Kondo effect and Josephson current through a quantum dot between two superconductors
We investigate the supercurrent through a quantum dot for the whole range of couplings using the numerical renormalization group method. We find that the Josephson current switches abruptly from a pto a 0-phase as the coupling increases. At intermediate couplings the total spin in the ground state depends on the phase difference between the two superconductors. Our numerical results can explain...
متن کاملVoltage-Controlled Entanglement between Quantum- Dot Molecule and its Spontaneous Emission Fields via Quantum Entropy
The time evolution of the quantum entropy in a coherently driven threelevel quantum dot (QD) molecule is investigated. The entanglement of quantum dot molecule and its spontaneous emission field is coherently controlled by the gat voltage and the intensity of applied field. It is shown that the degree of entanglement between a three-level quantum dot molecule and its spontaneous emission fields...
متن کاملUltrafast optical control of entanglement between two quantum-dot spins
The interaction between two quantum bits enables the creation of entanglement, the two-particle correlations that are at the heart of quantum information science. In semiconductor quantum dots, much work has focused on demonstrating control over single spin qubits using optical techniques. However, optical control of two spin qubits remains a major challenge for scaling to a fully fledged quant...
متن کاملJosephson versus Kondo coupling in a Quantum Dot Connected to Two Superconductors
We apply a Gutzwiller-like variational technique to study Josephson conduction across a quantum dot with an odd number of electrons connected to two superconducting leads. Our method projects out all states on the dot but the Kondo singlet and is valid when Kondo correlations are dominant and no Andreev bound states localized at the dot are available for Kondo screening. In these conditions sup...
متن کاملQuantum gates between two spins in a triple-dot system with an empty dot
We propose a scheme for implementing quantum gates and entanglement between spin qubits in the outer dots of a triple-dot system with an empty central dot. The voltage applied to the central dot can be tuned to realize the gate. Our scheme exemplifies the possibility of quantum gates outside the regime where each dot has an electron, so that spin-spin exchange interaction is not the only releva...
