Sensing of magnetic field effects in radical-pair reactions using a quantum sensor
Deepak Khurana, Rasmus H. Jensen, Rakshyakar Giri +4
Magnetic field effects (MFE) in certain chemical reactions have been well established in the last five decades and are attributed to the evolution of transient radical-pairs whose…
Charge stability and charge-state-based spin readout of shallow nitrogen-vacancy centers in diamond
Rakshyakar Giri, Rasmus H. Jensen, Deepak Khurana +8
Spin-based applications of the negatively charged nitrogen-vacancy (NV) center in diamonds require efficient spin readout. One approach is the spin-to-charge conversion (SCC), rely…
Star-topology Registers: NMR and Quantum Information Perspectives
T S Mahesh, Deepak Khurana, Krithika V R +2
Quantum control of large spin registers is crucial for many applications ranging from spectroscopy to quantum information. A key factor that determines the efficiency of a register…
Unambiguous measurement of information scrambling in a hierarchical star-topology system
Deepak Khurana, V. R. Krithika, T. S. Mahesh
We investigate the scrambling of information in a hierarchical star-topology system using out-of-time-ordered correlation (OTOC) functions. The system consists of a central qubit d…
Experimental emulation of quantum non-Markovian dynamics and coherence protection in the presence of information backflow
Deepak Khurana, Bijay Kumar Agarwalla, T. S. Mahesh
We experimentally emulate, in a controlled fashion, the non-Markovian dynamics of a pure dephasing spin-boson model at zero temperature. Specifically, we use a randomized set of ex…
Bang-Bang Optimal Control of Large Spin Systems: Enhancement of C-C Singlet-Order at Natural Abundance
Deepak Khurana, T. S. Mahesh
Using a Bang-Bang optimal control (BB) technique, we transfer polarization from abundant high- nuclei directly to singlet order. This approach is analogous to algorithmic coolin…
