Fast On-Chip Thermometry with TiN Kinetic Inductance Resonators in 22 nm Process Technology
Johann Drayne, George Ridgard, Lorenzo Peri +9
Understanding the temporal and spatial dependence of temperature is critical in high-performance cryogenic devices. Typical thermometry techniques struggle to simultaneously combin…
A Superconducting Phase Transition Single-Electron Transistor
Gorka Aizpurua-Iraola, Thomas H. Swift, Felix-Ekkehard von Horstig +6
Quantum computers require fast and accurate methods for qubit state detection. Phase-transition sensors exploit the abrupt change between two physical states of a material to achie…
Stream Decoding with Confidence Scores at Room and Cryogenic Temperatures
Maries Tahaab, Tim Chan, James Kirkman +1
In fault-tolerant quantum computing, fast and accurate decoding is crucial. Snowflake is a decoder for the surface code that runs in a streaming fashion. In this paper, we implemen…
A superinductor in a deep sub-micron integrated circuit
T. H. Swift, F. Olivieri, G. Aizpurua-Iraola +7
Superinductors are circuit elements characterised by an intrinsic impedance in excess of the superconducting resistance quantum (k), with applications fr…
A Multi-Module Silicon-On-Insulator Chip Assembly Containing Quantum Dots and Cryogenic Radio-Frequency Readout Electronics
David J. Ibberson, James Kirkman, John J. L. Morton +2
Quantum processing units will be modules of larger information processing systems containing also digital and analog electronics modules. Silicon-based quantum computing offers the…
