QUANTUM SIMULATIONS ARE STARTING TO LOOK A LOT LIKE OUR UNIVERSE
Physicists just used IBM’s quantum computers to simulate matter under extreme conditions - like the Big Bang or inside neutron stars.
They built scalable quantum circuits to recreate particle collisions and vacuum states, modeling the strong force that holds atoms together.
Over 100 qubits deep, these simulations go where classical supercomputers flat-out fail.
They're not saying we live in a simulation… but we’re definitely getting closer to building one.

THE HIDDEN COST OF KNOWING TIME IN THE QUANTUM WORLD
Quantum clocks were supposed to be ultra-efficient. But researchers just found out the real energy hog isn’t the clock - it’s you trying to read it.
In a new study, scientists built a quantum clock powered by single electrons hopping between two nano-sized zones. Each hop = one tick. Simple, right? But when they measured those hops using high-tech sensors, they burned up to a billion times more energy than the clock used to tick.
Let that sink in: observing time at the quantum level costs way more energy than keeping time. The moment you try to turn those quantum ticks into classical data? Boom - entropy skyrockets.
This shatters the old belief that measurement is cheap in quantum physics. Turns out, just watching the clock is what makes time irreversible - giving it a forward direction.
So if you’re dreaming of ultra-efficient quantum tech, don’t just build better clocks. Fix how we look at them.
