DURHAM- Duke University‘s Duke Quantum Center (DQC) and IonQ (NYSE: IONQ) have announced the invention of a new quantum computing operation with the potential to accelerate several key quantum computing techniques and help at the scale of quantum algorithms. The new quantum gate is a new way to operate on many qubits connected at once and leverages the multi-qubit communication bus available only on IonQ and DQC quantum computers.

Full door tech details can be found on the arXiv preprint archive at arXiv:2202.04230.

The new family of gates includes the N-qubit Toffoli gate, which flips a selected qubit if and only if all other qubits are in a particular state. Unlike standard two-qubit quantum computing gates, the N-qubit Toffoli gate operates on multiple qubits at once, allowing for more efficient operations. The gate appears naturally in many common quantum algorithms.

The discovery of IonQ and Duke can lead to significant efficiencies in solving fundamental quantum algorithms, such as Grover’s search algorithm, variational quantum eigensolvers (VQE), and arithmetic operations such as l addition and multiplication. These use cases are ubiquitous in quantum computing applications and are central to IonQ’s work in quantum chemistry, quantum finance, and quantum machine learning. They are also key components of commonly accepted industry benchmarks for quantum computers, which have already showed that IonQ’s computers were clearly industry leaders.

“This discovery is an example of our continued development on the state-of-the-art technical architecture that we have established. This adds to the unique and powerful capabilities we are developing for quantum computing applications,” said Peter Chapman, CEO of IonQ.

This research, led at Duke by Dr. Or Katz, Professor Marko Cetina, and IonQ co-founder and chief scientist, Professor Christopher Monroe, will be integrated into the IonQ quantum computing operating system for the large public can use it. Monroe notes that “no other available quantum computing architecture, not even other ion-based quantum computers, is capable of using this new family of N-qubit gates. Indeed, IonQ’s quantum computers uniquely feature full connectivity and a large communication bus that allows all qubits to talk to each other simultaneously.

This discovery follows a series of announcements regarding IonQ’s research efforts and large-scale preparations. In December, IonQ announced that it plans to use barium ions as qubits into its systems, bringing a wave of benefits that it believes will enable advanced quantum computing architectures. Last year, the team also launched the first Reconfigurable multi-core quantum architecture and evaporated glass trap technologyboth of which should help increase the number of qubits in IonQ’s quantum computers.

IonQ, Inc. is a leader in quantum computing, with a proven track record in innovation and deployment. IonQ’s next-generation quantum computer is the most powerful trapped-ion quantum computer in the world, and IonQ has defined what it believes is the best way forward to evolve.

IonQ is the only company whose quantum systems are available through the cloud on Amazon Braket, Microsoft Azure, and Google Cloud, as well as through direct API access. IonQ was founded in 2015 by Christopher Monroe and Jungsang Kim based on 25 years of pioneering research. To learn more, visit www.ionq.com.
