Pulse-Gated Quantum-Dot Hybrid Qubit
Pulse-Gated Quantum-Dot Hybrid Qubit
A quantum-dot hybrid qubit formed from three electrons in a double quantum dot has the potential for great speed, due to the presence of level crossings where the qubit becomes chargelike. Here, we show how to exploit the level crossings to implement fast pulsed gating. We develop one- and two-qubit …
