Quantum Today: Quantum Energy Teleportation – Activating Ground State Energy

Thursday, April 27, 2023 12:00 pm - 1:00 pm EDT

Join us for Quantum Today, where we sit down with researchers from the University of Waterloo’s Institute for Quantum Computing (IQC) to talk about their work, its impact and where their research may lead.

In quantum mechanics, “nothing” is hard to come by. Even the vacuum state has spontaneous energy fluctuations, although extracting useful work from them is notoriously difficult. By taking advantage of entanglement in the lowest-energy state of a system, it is possible to spend energy in one region to gain information that allows energy extraction somewhere else. This protocol, called quantum energy teleportation, was a purely theoretical notion until a recent result by IQC and University of Waterloo researchers, where they demonstrated the protocol using nuclear magnetic resonance. In this instalment of Quantum Today, University of Waterloo professor Eduardo Martín-Martínez and IQC alumnus Hemant Katiyar discuss taking ideas from quantum thermodynamics and designing an experiment to test the foundations of quantum mechanics.

Find their publication, titled “Experimental activation of strong local passive states with quantum information”, in Physical Review Letters and on the arXiv, and read more on IQC news: “IQC researchers bring theory to reality with a new experiment.”
