In honor of the centennial celebrations, and under the auspices of the Quantum Center of Tel Aviv University, I am organizing, together with cellist Dr. Shulamit Sarid, a unique concert that will tell the story of quantum mechanics, from the creation of the universe to the present.

The measurement problem

Does the wave function describe reality or only our knowledge of it? Three fundamental problems—the result, the statistics, and the effect—reveal that the issue of measurement is not just a philosophical question.

Bell's Inequality – Not What You Thought

  • One response
Dr. Noam Hai debunks the myths surrounding Bell's inequality and clarifies what it really says – and what it doesn't. Does quantum mechanics put an end to determinism, or are we perhaps giving up too quickly?

The Code of the Universe – Does Nature Always Choose the Shortest Path? Article and Invitation to a Lecture

  • 3 תגובות
Does nature always choose the shortest path? From the philosophy of Aristotle, through the discoveries of Heron, Fermat, and Newton, to Richard Feynman's revolutionary interpretation of quantum mechanics, it turns out that nature operates according to a simple principle.

Scientists have developed a new method of controlling quantum states using magnetic qubits

  • One response
Spin-polarized currents can also be used to control the quantum states of individual electronic spins. The results of the research, published in the scientific journal Science, may be used in various technologies in the future, for example in the control of my condition
