Efficient Implementation of a Quantum Algorithm in a Single Nitrogen Vacancy Center of Diamond
Jingfu Zhang, Swathi S. Hegde, Dieter Suter
Quantum computers have the potential to speed up certain problems that are hard for classical computers. Hybrid systems, such as the nitrogen vacancy (NV) center in diamond, are am…
Efficient quantum gates for individual nuclear spin qubits by indirect control
Swathi S. Hegde, Jingfu Zhang, Dieter Suter
Hybrid quantum registers, such as electron-nuclear spin systems, have emerged as promising hardware for implementing quantum information and computing protocols in scalable systems…
Improved indirect control of nuclear spins in diamond NV centers
Jingfu Zhang, Swathi S. Hegde, Dieter Suter
Hybrid quantum registers consisting of different types of qubits offer a range of advantages as well as challenges. The main challenge is that some types of qubits react only slowl…
Pulse sequences for controlled 2- and 3-qubit gates in a hybrid quantum register
Jingfu Zhang, Swathi S Hegde, Dieter Suter
We propose and demonstrate a quantum control scheme for hybrid quantum registers that can reduce the operation time, and therefore the effects of relaxation, compared to existing i…
Pauli Decomposition over Commuting Subsets: Applications in Gate Synthesis, State Preparation, and Quantum Simulations
Swathi S. Hegde, K. R. Koteswara Rao, T. S. Mahesh
A key task in quantum computation is the application of a sequence of gates implementing a specific unitary operation. However, the decomposition of an arbitrary unitary operation…
