Duke University and IonQ Develop New Quantum Computing Gate – HPCwire

DURHAM, N.C. & COLLEGE PARK, Md., Feb. 10, 2022 Today, the Duke Quantum Center (DQC) at Duke University and IonQ announced the invention of a new quantum computing operation with the potential to accelerate several key quantum computing techniques and contribute to scaling quantum algorithms. The new quantum gate is a novel way to operate on many connected qubits at once and leverages the multi-qubit communication bus available only on IonQ and DQC quantum computers. Full details of the gate technique can be found on the preprint archive arXiv at arXiv:2202.04230.

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, the N-qubit Toffoli gate acts on many qubits at once, leading to more efficient operations. The gate appears naturally in many common quantum algorithms.

IonQ and Dukes discovery may lead to significant efficiency gains in solving fundamental quantum algorithms, such as Grovers search algorithm, variational quantum eigensolvers (VQEs), and arithmetic operations like addition and multiplication. These use cases are ubiquitous across quantum computing applications, and are core to IonQs 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 alreadyshown IonQs computers to be industry leaders.

This discovery is an example of us continuing to build on the leading technical architecture weve established. It adds to the unique and powerful capabilities we are developing for quantum computing applications, said Peter Chapman, CEO at IonQ.

This research, conducted at Duke by Dr. Or Katz, Prof. Marko Cetina, and IonQ co-Founder and Chief Scientist Prof. Christopher Monroe, will be integrated into IonQs quantum computing operating system for the general public to use. Monroe notes that, no other available quantum computing architecturesnot even other ion-based quantum computersare able to utilize this new family of N-qubit gates. This is because IonQs quantum computers uniquely feature full connectivity and a wide communication bus that allows all qubits to talk to each other simultaneously.

This discovery follows a series of announcements around IonQs research efforts and preparations for scale. In December, IonQ announced that itplans to use barium ions as qubitsin its systems, bringing about a wave of advantages it believes will enable advanced quantum computing architectures. Last year, the team also debuted the industrys firstReconfigurable Multicore Quantum Architecture and Evaporated Glass Trap technology, both of which are expected to contribute to scaling the number of qubits in IonQs quantum computers.
