论文摘要
无相互作用的测量和反事实计算的可能性是20年前大约在20年前指出的量子力学的引人注目的特征。我们通过简单的量子电路以实际的5 Q量，15克和20量IBM量子计算机实现此类现象。结果通常接近理论期望。对于较大的电路（有许多大门和更大的错误），我们实施了一个简单的缓解程序，可以显着改善性能。
The possibility of interaction-free measurements and counterfactual computations is a striking feature of quantum mechanics pointed out around 20 years ago. We implement such phenomena in actual 5-qubit, 15-qubit and 20-qubit IBM quantum computers by means of simple quantum circuits. The results are in general close to the theoretical expectations. For the larger circuits (with numerous gates and consequently larger errors) we implement a simple error mitigation procedure which improve appreciably the performance.
