Nonlocal Magnonic Cat States in Hybrid Magnon-Qubit Architectures
Urmimala Dewan, Roson Nongthombam, Sampreet Kalita +1
The quantum superpositions of coherent states offer an alternative to the conventional qubit-based encodings by harnessing the large Hilbert space available in bosonic modes, inclu…

Polarization entanglement and qubit error rate dependence on the exciton-phonon coupling in self-assembled quantum dots
Urmimala Dewan, Parvendra Kumar, Amarendra K. Sarma
Polarization-entangled photons are key resources for a wide range of protocols in quantum computation and quantum key distribution. Achieving a near-unity degree of polarization en…
