The speed of elementary quantum gates, particularly two-qubit ultimately sets the limit on at which circuits can operate. In this work, we experimentally demonstrate commonly used gates nearly fastest possible allowed by physical interaction strength between two superconducting transmon qubits. We achieve implementing experimental designed using a machine-learning-inspired optimal control method. Importantly, our method only requires single-qubit drive to be moderately larger than an...
We investigate a time‐dependent circular billiard with two‐frequency driving function and derive new simplified form for the map, which is symplectic nontwist map. Stability boundaries reconnection thresholds are derived fixed points period‐two vortex pairs. An island interspersal condition such that neighboring chains of first frequency exactly separated by those second. The results show strong enhancement KAM barrier to chaotic diffusion increasing second content overall amplitude.
Routh's second method is modified to treat the spectral stability of equilibria hamiltonian flows and periodic orbits symplectic maps.
The detection errors of a single-bit digital crosscorrelator for detecting bandlimited Gaussian reflections in noise are investigated, and the probability-density function correlator output due to finite-interval crosscorrelation corruption received waveform by wideband is derived compared with experimental results.
The derivation of the single-bit crosscorrelation function a bandlimited Gaussian waveform and two reflections corrupted by wideband noise is given. It seen that waveforms should not be used in detectors when low extraneous levels double simultaneous can expected.
The detection errors of a digital crosscorrelator, utilising severely clipped, bandlimited Gaussian waveforms are investigated, and the probability distribution correlator output due to finite-duration distortion by wideband noise is derived compared with experimental results.
