How Space and Time Could Be a Quantum Error-Correcting Code
The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness.
Real-Life Schrödinger’s Cats Probe the Boundary of the Quantum World
Recent experiments have put relatively large objects into quantum states, illuminating the processes by which the ordinary world emerges out of the quantum one.
Solution: ‘Taming Quantum Weirdness’
A simple analogue could offer insights into one of the most astonishing results of quantum mechanics.
Entanglement Made Simple
How quantum entanglement connects with the “many worlds” of quantum theory.
Quantum Weirdness Now a Matter of Time
Bizarre quantum bonds connect distinct moments in time, suggesting that quantum links — not space-time — constitute the fundamental structure of the universe.
How Quantum Pairs Stitch Space-Time
New tools may reveal how quantum information builds the structure of space.
Wormholes Untangle a Black Hole Paradox
A bold new idea aims to link two famously discordant descriptions of nature. In doing so, it may also reveal how space-time owes its existence to the spooky connections of quantum information.
Time’s Arrow Traced to Quantum Source
A new theory explains the seemingly irreversible arrow of time while yielding insights into entropy, quantum computers, black holes, and the past-future divide.
