Toffoli Gate
A three-qubit controlled gate that flips the target qubit if and only if both control qubits are 1. It is a core building block for constructing universal reversible logic and is analogous to the NAND gate in classical computing.
Timeline (last 90 days)
The Toffoli gate is a three-qubit controlled gate that flips the target qubit if and only if both control qubits are 1.
In quantum computing, the physical implementation of the Toffoli gate usually requires decomposition into multiple elementary gates (such as CNOT and single-qubit gates), and the number of gates after decomposition and the circuit depth directly determine the error rate.
Among the eight tasks, seven simultaneously significantly reduced the number of Toffoli gates and the number of qubits, with both key resource metrics outperforming the previous state of the art.
In fault-tolerant quantum computing, Toffoli gates often involve expensive magic state distillation processes, and their count is the primary metric for assessing the feasibility of an algorithm.
