Optical spin initialization of spin-3/2 silicon vacancy centers in 6H-SiC at room temperature
Harpreet Singh, Andrei N. Anisimov, I. D. Breev +2
Silicon vacancies in silicon carbide have been proposed as an alternative to nitrogen vacancy centers in diamonds for spintronics and quantum technologies. An important preconditio…
Experimental characterization of spin-3/2 silicon vacancy centers in 6H-SiC
Harpreet Singh, Andrei N. Anisimov, Sergei S. Nagalyuk +3
Silicon carbide (SiC) hosts many interesting defects that can potentially serve as qubits for a range of advanced quantum technologies. Some of them have very interesting propertie…
Experimental Classification of Entanglement in Arbitrary Three-Qubit States on an NMR Quantum Information Processor
Amandeep Singh, Harpreet Singh, Kavita Dorai +1
We undertake experimental detection of the entanglement present in arbitrary three-qubit pure quantum states on an NMR quantum information processor. Measurements of only four obse…
Generation, estimation, and protection of novel quantum states of spin systems
Harpreet Singh
This thesis deals with the generation, estimation and preservation of novel quantum states of two and three qubits, on an NMR quantum information processor. Using the maximum likel…
