Dissipatively Stabilized 0-n Fock Qubits for Noise-Biased Quantum Computing
Su Direkci, Simon Lieu, Kyungjoo Noh +1
Noise-biased qubits have bit-flip errors that are exponentially suppressed relative to phase-flip errors, and offer a promising route toward fault-tolerant quantum computing. Howev…
Viewing protected superconducting qubits through the lens of the cat qubit
Simon Lieu, Emma L. Rosenfeld, Kyungjoo Noh +1
We draw analogies between protected superconducting qubits and bosonic qubits by studying the fluxonium Hamiltonian in its Fock basis. The mean-field phase diagram of fluxonium (at…
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…
Cross-resonance control of an oscillator with an auxiliary fluxonium qubit
Guo Zheng, Simon Lieu, Emma L. Rosenfeld +2
The conditional displacement (CD) gate between an oscillator and a discrete-variable auxiliary qubit plays a key role in quantum information processing tasks, such as enabling univ…
