The Quantum World Denies Objective Reality ⚡ экспресс
Instead of traditional Leggett–Garg tests with rigid constraints, the authors used the method of unlimited weak measurements: two identical weak detectors performed measurements with minimal disruption, and then specific outcomes were post-selected. On IBM and IonQ quantum computers, a violation of objective reality was recorded with a record significance of 10 sigma — well above the threshold for a scientific discovery. The result proves that particles do not have pre-existing values. Additionally, high fidelity of parametric two-qubit gates — key elements of a quantum computer — was confirmed.
Reality is like an undeveloped photograph: before measurement, it remains just a cloud of possibilities. Only when we 'develop' it through observation does the particle acquire definite properties. This view was confirmed by experiments on IBM and IonQ quantum computers using weak measurements—a delicate method akin to developing film in dim light so as not to overexpose the 'photograph' entirely. Back in the 1960s, John Bell proposed searching for hidden parameters, and later Yakir Aharonov developed the technique of weak measurements. Today, it allows peering into the quantum world with minimal disturbance: entropy barely increases, unlike with crude methods. This approach is reminiscent of spectroscopy—studying matter through light without direct contact. The result: confidence in the absence of hidden properties exceeded the usual threshold by 10 times. This is not just philosophy—such experiments help test the logic gates of quantum computers. And the most unexpected twist: weak measurements can capture the effects of ultra-rare events, like photographic film sensitive to single photons.
🎯 Weak measurements are so delicate that they can pick up an effect even if it occurs with a probability of one in a billion—like photographic film capturing single photons.
🎬 In 'The Matrix', reality was an illusion dependent on perception. Quantum experiments show that at the microlevel, the world is indeed 'undefined' until it is observed.
