Quantum scientists have shown it’s possible to generate Schrödinger cat states in warmer conditions, challenging the assumption that cold is essential for quantum effects. Credit: SciTechDaily.com *************************************************************************** Researchers have pulled off a quantum feat that defies traditional expectations—they’ve created Schrödinger cat states not from ultra-cold ground states, but from warm, thermally excited ones. Using a superconducting qubit setup, the team demonstrated that quantum superpositions can exist even at higher temperatures, overturning the long-held belief that heat destroys quantum effects. This breakthrough not only validates Schrödinger’s original “hot cat” concept but also paves the way for more practical and accessible quantum...

In a groundbreaking experiment, UNSW researchers successfully applied the Schrödinger’s cat concept using an antimony atom to enhance quantum computations. This method significantly improves the reliability of quantum data processing and error correction, potentially accelerating the advent of practical quantum computing.

Physicists have learned how they could breed Schrödinger cats in optics. Scientists tested a method that could potentially amplify superpositions of classical states of light beyond microscopic limits and help determine the boundaries between the quantum and classical worlds. ... Co-author and University of Calgary graduate student Anastasia Pushkina explains: "The idea of the experiment was proposed in 2003 by the group of Professor Timothy Ralph of the University of Queensland, Australia. In essence, we cause interference of two "cats" on a beam splitter. This leads to an entangled state in the two output channels of that beam splitter. In...

Dear Cecil: Cecil, you're my final hope Of finding out the true Straight Dope For I have been reading of Schroedinger's cat But none of my cats are at all like that. This unusual animal (so it is said) Is simultaneously live and dead! What I don't understand is just why he Can't be one or other, unquestionably. My future now hangs in between eigenstates. In one I'm enlightened, the other I ain't. If you understand, Cecil, then show me the way And rescue my psyche from quantum decay. But if this queer thing has perplexed even you, Then I...
