我们提出并讨论了基于量子通量锁存器(QFL)的绝热量子通量参量管(AQFP)逻辑电路。基于 QFL 的异或 (QXOR) 门是一种新颖的异或门。 QXOR 的电路原理图与 QFL 的电路原理图相同,但由于交流偏置,QXOR 的工作原理不同。我们设计并制造了 QXOR 和包括 QXOR 的半加器。我们在低速功能测试中成功演示了这些电路在 4.2 K 下的正确逻辑运算。此外,我们还使用电路模拟器估算了 QFL 的能量耗散。估计能量耗散为0.2 aJ/周期。
We propose and discuss quantum-flux-latch (QFL) based circuits for adiabatic quantum-flux-parametron (AQFP) logic. The QFL-based XOR (QXOR) gate is a novel XOR gate. The circuit schematic of the QXOR is the same as that of a QFL, but QXORs operate on a different operation principle due to ac biasing. We designed and fabricated the QXOR and the half adder including a QXOR. We successfully demonstrated correct logic operations of these circuits at 4.2 K in the low-speed function test. Also, we estimated the energy dissipation of the QFL using a circuit simulator. The estimated energy dissipation was0.2 aJ/cycle.
