Very Fast Quantum Calculations with Germanium Transistors | NextBigFuture.com

The researchers at QuTech, a collaboration of TU Delft and TNO, have built two germanium transistors that can be the building blocks for fast quantum computing. Before this work it was not possible to perform quantum calculations using only transistors. Other elements were needed and this provided a limitation for upscaling. This work shows a single transistor can function as a quantum bit by using germanium. Nature – Fast two-qubit logic with holes in germanium Abstract Universal quantum information processing requires the execution of single-qubit and two-qubit logic. Across all qubit realizations1, spin qubits in quantum dots have great promise
