摘要:
Quantum computing requires a set of universal quantum gates. The standard set includes single quantum bit (qubit) gates and the controlled-NOT (CNOT) which is the analog of the classical XOR gate. It flips the state of the target qubit conditioned on the state of the control qubit. We investigated the possibility of implementing a CNOT logic gate using magnetically coupled impurity spins of diamond, namely the electron spin-1 carried by the nitrogen-vacancy color center and the electron spin-1/2 carried by a nearby nitrogen atom in substitutional position (P1 center). It is shown that a 96 ns gate time with a high-fidelity can be realized by means of pulsed electron spin resonance spectroscopy. (C) 2014 Elsevier Ltd. All rights reserved
