Physicists Realize Non-Causal Quantum Eraser Concept

riNews, Quantum Physics6 Comments

Whether a quantum object behaves like a wave or like a particle depends on the tool used to observe the system, and thus on the type of measurement performed. Now, a team of physicists at the University of Vienna, Austria, and the Austrian Academy of Sciences has taken this phenomenon to the extreme by performing measurements on two photons placed 144 km apart. … Read More

More Quantum Weirdness

riQuantum Physics1 Comment

Quantum physics is getting real — and getting really weird. If the strange properties of entanglement, teleportation and superposition can be harnessed, it could revolutionize computing, communication, banking and much, much more. That’s a big “if.” But several reports over the past few days suggest that folks are willing to spend millions of dollars to turn theory into reality: • Can … Read More

Quantum jumps are not objective events? Precisely.

riNews, Quantum Physics3 Comments

The famous physicist Niels Bohr first conceived of the notion of quantum jumps, or quantum leaps, in 1913. Bohr understood quantum jumps as objective events in which an atom emits or absorbs a photon, causing an electron to jump from one energy level – or quantum state – to another inside the atom. But a few decades later, when physicists … Read More

The Meaning of Complementarity

riQuantum Physics2 Comments

By Amit Goswami, Ph.D. Quantum physics is finally coming of age.  The film The Quantum Activist made famous the line “quantum physics is the physics of possibilities.”  And the idea that consciousness chooses actuality from these possibilities must be getting well known too since even the New York Times columnist David Brooks commented in a recent column that quantum physics has … Read More
