Hardware-efficient quantum error correction via concatenated bosonic qubits
Harald Putterman, Kyungjoo Noh, Connor T. Hann +118
In order to solve problems of practical importance, quantum computers will likely need to incorporate quantum error correction, where a logical qubit is redundantly encoded in many…
Near-ultrastrong nonlinear light-matter coupling in superconducting circuits
Yufeng Ye, Jeremy B. Kline, Alec Yen +9
The interaction between an atom and an electromagnetic mode of a resonator is of both fundamental interest and is ubiquitous in quantum technologies. Most prior work studies a line…
Interferometric Purcell suppression of spontaneous emission in a superconducting qubit
Alec Yen, Yufeng Ye, Kaidong Peng +8
In superconducting qubits, suppression of spontaneous emission is essential to achieve fast dispersive measurement and reset without sacrificing qubit lifetime. We show that resona…
Directional emission of a readout resonator for qubit measurement
Alec Yen, Yufeng Ye, Kaidong Peng +8
We propose and demonstrate transmission-based dispersive readout of a superconducting qubit using an all-pass resonator, which preferentially emits readout photons toward the outpu…
Ultrafast Superconducting Qubit Readout with the Quarton Coupler
Yufeng Ye, Jeremy B. Kline, Sean Chen +1
Fast, high-fidelity, and quantum nondemolition (QND) qubit readout is an essential element of quantum information processing. For superconducting qubits, state-of-the-art readout i…
