Codesign of quantum error-correcting codes and modular chiplets in the presence of defects
S. Lin, Joshua Viszlai, Kaitlin N. Smith +4 more·Apr 29, 2023
Fabrication errors pose a significant challenge in scaling up solid-state quantum devices to the sizes required for fault-tolerant (FT) quantum applications. To mitigate the resource overhead caused by fabrication errors, we combine two approaches: (...
Zero Noise Extrapolation on Logical Qubits by Scaling the Error Correction Code Distance
Misty Wahl, A. Mari, Nathan Shammah +2 more·Apr 28, 2023
In this work, we migrate the quantum error mitigation technique of Zero-Noise Extrapolation (ZNE) to fault-tolerant quantum computing. We employ ZNE on logically encoded qubits rather than physical qubits. This approach will be useful in a regime whe...
Avoiding barren plateaus in the variational determination of geometric entanglement
L. Zambrano, A. Muñoz-Moller, M. Muñoz +2 more·Apr 26, 2023
The barren plateau (BP) phenomenon is one of the main obstacles to implementing variational quantum algorithms in the current generation of quantum processors. Here, we introduce a method capable of avoiding the BP phenomenon in the variational deter...
Phase transitions in random circuit sampling
A. Morvan, B. Villalonga, X. Mi +180 more·Apr 21, 2023
Undesired coupling to the surrounding environment destroys long-range correlations in quantum processors and hinders coherent evolution in the nominally available computational space. This noise is an outstanding challenge when leveraging the computa...
Phase transition in magic with random quantum circuits
Pradeep Niroula, C. White, Qingfeng Wang +5 more·Apr 20, 2023
Magic is a property of quantum states that enables universal fault-tolerant quantum computing using simple sets of gate operations. Understanding the mechanisms by which magic is created or destroyed is, therefore, a crucial step towards efficient an...
An Analysis of the Completion Time of the BB84 Protocol
Sounak Kar, J. L. Boudec·Apr 20, 2023
The BB84 QKD protocol is based on the idea that the sender and the receiver can reconcile a certain fraction of the teleported qubits to detect eavesdropping or noise and decode the rest to use as a private key. Under the present hardware infrastruct...
Tutorial: calibration refinement in quantum annealing
K. Chern, K. Boothby, Jack Raymond +2 more·Apr 20, 2023
Quantum annealing has emerged as a powerful platform for simulating and optimizing classical and quantum Ising models. Quantum annealers, like other quantum and/or analog computing devices, are susceptible to non-idealities including crosstalk, devic...
Advancements in Superconducting Microwave Cavities and Qubits for Quantum Information Systems
A. Krasnok, P. Dhakal, A. Fedorov +3 more·Apr 18, 2023
Superconducting microwave cavities with ultra-high Q-factors are revolutionizing the field of quantum computing, offering long coherence times exceeding 1 ms, which is critical for realizing scalable multi-qubit quantum systems with low error rates. ...

Jorge Miguel-Ramiro, Zheng Shi, Luca Dellantonio +3 more·Apr 17, 2023
Overcoming the influence of noise and imperfections is a major challenge in quantum computing. Here, we present an approach based on applying a desired unitary computation in superposition between the system of interest and some auxiliary states. We ...
Multispin Clifford codes for angular momentum errors in spin systems
Sivaprasad Omanakuttan, J. Gross·Apr 17, 2023
The physical symmetries of a system play a central role in quantum error correction. In this work we encode a qubit in a collection of systems with angular-momentum symmetry (spins), extending the tools developed in Phys. Rev. Lett. 127, 010504 for s...
Leakage Benchmarking for Universal Gate Sets
Bujiao Wu, Xiaoyang Wang, Xiao Yuan +2 more·Apr 16, 2023
Errors are common issues in quantum computing platforms, among which leakage is one of the most-challenging to address. This is because leakage, i.e., the loss of information stored in the computational subspace to undesired subspaces in a larger Hil...
The END: An Equivariant Neural Decoder for Quantum Error Correction
E. Egorov, Roberto Bondesan, M. Welling·Apr 14, 2023
Quantum error correction is a critical component for scaling up quantum computing. Given a quantum code, an optimal decoder maps the measured code violations to the most likely error that occurred, but its cost scales exponentially with the system si...
