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…
Fault-tolerant quantum computation by hybrid qubits with bosonic cat-code and single photons
Jaehak Lee, Nuri Kang, Seok-Hyung Lee +3
Hybridizing different degrees of freedom or physical platforms potentially offers various advantages in building scalable quantum architectures. We here introduce a fault-tolerant…
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…
Photonic Hybrid Quantum Computing
Jaehak Lee, Srikrishna Omkar, Yong Siah Teo +4
Photons are a ubiquitous carrier of quantum information: they are fast, suffer minimal decoherence, and do not require huge cryogenic facilities. Nevertheless, their intrinsically…
