Continuous-angle logical rotations in the Steane code
Eric Huang, Daiwei Zhu, Matteo Ippoliti +2
We experimentally demonstrate continuous-angle logical rotations in the Steane code on the IonQ Forte trapped-ion processor. A round of the protocol applies a trans…

Provable random-matrix spectral ramp in a static, geometrically local Hamiltonian
Matteo Ippoliti
Quantum chaos is commonly associated with the emergence of random-matrix statistics in the spectra of quantum systems. A useful diagnostic is provided by the spectral form factor (…

Emergent unitary designs for encoded qubits from coherent errors and syndrome measurements
Zihan Cheng, Eric Huang, Vedika Khemani +2
Unitary -designs are distributions of unitary gates that match the Haar distribution up to its -th statistical moment. They are a crucial resource for randomized quantum prot…
