Tested on temperatures as low as 4K, Intel's new 22nm Horse Ridge II SoC not only allows the manipulation of qubit states but also the control of gate potentials to entangle qubits.
Horse Ridge, developed using Intel's 22nm FinFET technology, is a cryogenic, highly-integrated, mixed-signal SoC that will facilitate more efficient control of multiple qubits in a quantum computer.
