Transmon qubit readout fidelity at the threshold for quantum error correction without a quantum-limited amplifier [PDF]
npj Quantum Information, 2022 High-fidelity and rapid readout of a qubit state is key to quantum computing and communication, and it is a prerequisite for quantum error correction. We present a readout scheme for superconducting qubits that combines two microwave techniques: applying
