Hybrid cat-transmon architecture for scalable, hardware-efficient quantum error correction

Connor T. Hann, Kyungjoo Noh, Harald Putterman +6

Dissipative cat qubits are a promising physical platform for quantum computing, since their large noise bias can enable more hardware-efficient quantum error correction. In this wo…

Preserving phase coherence and linearity in cat qubits with exponential bit-flip suppression

Harald Putterman, Kyungjoo Noh, Rishi N. Patel +17

Cat qubits, a type of bosonic qubit encoded in a harmonic oscillator, can exhibit an exponential noise bias against bit-flip errors with increasing mean photon number. Here, we foc…

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…

Designing high-fidelity two-qubit gates between fluxonium qubits

Emma L. Rosenfeld, Connor T. Hann, David I. Schuster +2

We take a bottom-up, first-principles approach to design a two-qubit gate between fluxonium qubits for minimal error, speed, and control simplicity. Our proposed architecture consi…
