Error correction on an array of superconducting qubits with defective components
Julien M. Drouet, Xanda C. Kolesnikow, Campbell K. McLauchlan +6
A solid-state quantum-computing architecture will require the fabrication of arrays of many coupled qubits. It is inevitable that this process will produce qubits and couplers with…
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…
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…
Graph-theoretical optimization of fusion-based graph state generation
Seok-Hyung Lee, Hyunseok Jeong
Graph states are versatile resources for various quantum information processing tasks, including measurement-based quantum computing and quantum repeaters. Although the type-II fus…
Virtual distillation with noise dilution
Yong Siah Teo, Seongwook Shin, Hyukgun Kwon +2
Virtual distillation is an error-mitigation technique that reduces quantum-computation errors without assuming the noise type. In scenarios where the user of a quantum circuit is r…
Parity-encoding-based quantum computing with Bayesian error tracking
Seok-Hyung Lee, Srikrishna Omkar, Yong Siah Teo +1
Measurement-based quantum computing (MBQC) in linear optical systems is promising for near-future quantum computing architecture. However, the nondeterministic nature of entangling…
All-photonic architectural roadmap for scalable quantum computing using Greenberger-Horne-Zeilinger states
Srikrishna Omkar, Seok-Hyung Lee, Yong Siah Teo +2
Linear optical quantum computing is beset by the lack of deterministic entangling operations besides photon loss. Motivated by advancements at the experimental front in determinist…
Universal resource-efficient topological measurement-based quantum computation via color-code-based cluster states

Topological measurement-based quantum computation (MBQC) enables one to carry out universal fault-tolerant quantum computation via single-qubit Pauli measurements with a family of…
Loss-tolerant concatenated Bell-state measurement with encoded coherent-state qubits for long-range quantum communication
Seok-Hyung Lee, Seung-Woo Lee, Hyunseok Jeong
The coherent-state qubit is a promising candidate for optical quantum information processing due to its nearly-deterministic nature of the Bell-state measurement (BSM). However, it…
Loss-tolerant transmission of multiphoton-qubit information via hybrid entanglement
Seongjeon Choi, Seok-Hyung Lee, Hyunseok Jeong
It was shown that using multiphoton qubits, a nearly deterministic Bell-state measurement can be performed with linear optics and on-off photodetectors [Phys. Rev. Lett. 114, 11360…
