摘要：this paper concept of Quantum-dot Controlled-NOT (QCNOT) gate has been introduced. The orbitalstates of electron wavefunction have been used for simulation of Controlled-NOT (CNOT) gate introduced here.Asymmetric coupled QDs (QDs of different size) fabricated from InAs dots on GaAs substrate have been considered.The outcomes obtained from the simulation were advocating realization of CNOT gate. The predominant parameter forthe implementation of CNOT gate is Quantum tunneling. Therefore, the prime element to be controlled is interdotseparation. The consequence of QD separation for desirable coupling had been employed. Controlled-Controlled NOT(CCN) gate (also known as Toffloi gate) having two control and one target qubit which is continuation of CNOT gate,is also studied. By using CCN gate it is possible to realize universal gate analogous to classical CMOS/TTL whichgives the truth table equivalent to NAND gate at certain condition.
