论文摘要
由于它们的强大相互作用，Rydberg原子可用于实现快速的两倍纠缠大门。我们提出了将通用的两数Quibit Rydberg-Blockade Gate的概括性概括到多Quit的Rydberg-Blockade门，该门均涉及许多控制量尺寸和许多目标量子。这是通过使用强大的微波场来打扮附近Rydberg状态来实现的，从而导致不对称的封锁，其中控制目标相互作用比控制键盘和目标目标触头相互作用要强得多。这些多价门的实现可以大大简化量子算法和状态准备。为了说明这一点，我们表明只能使用三个门，误差为7.8％。
Due to their strong and tunable interactions, Rydberg atoms can be used to realize fast two-qubit entangling gates. We propose a generalization of a generic two-qubit Rydberg-blockade gate to multi-qubit Rydberg-blockade gates which involve both many control qubits and many target qubits simultaneously. This is achieved by using strong microwave fields to dress nearby Rydberg states, leading to asymmetric blockade in which control-target interactions are much stronger than control-control and target-target interactions. The implementation of these multi-qubit gates can drastically simplify both quantum algorithms and state preparation. To illustrate this, we show that a 25-atom GHZ state can be created using only three gates with an error of 7.8%.
