Quantum-Like Behavior Unveiled in Bouncing Droplets: A Surprising Discovery

Physicists at MIT have discovered that tiny droplets of oil bouncing down channels in a vibrating fluid exhibit behavior similar to a famous quantum thought experiment known as the Elitzur-Vaidman bomb tester. The droplets, acting as quantum particles, displayed interference patterns when merging with each other, similar to the probabilities created by superposition in quantum systems. This surprising result suggests a connection between classical and quantum physics, shedding light on the collapse of quantum wave functions. The findings challenge the notion that such behavior can only be understood from a quantum perspective and provide insights into the bridge between classical and quantum realms.

Challenging the Quantization of Gravity: A Physicist's Bet

Physicist Jonathan Oppenheim from University College London is challenging the prevailing belief that gravity must be quantized. Oppenheim argues that gravity, unlike other forces, describes the geometry and curvature of space-time itself, making it fundamentally classical. He is developing hybrid quantum-classical theories that aim to unify classical gravity and quantum mechanics. Oppenheim's research explores the interrelation between the classical and quantum worlds, seeking a deeper theory that is neither purely quantum nor classical. He has made a bet with colleagues in string theory and loop quantum gravity, wagering that space-time is not quantized. Oppenheim believes that the next theory of gravity will be something entirely different from classical or quantum, and experiments are being conducted to test the nature of gravity on the smallest scales.

Physicists Achieve Quantum Superposition with Largest Object Yet

Physicists have created a Schrödinger's cat that weighs 16 micrograms, making it the fattest quantum cat to date. The cat was created by putting a small crystal in a superposition of two oscillation states, equivalent to alive or dead in Schrödinger's thought experiment, and coupling it with a superconducting circuit. The team's research, published in the journal Science, tests the muddy waters where the world of quantum mechanics gives way to the classical physics of the familiar macroscopic world. The research takes Schrödinger’s famous thought experiment and gives it some practical applications, such as helping reduce noise in the interferometers that measure gravitational waves.
