Implementation of the Toffoli gate with only single- and two-qubit operations requires six controlled-NOT gates and 10 single-qubit operations. As a result, a single-step Toffoli gate can reduce ...

Making two photons "talk" to each other to realise the all-important controlled-NOT gate is much harder, but Dr O'Brien and his colleagues at the University of Queensland demonstrated this back in ...

The team developed 'the world's smallest optical controlled-NOT gate -- the building block of a quantum computer.' As said the lead researcher, 'This is a crucial step towards a future optical ...

controlled-phase gates, and controlled-not gates. The review focuses on two main types of silicon spin qubits: gate-defined quantum dots and donor-based quantum dots. Gate-defined quantum dots are ...

However, once you have these two elements, you can make a controlled NOT gate—a gate that inverts the quantum state of one qubit, depending on the state of the controlling qubit—which is a ...

the research group then tested the 2-bits CNOT gate (Control-not gate) and the 3-bits Toffoli gate (Controlled-controlled-not gate), and obtained an average 1600 and 2600 times of measurements ...

Dr Jeremy O’Brien, his PhD student Alberto Politi, and their colleagues at Bristol University have demonstrated the world’s smallest optical controlled-NOT gate – the building block of a ...
