Scalable Fluxonium Quantum Processors via Tunable-Coupler Architecture
Ze Zhan, Zishuo Li, Fei Wang +24
Superconducting quantum processors have largely converged on transmon-based architectures, while alternative qubit modalities with intrinsic error protection have lacked a demonstr…
Converting qubit relaxation into erasures with a single fluxonium
Chenlu Liu, Yulong Li, Jiahui Wang +9
Qubits that experience predominantly erasure errors offer distinct advantages for fault-tolerant operation. Indeed, dual-rail encoded erasure qubits in superconducting cavities and…
Global Parametric Gates for Multi-qubit Entanglement
Jize Yang, Lin Guo, Haonan Xiong +8
We propose and experimentally demonstrate a global parametric gate that generates multi-qubit entangled states in a single step. By applying a parametric drive to a common qubit at…
Scalable Low-overhead Superconducting Non-local Coupler with Exponentially Enhanced Connectivity
Haonan Xiong, Jiahui Wang, Juan Song +8
Quantum error correction codes with non-local connections such as quantum low-density parity-check (qLDPC) incur lower overhead and outperform surface codes on large-scale devices.…
A cryogenic on-chip microwave pulse generator for large-scale superconducting quantum computing
Zenghui Bao, Yan Li, Zhiling Wang +7
For superconducting quantum processors, microwave signals are delivered to each qubit from room-temperature electronics to the cryogenic environment through coaxial cables. Limited…
Frequency-tunable microwave quantum light source based on superconducting quantum circuits
Yan Li, Zhiling Wang, Zenghui Bao +7
A nonclassical light source is essential for implementing a wide range of quantum information processing protocols, including quantum computing, networking, communication, and metr…
An ultra-high gain single-photon transistor in the microwave regime
Zhiling Wang, Zenghui Bao, Yan Li +9
A photonic transistor that can switch or amplify an optical signal with a single gate photon requires strong non-linear interaction at the single-photon level. Circuit quantum elec…
Experimental preparation of generalized cat states for itinerant microwave photons
Zenghui Bao, Zhiling Wang, Yukai Wu +11
Generalized cat states represent arbitrary superpositions of coherent states, which are of great importance in various quantum information processing protocols. Here we demonstrate…
A flying Schrödinger cat in multipartite entangled states
Zhiling Wang, Zenghui Bao, Yukai Wu +11
Schrödinger's cat originates from the famous thought experiment querying the counterintuitive quantum superposition of macroscopic objects. As a natural extension, several "cats" (…
