    "abstract": "A Toffoli gate ($C^{n}$-NOT gate) is regarded as an important unitary gate in\nquantum computation, and is simulated by a quantum circuit composed of\n$C^{2}$-NOT gates. This paper presents a quantum circuit with a new\nconfiguration of $C^{2}$-NOT gates simulating a $C^{2m+1}$-NOT operation under\nthe condition $m=2^{n}$ ($n=1,2,...$). The circuit is composed of units called\nmulti-qubits gates (MQGs), each of which performs $m$ $C^{2}$-NOT operations\nsimultaneously on $3m$ qubits. Simultaneous operations eliminate the need to\nmanipulate qubits individually, as required in conventional quantum circuits.\nThe proposed circuit thus represents a more realistic mode of operation for\npractical computing systems. A nuclear magnetic resonance implementation of the\ncircuit is presented as a demonstration of the feasibility of MQG operations\nfor practical systems.",
