Protected measurements for protected superconducting qubits
Xanda C Kolesnikow, Thomas B Smith, Andrew C Doherty
Protected superconducting qubits such as the - qubit promise to substantially suppress error rates, facilitating fault-tolerant quantum computing with fewer qubits. Measuring…
Error correction on an array of superconducting qubits with defective components
Julien M. Drouet, Xanda C. Kolesnikow, Campbell K. McLauchlan +6
The paper experimentally compares methods for handling defective qubits and couplers in a superconducting qubit array, showing that excluding underperforming components significant…
Scalable quantum error correction tailored for a heavy-hex qubit array
Seok-Hyung Lee, Xanda C. Kolesnikow, Jun Zen +7
To produce an operable quantum computer that is made with imperfect hardware, we must design and test scalable quantum error correcting codes that are suited for the devices we can…
Low-valency scalable quantum error correction with a dynamic compass code
Jun Zen, Xanda C. Kolesnikow, Campbell K. McLauchlan +6
The ongoing development of hardware that is capable of reliably executing general quantum algorithms requires quantum error-correcting codes that are both practical for realisation…
Protected phase gate for the - qubit using its internal modes
Xanda C Kolesnikow, Thomas B Smith, Felix Thomsen +2
Protected superconducting qubits such as the - qubit promise to substantially reduce physical error rates. However, a key challenge in the field is designing gates for these…
