IonQ (NYSE: IONQ), a world-leading quantum invention company known for its trapped-ion quantum computer, together with the Duke Quantum Center (DQC) at Duke University has announced their latest invention on the new method of performing the N-qubit Toffoli gate, a quantum gate that will accelerate a number of fundamental algorithms which can only be run through IonQ’s quantum computing operating system.
The new quantum gate uses the multi-qubit communication bus, which is only available on IonQ and DQC quantum computers, to operate on a large number of connected qubits at once. The development of the novel quantum computing technology has the potential to speed several quantum computing techniques and help scale quantum algorithms.
The N-qubit Toffoli gate flips a single qubit if and only if all the other qubits are in the same state. Unlike ordinary two-qubit quantum computing gates, works on a large number of qubits at once, making operations more efficient. Usually, the gate is considered a natural feature.
This discovery is an example of us continuing to build on the leading technical architecture we’ve established. It adds to the unique and powerful capabilities we are developing for quantum computing applications.
Peter Chapman, CEO at IonQ.
IonQ’s research activities and scale-up plans have been the subject of a succession of announcements. As a result, IonQ stated the use of barium ions as qubits in their system, which is assumed to enable a sophisticated quantum computing design.
No other available quantum computing architectures—not even other ion-based quantum computers—are able to utilize this new family of N-qubit gates. This is because IonQ’s quantum computers uniquely feature full connectivity and a wide communication bus that allows all qubits to talk to each other simultaneously.
