Optimal dynamical decoupling in the presence of colored control noise
Ido Almog, Gil Loewenthal, Jonathan Coslovsky +2
An optimal dynamical decoupling of a quantum system coupled to a noisy environment must take into account also the imperfections of the control pulses. We present a new formalism w…
Addressing Two-Level Systems Variably Coupled to an Oscillating Field
Nir Navon, Shlomi Kotler, Nitzan Akerman +3
We propose a simple method to spectrally resolve single-spins in a cold atomic system, thus realizing single-spin addressing. This scheme uses a dressing field with a spatially-dep…
Observation of anomalous diffusion and fractional self-similarity in one dimension
Yoav Sagi, Miri Brook, Ido Almog +1
We experimentally study anomalous diffusion of ultra-cold atoms in a one dimensional polarization optical lattice. The atomic spatial distribution is recorded at different times an…
Direct Measurement of the System-Environment Coupling as a Tool For Understanding Decoherence and Dynamical Decoupling
Ido Almog, Yoav Sagi, Goren Gordon +3
Decoherence is a major obstacle to any practical implementation of quantum information processing. One of the leading strategies to reduce decoherence is dynamical decoupling --- t…
Motional Broadening in Ensembles With Heavy-Tail Frequency Distribution
Yoav Sagi, Rami Pugatch, Ido Almog +2
We show that the spectrum of an ensemble of two-level systems can be broadened through `resetting' discrete fluctuations, in contrast to the well-known motional-narrowing effect. W…
Process tomography of dynamical decoupling in a dense optically trapped atomic ensemble
Yoav Sagi, Ido Almog, Nir Davidson
Atomic ensembles have many potential applications in quantum information science. Owing to collective enhancement, working with ensembles at high densities increases the overall ef…
