Fast Black-Box Quantum State Preparation Based on Linear Combination of Unitaries
Shengbin Wang, Zhimin Wang, Guolong Cui +6
Black-box quantum state preparation is a fundamental primitive in quantum algorithms. Starting from Grover, a series of techniques have been devised to reduce the complexity. In th…
Quantum Amplitude Arithmetic
Shengbin Wang, Zhimin Wang, Guolong Cui +6
Quantum algorithm involves the manipulation of amplitudes and computational basis, of which manipulating basis is largely a quantum analogue of classical computing that is always a…
Quantum Fast Poisson Solver: the algorithm and modular circuit design
Shengbin Wang, Zhimin Wang, Wendong Li +3
The Poisson equation has applications across many areas of physics and engineering, such as the dynamic process simulation of ocean current. Here we present a quantum Fast Poisson…
