Chiral-Induced Spin Selectivity Regulates Triplet formation in Heliobacterial Photosynthesis
Parul Raghuvanshi, Vishvendra Singh Poonia
Triplet formation and its regulation have always been of central interest in understanding the photophysical behavior of living systems. In organic systems, excessive triplet forma…
Dzyaloshinskii-Moriya interaction as a coherence diagnostic for chirality-induced spin selectivity
Vishvendra S. Poonia
Whether chirality-induced spin selectivity (CISS) reflects coherent SU(2) spin rotation or incoherent spin-dependent filtering is a central unresolved question in molecular spintro…
Quantum-Accelerated Gowers Norm for Bent Boolean Functions
Rajdeep Dwivedi, C. A. Jothiwashran, Sugata Gangopadhyay +1
Bent Boolean functions extremal objects that maximally resist affine approximation are notoriously hard to construct for large numbers of variables. We propose a hybrid quantum-cla…
Exchange-Only Silicon Based Spin Qubits: Charge Noise, PINN Optimised Pulse Sequences,and Gate-Level Fidelity
Rajdeep Rameshchandra Dwivedi, Amitoj Singh Miglani, Vishvendra Singh Poonia
Exchange-only (EO) spin qubits in silicon realise all-electrical qubit control through pairwise Heisenberg exchange interactions, making them attractive for scalable quantum comput…
Quantum-enhanced photocell based on GaN quantum dots
Aditya Dev, Sumit Chaudhary, Jay Reshamiya +2
In this work, we propose an efficient quantum-enhanced solid-state photocell based on GaN quantum dots. We exploit the strong built-in electric field in GaN QDs and excitonic dipol…
Quantum dot-based high-fidelity universal quantum gates in noisy environment
Yash Tiwari, Aditya Dev, Vishvendra Singh Poonia
Quantum dot-based spin qubit realization is one of the most promising quantum computing systems owing to its integrability with classical computation hardware and its versatility i…
