Experimental Saturation of the Heat-Bath Algorithmic Cooling bound
Sebastian Zaiser, Billy Masatth, D. D. Bhaktavatsala Rao +2
Heat-Bath Algorithmic cooling (HBAC) techniques provide ways to selectively enhance the polarization of target quantum subsystems. However, the cooling in these techniques are boun…
Non-classical measurement statistics induced by a coherent spin environment
D. D. Bhaktavatsala Rao, Sen Yang, Stefan Jesenski +2
We demonstrate the role of measurement back-action of a coherent spin environment on the dynamics of a spin (qubit) coupled to it, by inducing non-classical (Quantum Random Walk li…
Dissipative entanglement of solid-state spins in diamond
D. D. Bhaktavatsala Rao, Sen Yang, Jörg Wrachtrup
Generating robust entanglement among solid-state spins is key for applications in quantum information processing and precision sensing. We show here a dissipative approach to gener…
Heralded Control of Mechanical motion by Single Spins
D. D. Bhaktavatsala Rao, S. Ali Momenzadeh, Jörg Wrachtrup
We propose a method to achieve high degree control of nanomechanical oscillators by coupling their mechanical motion to single spins. By manipulating the spin alone and measuring i…
Generation of entangled photon strings using NV centers in diamond
D. D. Bhaktavatsala Rao, Sen Yang, Jörg Wrachtrup
We present a scheme to generate entangled photons using the NV centers in diamond. We show how the long-lived nuclear spin in diamond can mediate entanglement between multiple phot…
Filtering single atoms from Rydberg blockaded mesoscopic ensembles
David Petrosyan, D. D. Bhaktavatsala Rao, Klaus Mølmer
We propose an efficient method to filter out single atoms from trapped ensembles with unknown number of atoms. The method employs stimulated adiabatic passage to reversibly transfe…
