Fast quantum algorithm for numerical gradient estimation.
Given a black box for f, a smooth real scalar function of d real variables, one wants to estimate [symbol: see text]f at a given point with n bits of precision. On a classical computer this requires a minimum of d + 1 black box queries, whereas on a quantum computer it requires only one query regardless of d. The number of bits of precision to which f must be evaluated matches the classical req...
متن کاملHigh precision quantum control of single donor spins in silicon.
The Stark shift of the hyperfine coupling constant is investigated for a P donor in Si far below the ionization regime in the presence of interfaces using tight-binding and band minima basis approaches and compared to the recent precision measurements. In contrast with previous effective mass-based results, the quadratic Stark coefficient obtained from both theories agrees closely with the expe...
متن کاملA high precision algorithm for axisymmetric flow
We present a new algorithm for highly accurate computation of axisymmetric potential flow. The principal feature of the algorithm is the use of orthogonal curvilinear coordinates. These coordinates are used to write down the equations and to specify quadrilateral elements following the boundary. In particular, boundary conditions for the Stokes’ stream-function are satisfied exactly. The veloci...
متن کاملVariable Frequency Control for Spider-driven Ultra-precision Stages
This paper proposes a variable control method of drive frequency for the SPIDER-driven precision stage. Control performances such as positioning accuracy and maximum velocity strongly depend on the drive frequency. At first, the identification experiments of the SPIDER with different drive frequency are carried out. Next the gain-scheduled control strategy for the variable frequency control, co...
متن کاملA new hybrid conjugate gradient algorithm for unconstrained optimization
In this paper, a new hybrid conjugate gradient algorithm is proposed for solving unconstrained optimization problems. This new method can generate sufficient descent directions unrelated to any line search. Moreover, the global convergence of the proposed method is proved under the Wolfe line search. Numerical experiments are also presented to show the efficiency of the proposed algorithm, espe...
