This study confirms bilayer graphene double quantum dots can sustain coherent charge oscillations with 400–500 ps coherence times, validating their viability as qubits. The consistent results across multiple measurement techniques highlight the material's potential for scalable spin and valley qubit architectures in future quantum processors.
500 ps Charge Coherence Achieved in Bilayer Graphene Quantum Dots
Coherent charge oscillations are observed in bilayer graphene quantum dots, showing potential as qubits.
Researchers have measured charge decoherence times between 400 and 500 picoseconds in bilayer graphene double quantum dots, a result achieved using both Landau-Zener-Stückelberg-Majorana (LZSM) interference and photon assisted tunneling. This consistency across different measurement methods suggests bilayer graphene is a promising material for developing…
