Near-optimal dynamical decoupling of a qubit.

چکیده
We present a near-optimal quantum dynamical decoupling scheme that eliminates general decoherence of a qubit to order n using O(n2) pulses, an exponential decrease in pulses over all previous decoupling methods. Numerical simulations of a qubit coupled to a spin bath demonstrate the superior performance of the new pulse sequences.

Exact solution for the dynamical decoupling of a qubit with telegraph noise
We study the dissipative dynamics of a qubit that is afflicted by classical random telegraph noise and is subject to dynamical decoupling. We derive exact formulas for the qubit dynamics at arbitrary working points in the limit of infinitely strong control pulses bang-bang control , and we investigate in great detail the efficiency of the dynamical decoupling techniques for both Gaussian and no...
متن کاملQuadratic dynamical decoupling: Universality proof and error analysis
We prove the universality of the generalized QDDN1N2 (quadratic dynamical decoupling) pulse sequence for near-optimal suppression of general single-qubit decoherence. Earlier work showed numerically that this dynamical decoupling sequence, which consists of an inner Uhrig DD (UDD) and outer UDD sequence using N1 and N2 pulses, respectively, can eliminate decoherence to O(T N ) using O(N 2) uneq...
متن کاملRigorous bounds for optimal dynamical decoupling
We present rigorous performance bounds for the optimal dynamical decoupling pulse sequence protecting a quantum bit (qubit) against pure dephasing. Our bounds apply under the assumption of instantaneous pulses and of bounded perturbing environment and qubit-environment Hamiltonians such as those realized by baths of nuclear spins in quantum dots. We show that if the total sequence time is fixed...
متن کاملOptimal digital dynamical decoupling for general decoherence via Walsh modulation
We provide a general framework for constructing digital dynamical decoupling sequences based on Walsh modulation — applicable to arbitrary qubit decoherence scenarios. By establishing equivalence between decoupling design based on Walsh functions and on concatenated projections, we identify a family of optimal Walsh sequences, which can be exponentially more efficient, in terms of the required ...
متن کاملDynamical decoupling using slow pulses: Efficient suppression of 1Õf noise
The application of dynamical decoupling pulses to a single qubit interacting with a linear harmonic oscillator bath with 1/f ~more generally, strong low-frequency! spectral density is studied, and compared to the Ohmic case. Decoupling pulses that are slower than the fastest bath time scale are shown to drastically reduce the decoherence rate in the 1/f case. Contrary to conclusions drawn from ...
