The double-slit experiment,

which slit the particle passes through,

the interference pattern disappears,

indicating particle-like behavior.

about the probabilistic interpretation

of quantum mechanics,

advocating for

a more deterministic explanation.

This led to

the famous Einstein-Bohr debates,

where Niels Bohr argued

that any measurement

to determine the particle's path

would introduce uncertainty,

thus eliminating the interference pattern,

based on the uncertainty

and complementarity principles.

Modern understanding recognizes

the double-slit experiment

as a key example

アルバート・アインシュタインは相対性理論で有名ですが、量子力学の解釈、特に二重スリット実験においても重要な役割を果たしました。アインシュタインは相対性理論で広く知られていますが、1921年のノーベル物理学賞は光電効果に関する仮説に対して授与されました。この仮説は、光が粒子的性質を持つことを示唆し、量子力学の発展に大きく貢献しました。二重スリット実験は量子力学の基本的な実験であり、電子や光子が二つのスリットを通過する際に干渉パターンを形成し、波のように振る舞うことを示します。しかし、どちらのスリットを通過したかを観測しようとすると、干渉パターンが消失し、粒子的な振る舞いを示します。アインシュタインは量子力学の確率論的解釈に疑問を呈し、より決定論的な説明を求めました。これにより、ニールス・ボーアとの有名な論争が生まれました。ボーアは、粒子の経路を特定するための測定が不確定性を導入し、干渉パターンを消失させると主張しました。現代の理解では、二重スリット実験は波と粒子の二重性を示す重要な例とされ、観測されるまでは波のように振る舞い、観測されると粒子的に振る舞うことが認識されています。この実験は、観測による波束の収縮という概念を示し、量子コンピュータの動作原理にも関連しています。アインシュタインの批判は量子力学の解釈に関する議論を深め、量子力学の基礎に関する研究を長年にわたって指針としてきました。
