Cavity-mediated cross-cross-resonance gate
Alexey V. Gorshkov, Daniel Cohen, Arbel Haim +8
We propose a cavity-mediated gate between two transmon qubits or other nonlinear superconducting elements. The gate is realized by driving both qubits at a frequency that is near-r…
A distillation-teleportation protocol for fault-tolerant QRAM
Alexander M. Dalzell, András Gilyén, Connor T. Hann +5
We present a protocol for fault-tolerantly implementing the logical quantum random access memory (QRAM) operation, given access to a specialized, noisy QRAM device. For coherently…
Frequency-noise-insensitive universal control of Kerr-cat qubits
Lennart Maximilian Seifert, Connor T. Hann, Kyungjoo Noh
We theoretically study the influence of frequency uncertainties on the operation of a Kerr-cat qubit. As the mean photon number increases, Kerr-cat qubits provide an increasing lev…
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…
