The electronic interface for quantum processors

Quantum computers can potentially provide an unprecedented speed-up with respect to traditional computers. However, a significant increase in the number of quantum bits (qubits) and their performance is required to demonstrate such quantum supremacy. While scaling up the underlying quantum processor is extremely challenging, building the...

Cryogenic CMOS supply voltage regulator for quantum computing applications

Quantum computers are able to deal with large problems, like molecular modelling, financial prediction and cryptography. A classical controller is used to control the qubits of the quantum computer. A proposed controller, operating at 4K, needs a clean voltage supply in order to function well. The long interconnects between the room temperature...

A Wide Temperature Range Voltage Reference for Quantum Computing Applications

Quantum computers seem very promising in solving problems that are too large to be solved by classical computers that are available today. However, to generate reasonable amounts of computing power, many qubits will be required. Each of the qubits has to be individually controlled and needs to be kept at cryogenic temperatures. To allow for the...

A Low-Power Standard Cell Library for Cryogenic Operation

With the advances towards a quantum computer incorporating many qubits, the demand for a scalable readout and control platform rises. Recent proposals for such a platform exploit the maturity of CMOS technology, to implement the various analog, RF and digital circuits required. To allow for scaling, the electronics that constitute this platform...
