Implementation of the Toffoli gate with only single- and two-qubit gates requires six controlled-NOT gates and ten single-qubit operations, and has not been realized in any system owing to current ...

As a result, a single-step Toffoli gate can reduce the number of quantum operations dramatically, which can break the limit of coherence time and improve the efficiency of quantum computing.

The new gate family includes the N-qubit Toffoli gate, which flips a select qubit if and only if all the other qubits are in a particular state. Unlike standard two-qubit quantum computing gates ...

Unlike standard two-qubit quantum computing gates, the N-qubit Toffoli gate acts on many qubits at once, leading to more efficient operations.

The San Jose Sharks face the Vancouver Canucks Monday night in their final road game of a challenging season.

The experiment demonstrated, similarly to the Toffoli gate, this three-qubit iToffoli gate can be used to perform universal quantum computation with high fidelity.

The Toffoli or the controlled-controlled-NOT (CCNOT) is a key logical gate in classical computing because it is universal, so it can build all logic circuits to compute any desired binary operation.

For example, the Toffoli gate 2 acts on three bits: it checks whether the first two are both equal to 1 and, if this is the case, alters the value of the third.

The New Jersey Devils have traded veteran forward Tyler Toffoli to the Winnipeg Jets in exchange for a 2025 second-round pick and a third-round pick in 2024, the teams announced Friday ...
