T深度的量子线路

Quantum circuits of T-depth one

Peter Selinger

摘要:

我们给出了T-depth为1的Toffoli门的Clifford+T表示,使用四个Ancilla。更一般地说,我们描述了一类电路的T-深度可以减少到1,通过使用足够多的辅助。我们表明,增加一个额外的控制到任何受控门的成本是最多8个额外的T-门,和T-深度2。我们还表明,电路THT不具有T-深度1表示与任意数量的ancillas初始化为0。

英文摘要:

We give a Clifford+T representation of the Toffoli gate of T-depth 1, using four ancillas. More generally, we describe a class of circuits whose T-depth can be reduced to 1 by using sufficiently many ancillas. We show that the cost of adding an additional control to any controlled gate is at most 8 additional T-gates, and T-depth 2. We also show that the circuit THT does not possess a T-depth 1 representation with an arbitrary number of ancillas initialized to 0.
