设计并分析了求解有限域({mathbf {F}} q)上m个n元二次方程组的量子算法。在(m=n)和(q=2)的情况下,在标准假设下,该算法在面积为(2^{(a+o(1))n})的网格连接计算机上花费时间(2 ^{(t+o(1))n}),其中(tapprox 0.45743)和(aapprox 0.01467)。面积-时间乘积具有渐近指数(t+ aapprox0.47210)。
This paper designs and analyzes a quantum algorithm to solve a system of m quadratic equations in n variables over a finite field ({mathbf {F}}_q). In the case (m=n) and (q=2), under standard assumptions, the algorithm takes time (2^{(t+o(1))n}) on a mesh-connected computer of area (2^{(a+o(1))n}), where (tapprox 0.45743) and (aapprox 0.01467). The area-time product has asymptotic exponent (t+aapprox 0.47210).
