Popper's experiment is an experiment proposed by the philosopher Karl Popper to put to the test different interpretations of quantum mechanics (QM). In fact, as early as 1934, Popper started criticising the increasingly more accepted Copenhagen interpretation, a popular subjectivist interpretation of quantum mechanics. Therefore, in his most famous book Logik der Forschung he proposed a first experiment alleged to empirically discriminate between the Copenhagen Interpretation and a realist interpretation, which he advocated. Einstein, however, wrote a letter to Popper about the experiment in which he raised some crucial objections and Popper himself declared that this first attempt was "a gross mistake for which I have been deeply sorry and ashamed of ever since".

| - تجربة بوبر هي التجربة التي اقترحها الفيلسوف كارل بوبر وذلك لاختبار مختلف تفسيرات ميكانيكا الكم (QM). في الواقع، وفي وقت مبكر من عام 1934، بدأ بوبر ينتقد تفسير كوبنهاغن الأكثر قبولا على نحو متزايد، وهو تفسير ذاتي موضوعي من تفسيرات ميكانيكا الكم. لذلك، في كتابه الأكثر شهرة Logik Der Forschung اقترح أول تجربة يُزعم أنها تُميز بشكل تجريبي بين تفسير كوبنهاجن وتفسير واقعي، وهو ما دعاه. ومع ذلك، كتب أينشتاين رسالة إلى بوبر عن التجربة التي أثار فيها بعض الاعتراضات الحاسمة وكان بوبر نفسه قد أعلن أن هذه المحاولة الأولى كانت «خطأً جسيماً كنت أشعر بالأسف الشديد والخجل منه منذ ذلك الحين».

- 波普尔实验是由哲学家卡尔·波普尔提出的实验。在1934年，波普尔对哥本哈根解释，一种流行的量子力学主观解释，产生了怀疑，并提出了一个实验来检验它。 波普尔的实验是对一种争议说法的具体化，类似于阿爾伯特·愛因斯坦、鮑里斯·波多爾斯基和納森·羅森提出的EPR佯謬思想实验。 (zh)

- A experiência de Popper é um experimento proposto pelo filósofo Karl Popper em 1934 para testar a interpretação de Copenhaga e mecânica quântica. O experimento de Popper é uma realização de um argumento semelhante em sentido ao experimento mental de Einstein, Podolsky e Rosen (o paradoxo EPR), apesar de não ser tão conhecido. Enquanto o argumento de Einstein no experimento EPR envolvia um experimento limitado ao mental, Popper propôs um experimento físico para testar tal ação à distância. O mesmo foi realizado em 1999 por Kim e Shih utilizando fonte de fótons SPDC e concluíram que, através de um entrelaçamento, pode-se obter com precisão a posição de um fóton e portanto, confirmar a interpretação de Copenhaga, a interpretação mais conhecida da mecânica quântica, apresentada por Niels Bohr.

Einstein, however, wrote a letter to Popper about the experiment in which he raised some crucial objections and Popper himself declared that this first attempt was "a gross mistake for which I have been deeply sorry and ashamed of ever since". Popper, however, came back to the foundations of quantum mechanics from 1948, when he developed his criticism of determinism in both quantum and classical physics.As a matter of fact, Popper greatly intensified his research activities on the foundations of quantum mechanics throughout the 1950s and 1960s developing his interpretation of quantum mechanics in terms of real existing probabilities (propensities), also thanks to the support of a number of distinguished physicists (such as David Bohm).

Antes dessa experiência, Sudbery apontou que o resultado desta poderia ser equacionado: Existem várias interpretações da mecânica quântica que não concordam umas com as outras. Apesar de suas diferenças, elas são experimentalmente quase indistinguíveis umas das outros. A interpretação de Copenhaga afirma que observações conduzem a um colapso da função de onda, assim sugerindo o resultado contra-intuitivo que dois sistemas separados, não interativos requerem ação à distância. Popper argumentou que tal não-localidade conflita com o senso comum, com o que também era conhecido ao tempo da astronomia e do "sucesso técnico da física." "Eles todos sugerem a realidade do tempo e a exclusão da ação à distância." (pt)
