The HRL Lab in Malibu, California is another group working to create qubits using quantum dot (also known as spin qubit) technology. They have developed a 6 quantum dot, 2 qubit prototype device which they call SLEDGE. Together with Intel and MIT Lincoln Laboratories, they participate in Qubit for Computing Foundry (QCF) a program run by the LPS Qubit Collaboratory (LQC) that aims to provide academic and government researchers with high-quality qubit devices to help them advance their research.
The first devices that HRL ships will be sent to UCLA and the University of Wisconsin, as well as to LQC. Additional groups are expected to receive chips as the program expands in the future. HRL technology has a lot of flexibility and will allow changes in dimensions, materials and more. In the future, they will be able to provide their collaborators with customized versions of these chips. Among other unique features, the HRL design supports a function they call Partial Swap which allows the application of universal quantum control while reducing the source of microwave-associated correlated errors and providing low crosstalk characteristics that can be very useful for investigative error correction techniques.
