(author), Bruno, A. (author), Deurloo, D. (author), Schouten, R.N. (author), Wilhelm, FK (author), DiCarlo, L. (author)We present a tuneup protocol for qubit gates with tenfold speedup over traditional methods reliant on qubit initialization by energy relaxation. This speedup is achieved by constructing a cost function for Nelder-Mead optimization from real-time correlation of nondemolition measurements interleaving gate operations without pause. Applying the...journal article 2017

Bolt, RJ (author), Cavallo, D. (author), Gerini, G (author), Deurloo, D. (author), Grooters, G (author), Neto, A. (author), Toso, G (author)In this paper, we present the characterization of a Ku-band connected-dipole array for mobile Satcom application. The prototype array consists of 2×256 dipole radiators arranged in a square grid, to form 16×16 dual-polarized cells. It has been designed to operate over a wideband ranging from 10.7 to 14.5 GHz (30%), accommodating in a single...journal article 2016
