NMR implementation of Quantum Delayed-Choice Experiment
Soumya Singha Roy, Abhishek Shukla, T. S. Mahesh
We report the first experimental demonstration of quantum delayed-choice experiment via nuclear magnetic resonance techniques. An ensemble of molecules each with two spin-1/2 nucle…
Study of Electromagnetically Induced Transparency using long-lived Singlet States
Soumya Singha Roy, T. S. Mahesh
The long-lived singlet states are useful to study a variety of interesting quantum phenomena. In this work we study electromagnetically induced transparency using a two-qubit syste…
Storing entanglement of nuclear spins via Uhrig Dynamical Decoupling
Soumya Singha Roy, T. S. Mahesh, G. S. Agarwal
Stroboscopic spin flips have already been shown to prolong the coherence times of quantum systems under noisy environments. Uhrig's dynamical decoupling scheme provides an optimal…
