For the first time, energy has been quantumly transmitted to multiple recipients simultaneously.
Abstract

For the first time, scientists have moved energy between three, four, and five quantum particles — not just two. It’s like splitting your energy among friends through an invisible bond called quantum entanglement. The feat brings us closer to quantum networks that handle their own power. Might we one day beam energy across long distances without wires?

The energy between particles is distributed like money in a joint account. One person makes a deposit by performing a measurement on their particle, instantly adding energy to the shared pot. But the others can only withdraw their share after a classical signal, which obeys the speed of light.

The trick is that the particles are first placed in a superposition — a state where each exists in multiple versions at once. A measurement triggers a collapse — picking just one option — and the energy kind of 'pours' into the network. Previously, this was only possible with two particles. Now, using an IBM quantum processor, physicists have done the experiment with three, four, and five particles. They used a special type of connection that doesn't break if one particle drops out. Due to imperfect equipment, decoherence occurred — a loss of quantum properties — but the result was still noticeable.

The most surprising part: the particle being measured remains untouched, while the energy comes from the web of quantum entanglement — that strange connection Erwin Schrödinger called the mystery of the micro-world. John Stewart Bell later proved that such correlations are stronger than any classical explanation. The energy was always 'spread' across all participants; the measurement only redistributes it. So the total balance adds up, and quantum information — knowledge about the system — turns into real work.

🎯 Energy isn't teleported in the literal sense — it's initially distributed among the entangled particles, like shared savings, and only becomes available in a usable form.
