universality of Z3 parafermions via edge-mode interaction and quantum simulation of topological space evolution with Rydberg atoms

Asmae Benhemou, Toonyawat Angkhanawin, Charles S. Adams, Dan E. Browne, Jiannis K. Pachos

Summary: The researchers investigate the generation of quantum gates by allowing Z3 parafermions to interact, achieving universality. They study the form of the nontopological gate that arises through direct short-range interaction of the parafermion edge modes in a Z3 parafermion chain. The interaction gives rise to a dynamical phase gate on the encoded ground space, generating a non-Clifford gate which can be tuned to belong to even levels of the Clifford hierarchy. The researchers propose an experiment that simulates the braiding and dynamical evolutions of the Z3 topological states with Rydberg atom technology.

Non-Pauli errors in the three-dimensional surface code

Thomas R. Scruby, Michael Vasmer, Dan E. Browne

Summary: Stabilizer error correcting codes have the ability to project arbitrary errors to Pauli errors, simplifying the physical error correction process. However, logical non-Clifford operations can introduce additional correlations, and previous studies have shown the existence of nonlocal linking charge phenomena in the context of applying a transversal T gate to the three-dimensional color code.

2QAN: A quantum compiler for 2-local qubit Hamiltonian simulation algorithms

Lingling Lao, Dan E. Browne

Summary: Researchers developed a quantum compiler named 2QAN to optimize quantum circuits for 2-local qubit Hamiltonian simulation problems. The compiler uses permutation-aware techniques for qubit routing, gate optimization, and scheduling to minimize compilation overhead and achieves better performance than existing compilers.

Numerical Implementation of Just-In-Time Decoding in Novel Lattice Slices Through the Three-Dimensional Surface Code

T. R. Scruby, D. E. Browne, P. Webster, M. Vasmer

Summary: This study develops and simulates an explicit recipe for just-in-time decoding scheme in three-dimensional surface codes, based on recent work by B. Brown. It can implement a transversal CCZ operation between three two-dimensional surface codes in linear time. The study presents detailed bounded-height lattice slices through the three-dimensional codes, which retain the code distance and measurement-error detecting properties while allowing dimension-jumping process to expand from/collapse to two-dimensional surface codes on the slice boundaries. The simulation results show a threshold p(c) similar to 0.1% in all three codes, indicating potential for improvement with decoder optimization.

Designing Calibration and Expressivity-Efficient Instruction Sets for Quantum Computing

Lingling Lao, Prakash Murali, Margaret Martonosi, Dan Browne

Summary: The study aims to balance between application expressivity and calibration overhead in near-term quantum computing systems. By using numerical optimization, NuOp efficiently decomposes application operations into different hardware gate types. Results show that implementing 4-8 types of 2Q gates can achieve similar expressivity as a full continuous gate family while significantly reducing calibration overheads.

Quantum state discrimination using noisy quantum neural networks

Andrew Patterson, Hongxiang Chen, Leonard Wossnig, Simone Severini, Dan Browne, Ivan Rungger

Summary: In the near term, noisy quantum computers require algorithms with low circuit depth and qubit count. Research shows that introducing a smaller circuit ansatz can overcome the limitations of gradient calculation on noisy devices with a large number of parameters. The main effect of noise is to increase the overlap between states as circuit gates are applied, making discrimination more challenging.
