Browser-based converter for energy, frequency, temperature, and magnetic-field scales in superconducting devices, with charging-energy, Josephson-energy, and transmon estimates.
Stand-alone random number generator combining quantum and oscillator-based entropy sources, with Ethernet connectivity for delivering random data.
Its three sources are a quantum source based on a beam splitter and light emission just above threshold, a ring oscillator in a differential configuration, and a fast self-timed ring oscillator. It uses Toeplitz randomness extraction and SHA-256 cryptographic hash extraction.
Open-source FPGA pulse sequencer for laboratory timing and digital control, providing programmable digital outputs for pulse sequences, triggers, multiplexing, and instrument synchronization.
