论文摘要
CNOT栅极是一个两倍的门，对于通用量子计算至关重要。在基于Majorana的Qubits中实施它的公认方法依赖于（联合）Majorana Parities的后续测量。我们提出了一种替代方案，该方案通过少数系统参数的自动控制操作受保护的CNOT门，而无需进行任何测量。我们展示了Majoranas之间的成对耦合的绝热调整如何牢固地导致两个量子位的完整纠缠，而对于参数的控制中的微小变化不敏感。
The CNOT gate is a two-qubit gate which is essential for universal quantum computation. A well-established approach to implement it within Majorana-based qubits relies on subsequent measurement of (joint) Majorana parities. We propose an alternative scheme which operates a protected CNOT gate via the holonomic control of a handful of system parameters, without requiring any measurement. We show how the adiabatic tuning of pair-wise couplings between Majoranas can robustly lead to the full entanglement of two qubits, insensitive with respect to small variations in the control of the parameters.
