From Semiconducting Engineering, September 12, 2022: How do you extend the lifespan of qubits? Researchers at the Supercomputing Quantum Materials and Systems Center say silicon limits the lifespan of qubits because of quantum decoherence. Fermilab’s Alexander Romanenko discusses recently published research on how individual sub-components contribute to the decoherence of the qubits. Could sapphire be a better choice for future quantum chips?

Scientists at the SQMS Center have directly probed silicon’s impact on the lifespan of superconducting qubits. The uniquely sensitive measurement helped researchers quantify how the material impacts qubit performance.

From the Polsky Center, July 26, 2022: Fermilab’s quantum ASIC group leader Shaorui Li founded Lismikro, a new start-up dedicated to developing innovative low-power microchip controllers to solve the hardware bottleneck and unleash the full potential of quantum computers. Lismikro was awarded a $200,000 co-investment from the Polsky Center’s George Shultz Innovation Fund and is capable of scaling the control electronics beyond today’s 100 qubits for superconducting, ion trap, and photonic quantum processors.

From Quantum Computing Report, April 30, 2022: A Fermilab quantum engineering team has collaborated with the University of Chicago to create a new open-source design for control electronics for superconducting quantum processors called the Quantum Instrumentation Control Kit.

Quantum computing experiments now have a new control and readout electronics option that will significantly improve performance while replacing cumbersome and expensive systems. Developed by a team of engineers at Fermilab in collaboration with the University of Chicago, the Quantum Instrumentation Control Kit, or QICK for short, is easily scalable.

Scientists at the Fermilab-led SQMS Center investigate qubits at the atomic level to identify sources of various impurities. By having a deeper understanding of how impurities affect how long a qubit can store information, scientists will be able to figure out how to further improve the performance of quantum computers.

As we step into the quantum age, here are four things to know about quantum networks.

Scientists are exploring a variety of ways to make quantum bits. We may not need to settle on a single one.

Quantum computers go beyond the binary.

Scientists at the Fermilab-led Superconducting Quantum Materials and Systems Center have discovered that nanohydrides, variants of an imperfection found in advanced superconducting materials for particle accelerators, also affect industrially produced superconducting qubits.
