Join us for Quantum Today, where we sit down with researchers from the University of Waterloo’s Institute for Quantum Computing (IQC) to talk about their work, its impact and where their research may lead.

Researchers from the QuantumION project at IQC are building an accessible platform for quantum computing using trapped ions as qubits. Controlling the state of these ions requires carefully calibrated laser systems, and technical noise from these lasers limits our ability to control the quits and perform computational tasks. In this instalment of Quantum Today, Transformative Quantum Technologies Research Associate Matthew Day joins IQC’s Dr. John Donohue to discuss their recent result which finds new ways to characterize laser noise and improve qubit control to the fundamental limits.

Find their publication, titled “Limits on atomic qubit control from laser noise” in npj Quantum Information.
