Breakthrough technology uses multiplexing entanglement to make an ultra-secure quantum internet.
- Scientists devise the largest-ever quantum communications network.
- The technology is much cheaper than previous attempts and promises to be hacker-proof.
- The 'multiplexing' system devised by the researchers splits light particles that carry information.

A physics paper proposes neither you nor the world around you are real.
- A new hypothesis says the universe self-simulates itself in a "strange loop".
- A paper from the Quantum Gravity Research institute proposes there is an underlying panconsciousness.
- The work looks to unify insight from quantum mechanics with a non-materialistic perspective.
