用于基于测量的量子超前进位加法器的资源

Resources for Measurement-Based Quantum Carry-Lookahead Adder

Agung Trisetyarso, Rodney Van Meter, Kohei M. Itoh

摘要:

我们提出了一个基于测量的量子计算的量子超前进位加法器的设计。QCLA利用MBQC在单位时间内转移量子态的能力来加速加法。量子超前进位加法器(QCLA)比量子纹波进位加法器更快; QCLA具有对数深度,而纹波加法器具有线性深度。当添加长于100量子位的寄存器时,QCLA比纹波进位加法器快一个数量级,但需要更大一个数量级的簇状态。手动优化导致电路的空间资源减少$\approx$ 26%。

英文摘要:

We present the design of a quantum carry-lookahead adder using measurement-based quantum computation. QCLA utilizes MBQC`s ability to transfer quantum states in unit time to accelerate addition. The quantum carry-lookahead adder (QCLA) is faster than a quantum ripple-carry adder; QCLA has logarithmic depth while ripple adders have linear depth. QCLA is an order of magnitude faster than a ripple-carry adder when adding registers longer than 100 qubits but requires a cluster state that is an order of magnitude larger. Hand optimization results in a $\approx$ 26% reduction in spatial resources for the circuit.
