Researchers at NIST and the University of Colorado Boulder have developed a new testing facility called the Boulder Cryogenic Quantum Testbed. This facility allows them to accurately measure and compare the performance of different types of superconducting qubits used in quantum computers.
The testbed is unique because it can account for many of the performance variations seen in superconducting qubits, such as those caused by small changes in experimental setup and data analysis. By carefully measuring and analyzing the data from qubits made from different materials like niobium, aluminum, and gallium arsenide, researchers can determine which types of qubits perform better and why.
The Boulder Cryogenic Quantum Testbed is expected to lead to the development of high-performance superconducting qubits and eventually a full-scale quantum computer with the power to revolutionize our ability to solve hard problems in chemistry, cryptography, and quantum mechanics.
The testbed is a highly collaborative laboratory with a one-of-a-kind experimental setup for accurate measurement of superconducting quantum circuits. It was founded by Corey Rae McRae, a postdoctoral associate in the Quantum Processing Group at NIST Boulder, and David Pappas, leader of the Quantum Processing Group at NIST, along with Josh Mutus, a research scientist at Google.
