Successfully integrated qubit control in quantum computers

The biggest challenges in quantum computing currently lie behind the word scalability. The more quantum bits (qubits) the computing system has to bring together, the more electronic lines have to reach the core of the supercomputer, for example. At the same time, however, each electronic line conducts heat to a point in the quantum computer that should remain as cold as possible. Researchers at the TU Braunschweig have now developed a control chip that reaches more qubits with fewer wires and therefore less heat. The success of the new control unit is being utilised within the quantum computer of the Quantum Valley Lower Saxony (QVLS). The current results were recently published in the journal IEEE Transactions on Circuits and Systems Part II: Express Briefs.
