Pyroelectric effects in hybrid semiconductor-lithium niobate quantum devices
Manas Ranjan Sahu, Suraj Thapa Magar, Yadav Prasad Kandel +1
Hybrid quantum devices using surface acoustic waves show promise as key elements of quantum information processors. We report measurements of integrated flip-chip devices consistin…
Mitigating Residual Exchange Coupling in Resonant Singlet-Triplet Qubits
Jiheng Duan, Fernando Torres-Leal, John M. Nichol
We propose methods to mitigate single- and two-qubit control errors due to residual exchange coupling in systems of exchange-coupled resonant singlet-triplet qubits. Commensurate d…
Measuring pulse heating in Si quantum dots with individual two-level fluctuators
Feiyang Ye, Lokendra S. Dhami, John M. Nichol
To encode quantum information in semiconductor spin qubits, voltage pulses are necessary for initialization, gate operation, and readout. However, these pulses dissipate heat, shif…
