Qubit encodings in the p-orbital-valley spectrum for enhanced coherence and tunable two-qubit interaction
John H. Caporaletti, J. P. Kestner
We propose encoding a qubit in a two-level subspace spanned by the lowest -orbital state in the excited valley of an anisotropic quantum dot and the excited -orbital in the g…

Proposed Five-Electron Charge Quadrupole Qubit
John H. Caporaletti, J. P. Kestner
A charge qubit couples to environmental electric field fluctuations through its dipole moment, resulting in fast decoherence. We propose the p orbital (pO) qubit, formed by the sin…
