Target qubit decoupling in echo cross-resonance gates

Systems, computer-implemented methods, and/or computer program products are provided that may assist in target qubit decoupling in echo cross-resonance gates. In accordance with an embodiment, a computer-implemented method may include receiving, by a system operatively coupled to a processor, both cross-resonant pulses and decoupling pulses at a target qubit. The cross-resonant pulse propagates to the target qubit via the control qubit. The computer-implemented method may further include receiving, by the system, a state reversal pulse at the control qubit. The computer-implemented method may further include receiving, by the system, both a phase-inverted cross-resonant pulse and a phase-inverted decoupling pulse at the target qubit. The phase-inverted cross-resonant pulse propagates to the target qubit via the control qubit. 提供了可以协助在回波交叉谐振门中的目标量子比特去耦的系统、计算机实现的方法、和/或计算机程序产品。根据实施例，计算机实现的方法可以包括通过操作性地耦接到处理器的系统在目标量子比特处接收交叉谐振脉冲和去耦脉冲两者。交叉谐振脉冲经由控制量子比特传播到目标量子比特。计算机实现的方法可以进一步包括由该系统在控制量子比特处接收状态反转脉冲。计算机实现的方法可以进一步包括由该系统在
