Sapphire crystal resonator used to explore the limits of quantum mechanics
Matteo Fadel/ETH Zurich
Quantum effects have been demonstrated on one of the largest scales ever, pushing the boundaries of the quantum world. A crystal of 10^16 atoms he placed in a superposition of two quantum states, breaking the previous record of only 2000 atoms.
When a particle is in a quantum superposition of two states, it occupies both different states simultaneously. The most famous example is Schrödinger’s cat, a theoretical cat …
