چکیده
Using a powerful combination of Coleman’s instanton technique and the method of Banks and Bender, the exponential factor for the zero temperature tunneling rate out of metastable vacuum in the system of two identical capacitively coupled phase qubits is calculated in closed form to second order in asymmetry parameter for a special case of intermediate coupling C = CJ/2.

Tunneling out of metastable vacuum in a system consisting of two capacitively coupled phase qubits
Using a powerful combination of Coleman’s instanton technique and the method of Banks and Bender, the exponential factor for the zero temperature rate of tunneling out of metastable vacuum in a system of two identical capacitively coupled phase qubits is calculated in closed form to second order in asymmetry parameter for a special case of intermediate coupling C = CJ/2.
متن کاملSuper operator Technique in Investigation of the Dynamics of a Two Non-Interacting Qubit System Coupled to a Thermal Reservoir
In this paper, we clarify the applicability of the super operator technique for describing the dissipative quantum dynamics of a system consists of two qubits coupled with a thermal bath at finite temperature. By using super operator technique, we solve the master equation and find the matrix elements of the density operator. Considering the qubits to be initially prepared in a general mixed st...
متن کاملQuantum gates between capacitively coupled double quantum dot two-spin qubits
We study the two-qubit controlled-not gate operating on qubits encoded in the spin state of a pair of electrons in a double quantum dot. We assume that the electrons can tunnel between the two quantum dots encoding a single qubit, while tunneling between the quantum dots that belong to different qubits is forbidden. Therefore, the two qubits interact exclusively through the direct Coulomb repul...
متن کاملBistability in the Electric Current through a Quantum-Dot Capacitively Coupled to a Charge-Qubit
We investigate the electronic transport through a single-level quantum-dot which is capacitively coupled to a charge-qubit. By employing the method of nonequilibrium Green's functions, we calculate the electric current through quantum dot at finite bias voltages. The Green's functions and self-energies of the system are calculated perturbatively and self-consistently to the second order of inte...
متن کاملMaximally entangling tripartite protocols for Josephson phase qubits
Superconducting circuits with Josephson junctions have attracted considerable attention as promising candidates for scalable solid-state quantum computing architectures. The story began in the early 1980’s, when Tony Leggett made a remarkable prediction that under certain experimental conditions the macroscopic variables describing such circuits could exhibit a characteristically quantum behavi...
