Persistence of Entangled States and High Fidelity Quantum Gate Operations in Si/SiGe Spin Qubits at High Temperature
The episode discusses a paper on Si/SiGe spin qubits maintaining high fidelity and entangled states up to seven hundred fifty mK. Hosts discuss how this persistence, even with noise, suggests a viable operating temperature for integrated cryogenic electronics. Key takeaways include the need for fabrication improvements to reduce charge noise and the importance of better readout sensors.
