A thought experiment called Schrödinger's cat illustrates the measurement problem. A mechanism is arranged to kill a cat if a quantum event, such as the decay of a radioactive atom, occurs.

May 22, 2023 · At the heart of this bizarreness is what’s called the measurement problem. Standard quantum mechanics accounts for what happens when you measure a quantum system: essentially, …

The lack of a precise principle to decide which evolution will arise has created a constellation of puzzles known at the "measurement problem." The best known example is "Schroedinger's cat," a thought …

Feb 26, 2025 · Yet, amid the cacophony of competing interpretations, the problem today is not as impenetrable as it once seemed. This paper reviews the current status of the Measurement Problem, …

Mar 23, 2025 · Despite significant progress in understanding quantum phenomena, the measurement problem remains one of the most profound questions in physics and philosophy, inviting further …

Jun 13, 2025 · Measurements play a specific role in quantum mechanics; only measurements allow us to catch a glimpse of the eluding physical reality. However, there is something deeply unsatisfactory …

Assuming that the existence of two ill-defined categories of fundamental physical laws is rejected, there remains the problem of accounting for the absence of superposition states in measurements of …

What is the measurement problem? Quiz: what kind of quantum mechanic are you? “[The Copenhagen interpretation] has stood the test of time, and emerged unscathed from every experimental challenge.

May 29, 2023 · The measurement problem is a fundamental issue in quantum mechanics that arises from the apparent contradiction between the deterministic evolution of a quantum system’s …

However, in the last decades, the situation has profoundly changed and it is time to consider measurement a fundamental part of quantum mechanics, even, to a certain extent, an important …
