Decoherence suppression for oscillator-assisted geometric quantum gates via symmetrization

We propose a novel symmetrization procedure to beat decoherence for oscillator-assisted quantum gate operations. The enacted symmetry is related to the global geometric features of qubits transformation based on ancillary oscillator modes, e.g. phonons in an ion-trap system. It is shown that the devised multi-circuit symmetrized evolution endows the system with a two-fold resilience against dec...

Sobolev Inequalities: Symmetrization and Self Improvement via Truncation

We develop a new method to obtain symmetrization inequalities of Sobolev type. Our approach leads to new inequalities and considerable simplification in the theory of embeddings of Sobolev spaces based on rearrangement invariant spaces.

Symmetrization, convexity and applications

Based on permutation enumeration of the symmetric group and ‘generalized’ barycentric coordinates on arbitrary convex polytope, we develop a technique to obtain symmetrization procedures for functions that provide a unified framework to derive new Hermite-Hadamard type inequalities. We also present applications of our results to the Wright-convex functions with special emphasis on their key rol...

Symmetrization and Rademacher Complexity

Let’s first see how primitive covers were inadequate. Recall that a function class G is a primitive cover for a function class F at scale > 0 over some set S if: • G ⊆ F , • |G| <∞, and • for every f ∈ F there exists g ∈ G with supx∈S |g(x)− f(x)| ≤ . Last class, we gave a generalization bound for classes with primitive covers (basically, primitive covers give discretizations, and then we apply...

Symmetrizing The Symmetrization Postulate

Reasonable requirements of (a) physical invariance under particle permutation and (b) physical completeness of state descriptions [1], enable us to deduce a Symmetric Permutation Rule(SPR): that by taking care with our state descriptions, it is always possible to construct state vectors (or wave functions) that are purely symmetric under pure permutation for all particles, regardless of type di...
