Perspectives of microwave quantum key distribution in the open air

2023 · Physical Review A

One of the cornerstones of quantum communication is the unconditionally secure distribution of classical keys between remote parties. This key feature of quantum technology is based on the quantum properties of propagating electromagnetic waves, such …

Single-shot readout of a superconducting qubit using a thermal detector

2024 · Nature Electronics

Abstract Measuring the state of a qubit is a key fundamental operation of a quantum computer. High-fidelity single-shot readout of superconducting qubits can be achieved using parametric amplifiers at millikelvin temperatures. However, scaling parametric amplifiers …
