Efficient Universal Quantum Circuits
... circuits exist for the gate families F = {H, T } ∪ {Fn | n ≥ 1} and F 0 = {H, T } ∪ {Fn | n ≥ 1} ∪ {∧n (X) | n ≥ 1}, where H and T are the Hadamard and π/8 gates, respectively, and Fn and ∧n (X) are the (n + 1)-qubit fanout and (n + 1)qubit Toffoli gates, respectively (see Sect. 2). In order to cons ...

... 2.2. “Toy quadratic noises”. The formula for Ẑ or for Ẑ + has one interesting feature: it involves a perturbation that is localized just at τ = 0. One can ask whether one can consider other dilations with more general perturbations localized at τ = 0. In this subsection we will describe such dilat ...

Strong no-go theorem for Gaussian quantum bit commitment
... because of their associated detection scheme, namely, homodyne detection. This is well illustrated with CV quantum key distribution, which was recently proven unconditionally secure [15] and appears as a credible alternative to singlephoton-based quantum key distribution [16]. Dealing with CV quantu ...
