利用 Coleman 瞬子技术与 Banks 和 Bender 方法的强大结合，在两个相同电容耦合相位量子位的系统中从亚稳态真空隧道穿出的零温度速率的指数因子以封闭形式计算为中间耦合特殊情况 C=C_J/2 的不对称参数的二阶。
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=C_J/2.
