Published in Physical Review Letters, the work involves teams at Stevens Institute, Colorado State University and NIST using trapped-ion clocks with aluminum or ytterbium ions.
Researchers say combining ultra-precise clocks with quantum-computing methods could detect whether a single clock can tick at multiple rates simultaneously and become entangled with its motion.
The proposal aims to unite relativity and quantum theory experimentally, with scientists saying existing squeezing techniques and improving ion-clock precision may soon make the effect measurable.
Could a single clock soon prove it is both younger and older, rewriting our fundamental understanding of time?
Will proving time is quantum finally unite relativity and quantum mechanics, solving physics' greatest mystery?
If time itself can exist in a superposition, what does this reveal about the nature of cause and effect?
Experimental Proposal to Demonstrate Quantum Superposition of Time Using Trapped Ion Optical Clocks
Overview
In April 2026, researchers led by Igor Pikovski published a groundbreaking study proposing an experiment to show that time can exist in a quantum superposition, flowing at different rates simultaneously within a single system. This idea builds on earlier theoretical work and combines principles from Einstein's relativity and quantum mechanics, particularly the concept of the quantum twin paradox. Decades of advances in laser cooling, ion trapping, and quantum control, along with recent improvements in state preparation, have made this experiment feasible. While the proposal has sparked excitement and skepticism, ongoing theoretical and experimental efforts aim to validate this revolutionary concept by 2029, potentially reshaping our understanding of time and physics.
