Cryogenic Hardware Considerations Of Neural Network Decoders For Quantum Error Correction Using Rotated Surface Codes

The quantum bits (qubits) at the core of any quantum computers are so fragile that quantum error correction(QEC) schemes are needed to increase their robustness and enable fault-tolerant quantum algorithms. The surface code is one of the most popular QEC schemes, but it requires the availability of an efficient decoder. While neural networks...

A 1 GSa/s Deep Cryogenic, Reconfigurable Soft-core FPGA ADC for Quantum Computing Applications

Analog interfacing is the only way to communicate with a quantum processor, whether it is applying qubit operations or reading their quantum states. There exist other applications where analog interfacing is abundant, e.g. sensor networks, automotive, industrial control, etc. In those applications the use of FPGAs is continuously growing,...
